Probe Adjustment
This procedure adjust the high-frequency and low-frequency paths on the 1141A
Differential Probe.
NOTE Do not perform this procedure as a part of routine maintenance. Perform the procedure
only if the probe does not meet specifications or has been repaired.
CAUTION You are going to remove the covers of the probe, so the assembly inside will be exposed
while under power. The PC assembly will be electrically and mechanically vulnerable.
Do these adjustment procedures in an ESD-safe area.
Avoid inadvertent contact between the powered assembly and nearby tools and
equipment.
Avoid mechanical damage by carefully handling the exposed assembly and cables.
