Hold
Holds an arbitrary waveform at its current position. A TTL low level or switch closure causes the
waveform to stop at the current position and wait until a TTL high level or switch opening which
allows the waveform to continue. The front panel MAN HOLD key or remote command may also
be used to control the Hold function. The Hold input may be enabled independently for each
channel.

INTER-CHANNEL OPERATION
Inter-channel Modulation:
The waveform from any channel may be used to Amplitude Modulate (AM) or Suppressed Carrier
Modulate (SCM) the next channel. Alternatively any number of channels may be Modulated (AM or
SCM) with the signal at the MODULATION input socket.

Used together with SYNC OUT on a master and TRIG IN on a slave
to synchronise (phase lock) two separate generators.
