change the output connection to the monitor connector. note that the waveform 
timing does not change, but that the pulse amplitude more than doubles. 

change the output connection to the +VAriABle connector. Again note, that the 
timing remains the same, but the amplitude drops to the previously set +5 volts. Vary 
the AmPlitude dial and notice how the amplitude follows the value on the dial. 
switch the AmPlitude to Pulsed xV and the signal amplitude drops to /0 of the 
previously observed value. switch the AmPlitude to dc xV and the output changes 
to a steady voltage, which can still be varied with the AmPlitude dial. switch 
AmPlitude to dc x0V and the output voltage increases ten-fold.

change the output connection to the -VAriABle connector. repeat the steps of the 
previous paragraph and note that all the output conditions remain the same except 
that all the output voltages are negative.

switch the inPut mode to eXt sYnc, then to sinGle eVent. in both modes the 
output signal goes to zero volts. Press the sinGle eVent button and note that a 
single event interval is generated from the output. switch to eXt GAtes. the output 
should still be zero. short circuit the eXt GAtes sWitcH connector and note that 
as long as the connection is held, the output produces waveforms. As soon as the 
connection is broken, the output returns to zero. the eXt sYnc and the eXt GAtes 
VoltAGe input modes can be verified by applying the appropriate signal to the 
connectors. For each eXt sYnc pulse, one event interval is generated. As long as the 
eXt GAtes VoltAGe is applied, the output will produce waveforms.
