1.4.6 Outputs
ARB Out (50R)
Source of primary waveform output. Maximum
amplitude is
+
5 Vp into 50R. Output is fuse protected.
Sync Out (TTL)
Will drive up to 10 LSTTL loads.This is a pulse 1 sample
time wide that is usually used to sync an oscilloscope
or another ARB generator. Pulse position is adjustable
to any point in the waveform.
Burst Done Out (TTL)
Will drive up to 10 LSTrL loads. ATTL low indicates that
the waveform is running. TTL high indicates that the
instrument is waiting for a trigger in triggered, gated,
toggle, or burst modes. Used primarily to start another
ARB generator in series operation.
Ref Out (TTL)
Will drive up to 10 LSTTL loads. This pulse train at the
sample frequency is used primarily as a reference
source for other ARB generators in series operation or
in parallel operation.
Hold In
Impedance is 100 KR. ATTL low or switch closure at this
input causes the generator to stop at the current output
level and remain there until released by a TTL high or
switch opening.
Return In
Impedance is 100 KR. ATTLlowor switch closureat this
input causes the output level to ramp back to the start
value. ' T he ramp rate is front panel selectable from 0 to
100 ms per point.
1.4.8 Trigger Sources
Manual
Use the Trigger pushbutton switch on front panel to
operate internal trigger circuitry. The slope polarity can
be set via the display menus.
External
Use the communication ports(GPIB or RS-232C)or the
Trig In connector on front panel. Trig In connector fre-
quency input can be up to 1 MHz. The slope polaritycan
be set via the display menus.
