How to source continuous pulses without any measurement
This material shows how to setup the instrument to source continuous pulses without any measurement using the
B2901/02/11/12A, through example to source 2 V continuous pulses with the timing parameters such as 300 us pulse
delay, 200 us pulse width and 500 us source trigger period.
Figure 1 shows the timing chart for the continuous pulse source.

It is required to abort the instrument when you’d like to stop sourcing continuous pulses.
This material also shows how to abort the instrument to stop continuous pulses.
Setting up the pulse condition
Step 1. Press to edit the source function, and then select to set the source function to the voltage
