Set up remote communications
You can run this application from the front panel or any of the supported communication interfaces for
the instrument (GPIB, USB, or ethernet).
The following figure shows the rear-panel connection locations for the remote communication
interfaces. For additional information about setting up remote communications, see
(on page 2-68).

Device connections
Use a Tektronix two-channel AFG (for example, AFG3102C or equivalent) to generate two
synchronous pulse signals. One signal is used to control the on and off state of nMOSFET. The other
is used as the external triggering signal for 2281S. For details, refer to the following table.
