Setting the Peak Output Voltage
Select the desired output using the Output switch (if apply,
Figure 6
item 11). Adjust the output
voltage setting using the Voltage adjust knob (
Figure 6
item 1) to the voltage specified in
Table 4
.
Note that the front panel meter reads the voltage of C1. Depending on the waveshaping network
that is selected, this voltage will be higher than the peak voltage of the output waveform.
CAUTION: DO NOT SET THE VOLTAGE ABOVE THE MAXIMUM VOLTAGE
SETTING SPECIFIED IN Table 4. DOING SO MAY DAMAGE THE EQUIPMENT

Output Voltage Setting.
1. Note that the tolerance on the peak output voltage is +0, -10%. Therefore the center of this
tolerance band is -5%, corresponding to 950V, 4750V, 11400V for the 1000V, 5000V, and
12000V settings respectively.
2. Multiple output if apply, otherwise single one.
