discussed here and ensure any connected oscillo-
scopes will meet the voltage limits.
To use the probe, simply connect the MCX connector into
the ChipSHOUTER front connection. There are two front con-
nections: a “voltage” monitor, and a “current” monitor.
The voltage monitor provides a 20:1 attenuation, so us-
ing this means setting your oscilloscope up with a 20:1
attenuation rating. Note that at a peak 500V pulse voltage,
the 20:1 attenuation means your oscilloscope front-end will
see 25V at the 1MΩ input.
CAUTION: Confirm your oscilloscope 1MΩ maximum
voltage rating is at least 25V. Due to ringing at
the tip voltages may exceed 500V, so a ±30V rating
is recommended. NewAE Technology Inc. cannot ac-
cept any liability for damage to your oscilloscope
or other connected equipment, and you use this
monitor at your own risk.
The current monitor provides a 10:1 attenuation, but
this is not a calibrated current monitoring output. Instead
it is used to provide general information on pulse shape.
The current is monitored across a pulse-tolerant thick-
film resistor. This resistor is used as part of the current
limiting and back e.m.f. absorption circuit.
