6.12 Pattern Generator Device Commands
166
Jitter and spread spectrum clock can only be set using the N4960A serial BERT
controller clock SCPI commands. Therefore, SCPI values must be set to half of
the value desired on the pattern generator outputs.
Commands for controlling a pattern generator are preceded by :PG. However,
legacy commands preceded by :PG17 or :PG32 are supported but not
recommended.
Commands can be sent to a pattern generator currently connected to channel 0
(Jitter), channel 1 (Delay), or both. Refer to
Channelization
for information about how to send commands to the intended
pattern generator.
