SPGU Module
PG Operation Mode
In the PG mode (pulse generator operation mode), the SPGU outputs 2-level or
3-level pulse voltage as shown in Figure 7-16.
The SPGU channels simultaneously start the pulse output and repeat the output
every pulse period
. The channels continue the pulse output until the specified time
elapses or the repeat count reaches the specified number of pulses.
For the SPGU pulse setup, see “SPGU Pulse Setup Parameters” on page 7-28.
For a summary of source output operation in sweep or sampling measurement mode,
see “Pulse O
