RE: How to Use the Burst Function of HDG6000B?

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.

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.

? 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.

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.

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.

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.

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.
