To Output a Burst
You can output the burst at a rate determined by the internal rate generator or the signal level on the
front-panel Sync/Mod/Trig connector. For this example, you will output a three-cycle sine wave with
a 10 ms burst period. You will not change the other parameters from their default settings: internal
burst source and 0 degree starting phase.

1 Select the function and amplitude of the burst.
For burst waveforms, you can select sine, square, ramp, pulse, or arbitrary waveforms (noise is allowed
only in the “gated” burst mode and dc is not allowed). For this example, select a sine wave with an
amplitude of 200mV.
2 Select the burst mode.
Press [attach]3002[/attach] and then verify that the “N Cycle” (internally-triggered) mode is currently selected.file:///C:\Users\ADMINI~1\AppData\Local\Temp\ksohtml5012\wps1.jpg

To Trigger a Burst
You can issue triggers from the front panel for bursts using a manual trigger or an internal trigger.
? Internal triggering is enabled with the default settings of the function generator. In this mode, the
function generator outputs continuously when the burst mode is selected.
? Manual triggering initiates one burst each time you press theTrigger key from the front-panel.
Continue pressing this key to re-trigger the function generator.

To Select Burst
Press Burst key to output a burst using the present settings for frequency, output amplitude, and offset voltage. (the backlight of the key goes on)
[attach]3077[/attach]
Note:
A. The function generator will not allow burst to be enabled at the same time that sweep or any modulation mode is enabled. When you enable burst, the sweep or modulation mode is turned off.
B. You must enable burst before setting up any of the other burst parameters.
Author: WisdomAugust Time: 2019-8-12 07:58
Burst Type
You can use burst in one of three modes as described below. The function generator enables one burst
mode at a time based on the trigger source and burst source that you select (see the table below).
[attach]3078[/attach]
Author: WisdomAugust Time: 2019-8-13 13:25
N Cycle Burst (Triggered Burst Mode)
In this mode (default), the function generator outputs a waveform with a specified number of cycles
(burst count) each time a trigger is received. After the specified number of cycles have been output,
the function generator stops and waits for the next trigger. You can configure the function generator
to use an internal trigger to initiate the burst or you can provide an external trigger by applying a trigger
signal to the front-panel Sync/Mod/Trig connector, or sending an internal trigger command manually
by pressing the front-panel Trigger key.

Infinite Cycle Burst (Triggered Burst Mode)
In this mode , the function generator outputs continuous waveforms with a infinite number of cycles
after receiving trigger signal. You can configure the function generator to use an external trigger by
applying a trigger signal to the front-panel Sync/Mod/Trig connector, or sending an trigger command
manually by pressing the front-panel Trigger key.

Gated Burst ( External Gated Burst Mode)
In this mode, the output waveform is either “on” or “off ” based on the level of the external signal applied
to the front-panel Sync/Mod/Trig connector. When the gate signal is true, the function generator outputs
a continuous waveform. When the gate signal goes false, the current waveform cycle is completed and
then the function generator stops while remaining at the voltage level corresponding to the starting burst
phase of the selected waveform. For a noise waveform, the output stops immediately when the gate signal
goes false.

Gated Burst
Author: WisdomAugust Time: 2019-8-16 11:08
Gated Burst
When the gated mode is selected, the burst count, burst period, and trigger source are ignored (these
parameters are used for the triggered burst mode only). If a manual trigger is received, it is ignored and
no error will be generated.
When the gated mode is selected, you can also select the polarity of the signal on the front-panel
Sync/Mod/Trig connector.
Front-Panel Operation: After enabling bursts, press the N Cycle (triggered), Inf Cycle or Gate softkey.
To select the polarity of the external gate signal on the Sync/Mod/Trig connector, press the Polarity
softkey. The default polarity is Positive.
[attach]3085[/attach]
Author: WisdomAugust Time: 2019-8-17 08:06
Waveform Frequency
The waveform frequency defines the repetition rate of the burst waveform in the triggered and external
gated modes. In the triggered mode, the number of cycles specified by the burst count is output at the
waveform frequency. In the external gated mode, the waveform frequency is output when the external
gate signal is true.
Keep in mind that the waveform frequency is different than the “burst period” which specifies the interval
between bursts (triggered mode only).
– Waveform frequency: 1 mHz to 200 MHz (HDG6202B) (limited to 200 kHz for ramp waveforms). The
default waveform frequency is 1kHz. (For an internally triggered burst waveform, the minimum frequency
is 2.001 mHz.) You can select a sine, square, or ramp waveform (pulse, noise, dc, and arbitrary waveforms
are not allowed).
– For sine and square waveforms, frequencies above 3 MHz are allowed only with an “infinite” burst count.
– Front-Panel Operation: To set the waveform frequency, press the Freq softkey for the selected function.
Then use the knob or numeric keypad to enter the desired frequency.

Burst Count
The burst count defines the number of cycles to be output per burst. Used in the triggered burst mode
only (internal or external source).
? Burst count: 1 to 2, 000, 000, 000 cycles, in 1 cycle increments. You can also select an infinite burst
count. The default is 1 cycle.
[attach]3134[/attach]
Author: WisdomAugust Time: 2019-9-3 08:34
? When the Internal trigger source is selected, the specified number of cycles is output continuously at
a rate determined by the burst period setting. The burst period defines the interval between bursts.
? When the Internal trigger source is selected, the burst count must be less than the product of the burst
period and the waveform frequency as shown below.
Burst Count < Burst Period X Waveform Frequency
? The function generator will automatically increase the burst period up to its maximum value to
accommodate the specified burst count (but the waveform frequency will not be changed).
? When the gated burst mode is selected, the burst count is ignored.
? Front-Panel Operation: To set the burst count, press the N Cycles softkey and then use the
knob or numeric keypad to enter the count.
To select an infinite count burst instead, press the Inf Cycles softkey.
Author: WisdomAugust Time: 2019-9-4 09:20
Burst Period
The burst period defines time from the start of one burst to the start of the next burst. Used in the internal
triggered burst mode only.
Keep in mind that burst period is different than the “waveform frequency” which specifies the frequency of
the bursted signal.
? Burst period: 2 ?s to 500 seconds. The default is 10 ms.
? The burst period setting is used only when Internal triggering is enabled. The burst period is ignored when
manual or external triggering is enabled (or when the gated burst mode is selected).
? It is not possible to specify a burst period which is too short for the function generator to output with the
specified burst count and frequency (see below). If the burst period is too short, the function generator
will automatically adjust it as needed to continuously
re-trigger the burst.
Burst Period > Burst Count ÷ Waveform Frequency + 200 ns
? Front-Panel Operation: To set the burst period, press the Period softkey and then use the knob or numeric
keypad to enter the period.
Author: WisdomAugust Time: 2019-9-5 09:05
Burst Phase
The burst phase defines the starting phase of the burst.
? Burst phase: 0 degrees to 360 degrees. The default is 0 degrees.

Author: WisdomAugust Time: 2019-9-11 08:13
? From the front panel, the starting phase is always displayed in degrees (radians are not available).
? For sine, square, and ramp waveforms, 0 degrees is the point at which the waveform crosses zero
volts (or the dc offset value) in a positive - going direction. For arbitrary waveforms, 0 degrees is the
first waveform point downloaded to memory. The burst phase has no effect on pulse or noise waveforms.
? The burst phase is also used in the gated burst mode. When the gate signal goes false, the current
waveform cycle is completed and then the function generator stops. The output will remain at the
voltage level corresponding to the starting burst phase.
? Front-Panel Operation: To set the burst phase, press the Phase softkey and then use the knob or
numeric keypad to enter the desired phase in degrees.

Burst Trigger Source
In the triggered burst mode, the function generator outputs a burst with the specified number of cycles
(burst count) each time a trigger is received. After the specified number of cycles have been output,
the function generator stops and waits for the next trigger. At power-on, the internally-triggered burst
mode is enabled.
? Burst trigger source: Internal, External, or Manual. The default is Internal.
? When the Internal (immediate) source is selected, the frequency at which the burst is generated is
determined by the burst period.
? When the External source is selected, the function generator will accept a hardware trigger applied to
the front-panel Sync/Mod/Trig connector. The function generator outputs the specified number of cycles
each time Sync/Mod/Trig receives a TTL pulse with the specified polarity. External trigger signals that
occur during a burst are ignored.
? When the Manual source is selected, the function generator outputs one burst each time the front-panel
Trigger key is pressed.
? When the External or Manual trigger source is selected, the burst count and burst phase remain in effect
but the burst period is ignored.
? Front-Panel Operation: Press the Source softkey to select the desired source . To specify whether the
function generator triggers on the rising or falling edge of the signal on the Sync/Mod/Trig connector,
select the desired edge by pressing the Slope softkey.

Author: WisdomAugust Time: 2019-9-17 08:05
Trigger Out Signal
A “trigger out” signal is provided on the frount-panel Sync/Mod/Trig connector (used with burst and
sweep only). When enabled, a TTL-compatible pulse waveform with either a rising edge (default) or
falling edge is output from the Sync/Mod/Trig connector at the beginning of the burst.
[attach]3155[/attach]
Author: WisdomAugust Time: 2019-9-18 08:48
? When the Internal (immediate) trigger source is selected the function generator outputs a square waveform
with a 50% duty cycle from the Sync/Mod/Trig connector at the beginning of the burst. The frequency of the
waveform is equal to the specified burst period.
? When the External trigger source is selected, the function generator automatically disables the “trigger out”
signal. The Sync/Mod/Trig connector cannot be used for both operations at the same time (an externally-
triggered waveform uses the same connector to trigger the burst).
? When the Manual trigger source is selected, the function generator outputs a pulse (>1 ?s pulse width) from
the Sync/Mod/Trig connector at the beginning of each burst.
Author: WisdomAugust Time: 2019-9-19 08:46
Triggering
Applies to sweep and burst only. You can issue triggers for sweeps or bursts using internal triggering,
external triggering, or manual triggering.
? Internal or “automatic” triggering is enabled when you turn on the function generator. In this mode,
the function generator outputs continuously when the sweep or burst mode is selected.
? External triggering uses the front-panel Sync/Mod/Trig connector to control the sweep or burst. The
function generator initiates one sweep or outputs one burst each time Sync/Mod/Trig receives a TTL
pulse. You can select whether the function generator triggers on the rising or falling edge of the external
trigger signal.
? Manual triggering initiates one sweep or outputs one burst each time you press Trigger key from the
front-panel. Continue pressing this key to re-trigger the function generator.
Author: WisdomAugust Time: 2019-9-20 08:46
Trigger Source Choices
Applies to sweep and burst only. You must specify the source from which the function generator will
accept a trigger.
? Sweep trigger source: Internal, External, or Manual. The default is Internal.
? The function generator will accept a manual trigger, a hardware trigger from the front-panel
Sync/Mod/Trig connector, or continuously output sweeps or bursts using an internal trigger.
At power-on, internal trigger is selected.
? Front-Panel Operation: After enabling sweeps or bursts, press the Source softkey to select
the desired source.
Author: WisdomAugust Time: 2019-10-8 08:28
Internal Triggering
In the internal trigger mode, the function generator continuously outputs the sweep or burst (as specified
by the sweep time or burst period). This is the default trigger source for front-panel use.
Manual Triggering
In the manual trigger mode (front panel only), you can manually trigger the function generator by pressing
the front - panel Trigger key. The function generator initiates one sweep or outputs one burst for each time
you press the key.
External Triggering
In the external trigger mode, the function generator will accept a hardware trigger applied to the front-panel
Sync/Mod/Trig connector. The function generator initiates one sweep or outputs one burst each time
Sync/Mod/Trig receives a TTL pulse with the specified edge.
? Front-Panel Operation: The external trigger mode is like the manual trigger mode except that you apply
the trigger to the Sync/Mod/Trig connector. To select the external source, press the Source softkey.
To specify whether the function generator triggers on the rising or falling edge, press the Slope softkey.

Author: WisdomAugust Time: 2019-10-10 08:04
This front-panel connector is used in the following modes:
? Triggered Sweep Mode: To select the external source, press the Source Ext softkey When the rising
or falling edge (you specify which edge) of a TTL pulse is received on the Sync/Mod/Trig connector, the
function generator outputs a single sweep.
? Externally-Modulated FSK Mode: To enable the externally-modulated mode, press the Source softkey
from the front-panel (FSK must be enabled). When a logic low level is present, the carrier frequency is
output. When a logic high level is present, the hop frequency is output. The maximum external FSK rate
is 100 kHz.
? Triggered Burst Mode: To select the external source, press the Source Ext softkey
(burst must be enabled). The function generator outputs a waveform with a specified number of cycles
(burst count) each time a trigger is received from the specified trigger source.
? External Gated Burst Mode: To enable the gated mode, press the Gated softkey (burst must be
enabled). When the external gate signal is true, the function generator outputs a continuous waveform.
When the external gate signal goes false, the current waveform cycle is completed and then the function
generator stops while remaining at the voltage level corresponding to the starting burst phase. For noise,
the output stops immediately when the gate signal goes false.

Dear Sirs, We would ask you kindly if the external trigger input can be different from ttl, example a spike. Thanks
Author: WisdomAugust Time: 2019-12-10 08:15
Sorry, HDG6000 can't support external trigger signal.
It only can support external clock source by 10MHz/5Vpp signal.
