To adjust the grid intensity

To adjust the display grid (graticule) intensity:

1 Press the [Display] key.

2 Press the Graticule softkey; then, turn the V0 knob to change the intensity of the displayed grid.

The intensity level is shown in the Graticule softkey and is adjustable from 0 to 100%.

To adjust the display brightness

To adjust the display intensity:

1 Press the [Display] key.

2 Press the Brightness softkey; then, turn the V0 knob to change the intensity of the displayed grid.

The intensity level is shown in the Brightness softkey and is adjustable from 0 to 100%.

To select the grid type

Press the Grid softkey; then, turn the V0 knob to select the grid type. You can also press Grid softkey continuously

to select “Full”, “Half” or “None”.

? Full — the normal oscilloscope grid. Turn on the background solid grid.

? Half — Turn on the background dotted grid.

? None— Turn off the background grid.

To adjust waveform intensity

You can adjust the intensity of displayed waveforms to account for various signal characteristics, such as fast time/div

settings and low trigger rates.

Increasing the intensity lets you see the maximum amount of noise and infrequently occurring events. Reducing the

intensity can expose more detail in complex signals as shown in the following figures.

1 Press the [Display] key -> Intensity softkey to illuminate it.

2 Turn the V0 knob to adjust the waveform intensity.

Waveform intensity adjustment affects analog channel waveforms only (not math waveforms, reference waveforms,

digital waveforms, etc.).

To disable or re-enable vectors

1 Press [Display] key on the front panel.

2 Press Type softkey to toggle between Vectors and Dots.

When Vectors are enabled, Vectors draw a line between consecutive waveform data points.

? Vectors give an analog look to a digitized waveform. Complex analog signals like video and modulated signals show

analog-like intensity information with vectors.

? Vectors allow you to see steep edges on waveforms, such as square waves.

? Vectors allow subtle detail of complex waveforms to be viewed, much like an analog oscilloscope trace, even when

the detail is just a small number of pixels.

You may want to turn vectors off when highly complex or multivalued waveforms are displayed. Turning vectors off

may aid the display of multivalued waveforms such as eye diagrams.

Having vectors on does not slow down the display rate.

Digital channels on a mixed-signal oscilloscope are not affected by the Vectors setting. They are always displayed

with vectors on. They also only contain one acquisition worth of information.

To display waveforms as vectors or dots

This series of oscilloscopes are designed to operate optimally with vectors (connect the dots). This mode produces

the most insightful waveforms for most situations.

You can disable vectors to view just waveform data points.

Event Table

Event table is a powerful tool for investigating protocol failures. You can use event table to view large amounts of

packet level serial data in a tabular format.

To use the Event Table:

1 Press the [Trig Menu] key.

2 Select UART, LIN, CAN, SPI or IIC by pressing Type softkey.

3 Set up trigger and decode on the serial data signals to be analyzed.

3 press the Event Table softkey to open Event Table Menu and display event table window on the screen.

4 Press Status softkey to run an event.

Triggering on Serial Data

In some cases, such as when triggering on a slow serial signal (for example, I2C, SPI, CAN, LIN, etc.) it may be necessary

to switch from the Auto trigger mode to the Normal trigger mode to prevent the oscilloscope from Auto-triggering and

stabilize the display. You can select the trigger mode by pressing the [Trig Menu] key, then the Mode softkey.

Also, the threshold voltage level must be set appropriately for each source channel. The threshold level for each serial

signal can be set in the Trigger Menu. Press the [Trig Menu] key, then the Idle Level softkey.

Available serial decodes are: UART (Universal Asynchronous Receiver/Transmitter) protocols, LIN (Local Interconnect

Network) serial buses, CAN (Controller Area Network) serial buses, SPI (Serial Peripheral Interface) serial buses, and IIC

(Inter-IC) serial buses.

To change the logic threshold for digital channels

1 Connect the logic probes to the Type C connectors on the device so that the LA Menu is displayed.

2 Press the Type softkey, then select a logic family preset or select User to define your own threshold.

The threshold you set applies to all channels within the selected D1, D2, D3, or D4 group. Each channel group

can be set to a different threshold if desired.

Values greater than the set threshold are high (1) and values less than the set threshold are low (0).

If the Type softkey is set to User, press the Thresholds softkey, then turn the V0 knob to set the logic threshold.

There is one User softkey for each group of channels.
