HP 41802A, Operation Note, Page: 21 / 50

Maximum Allowable Level
Caution
Maximum allowable level (ac+dc) to the probe is 650 V .
Discharging the Probe
Caution
Measuring a node having a dc voltage potential charges the blocking capacitors
inside the HP 41802A. Ground the probe pin after measuring such nodes to
discharge probe capacitor . F ailure to do this could result in damage to sensitive
circuits in the DUT , especially if it is an active device .
Probe P ower Plug
Note
Connect the probe power plug, before connecting the N-type connector .
Preparation for Use
This paragraph provides the HP 41802A operating check procedure and the probe adjustment
procedure .
The HP 41802A operating check procedure checks the adapter gain using a network analyzer ,
a spectrum analyzer , or a network/spectrum analyzer . These operating check procedures are
only intended to ensure that the HP 41802A is functional. If the HP 41802A fails this check,
it should be repaired. T o verify that the HP 41802A meets its specications , perform the
performance test described in Chapter 4.
The probe adjustment procedure is for frequency compensation. F or the best measurement
results , always adjust the probe .
