ARB clock in/out
290 Series generators can use an external signal as the arbitrary
waveform clock. The 292 and 294 also include an internal system
clock generator (in addition to the individual channel clock genera-
tors). The output of this system clock can be made available to drive
external circuitry or the input of another generator.

Hold
Holds an arbitrary waveform at
its current position. A TTL low
level or switch clo sure 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.
While held the front panel MAN
TRIG key or remote command
may be used to return the wave-
form to the start. The Hold input
may be enabled independently
for each channel. Input imped-
ance is10kΩ.
Channel relationships
The channels of a multi-channel
unit can be operated entirely
independently, as if they were
separate generators. The “copy”
key allows the settings of any
channel to be instantly copied to
another when required.
relationships of modulation,
summing, triggering, or phase
locking can be set up.
Multi channel sweep
Any number of channels may be
swept simultaneously. Amplitude,
Offset and Waveform can be set
independently for each channel.
For 280 Series units, the sweep
parameters will be the same
for all channels. For 290 Series
units,the sweep parameters can
be set independently for each
channel.
Alternatively, inter-channel
ARB clock out
See ARB clock In/Out within INPUTS section.
Cursor/marker out (280 Series units only)
Adjustable output pulse for use as a marker in
sweep mode or as a cursor in arbitrary wave-
form editing mode. Can be used to modulate the
Z axis of an oscilloscope or be displayed on a
second ‘scope channel.
System clock (292/294 only)
The 292/294 units incorporate an additional
frequency generator, which can be used as a
clock source for multi-channel arbitrary wave-
forms and as an auxiliary output.
The output of the system clock is available as a
1 volt pk-pk sinewave at the Auxiliary Sine Out
socket, and as a logic level squarewave at the
Ext. ARB In/Out socket.
multi-channel arbitrary waveforms, the system
clock provides an independent fixed amplitude
sine or square output which is additional to the
two or four main channel outputs.

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 num ber of channels may be
Modulated (AM or SCM) with the signal at the MODULA TION
input socket.
Inter-channel analog summing
Waveform Summing sums the waveform from any channel into
the next channel. Alternatively any number of channels may be
summed with the signal at the SUM input socket.
