Analog triggering example with digitize function
This example shows how to set up analog trigger for a digitize function. The trigger is used to pulse
the external out.
When the script runs, it opens the Graph tab on the front panel. To view the data, open the Scale tab
and set X-Axis Method to Track Group.
Analog trigger example — SCPI
This code resets the instrument, and sets it to measure digitize volts on the 10 V range. Sample rate
is set to 100,000 samples per second on the fastest aperture. DC coupling and input impedance are
selected. The digitize count is set to make 1000 readings for each trigger condition.
The buffer size is set to 100,000 readings.
The analog trigger is set to edge with a rising slope and level of 0.5 V. High frequency rejection is
disabled to allow triggering on a fast edge.
Configures the instrument to run the digitizer every time the analog trigger conditions are met and
push external trigger pulses out that are synchronized with the analog trigger.
Opens the graph screen.
