Adjusting for Oscilloscope Setting
You will need to adjust the probe for your specific oscillo-
scope. This can be done by adjusting the small compensation
trimmer that is located on the BNC body (see Figure 11).

The most effective calibration would be performed by at-
taching a resistive load to the SMA connector output, and
observing the voltage with an externally calibrated oscillo-
scope probe on this resistor. Doing so requires exposing
high voltages and is not covered by this manual.
Instead we present a simple calibration that should work
for most users. For calibration the 4mm injection tip should
be connected to the ChipSHOUTER and the pulse output should
be set to simple mode with a pulse width of 80 (ns), a dead-
time of 10 (ms) and a voltage of 400v. This process is made
easier by setting pulse repeats to a high number (100 works
well) and using the average mode on your oscilloscope with a
