To switch groups of channels on or off

1 Connect the logic probes to the Type C connectors on the device if the LA Menu is not already displayed.

2 Press the On (or Off) softkey for the D1 group, D2 group, D3 group, or the D4 group. Each time you press

the softkey, the softkey's mode toggles between Turn on and Turn off if its digital channels group source

connected to the logic probe.

Interpreting the digital waveform display

The following figure shows a typical display with digital channels.

Activity indicator When any digital channels are turned on, an activity indicator is displayed in the status line at

the bottom of the display.

Acquiring waveforms using the digital channels

When you press [Run/Stop] or [Single] to run the oscilloscope, the oscilloscope examines the input voltage at

each input probe. When the trigger conditions are met the oscilloscope triggers and displays the acquisition.

For digital channels, each time the oscilloscope takes a sample it compares the input voltage to the logic threshold.

If the voltage is above the threshold, the oscilloscope stores a 1 in sample memory; otherwise, it stores a 0.

7 Repeat these steps until you have connected all points of interest.

6 If you are working with tiny SMD parts with no exposed leads, you can solder a thin wire to

an exposed printed circuit board (PCB) trace gives you access to the signal.

5 Connect the grabber to a node in the circuit you want to test.

4 Connect a grabber to one of the probe leads. (Other probe leads are omitted from the figure for clarity.)

3 Connect the ground lead on each set of channels (each pod), using a probe grabber. The ground lead improves

signal fidelity to the oscilloscope, ensuring accurate measurements.

Digital Channels

To connect the digital probes to the device under test

1 If necessary, turn off the power supply to the device under test.

Turning off the power to the device under test would only prevent damage that might occur if you accidentally

short two lines together while connecting probes. You can leave the oscilloscope powered on because no

voltage appears at the probes.

2 Connect the digital probe to the DIGITAL connectors on the mixed-signal oscilloscope by the Type C cable.

The digital probe is keyed so you can connect it only one way. You do not need to power-off the oscilloscope.

CAUTION Probe cable for digital channels Use only the Hantek logic probe and accessory kit supplied with the

mixed-signal oscilloscope.

Absolute Value

The absolute value function changes negative values in the input to positive values

and displays the resulting waveform.
