Output 

AmPlitude  ......................A ten-turn dial with an associated four-position rotary switch 

are used to control the amplitude of the signal through 
the -VAriABle and the +VAriABle output connectors. the 
number set on the dial is the actual value of the output 
voltage, depending on the full scale value selected by the 
position of the AmPlitude switch. For example, 0.00 on 
the dial and dc xV on the switch, represent a constant 
-.0V on the -VAriABle and +.0V on the +VAriABle 
outputs.

the dc positions represent a non-switching dc output 
voltage even when the other outputs are providing 
pulses. the Pulsed positions provide switched outputs, 
synchronous with the other outputs. dc outputs with the 
least amount of “noise” are obtained by switching the inPut 
mode out of continuous on and not providing an 
external input.

-VAriABle ...........................A Bnc connector used to provide a variable output signal. 

signal polarity on the center pin is negative relative to the 
connector shell.

+VAriABle .........................A Bnc connector used to provide a variable output signal. 

signal polarity on the center pin is positive relative to the 
connector shell. 

ViolAtion .........................A red light, which is illuminated for approximately one 

second, whenever the instrument is operating with timing 
parameters that are in conflict with each other. Violations 
are defined as follows: 

eVent delAY is greater than eVent interVAl. 

Pulse WidtH extends into the next eVent interVAl. 

trAin durAtion extends into the next eVent interVAl.

Pulse WidtH is greater than Pulse interVAl.
