03 | Keysight | Using an External Trigger to Generate Pulses with the B2960A – Demo Guide
Concept
Figure 1 illustrates the connection diagram and basic setup conditions used in the demo
to make the B2960A series generate pulses whenever it receives an external trigger sig-
nal. Use the settings shown below to program the B2960A source. Connect an oscillo-
scope to the test setup to monitor the results.

Figure 2 shows the parameters used to define the timing parameters of the pulses from
the instrument's front panel. Once these parameters have been specified, the source
value is output immediately after pressing
trigger condition and initiating the channel, the instrument will be ready to receive an
external trigger signal and generate pulsed output.
