Connect the ISOVP-L in a setup as shown below. Allow a few minutes of temperature
adjustment before starting the procedure.
OFFSET Verification
.
1) Set the voltage source to 0V.
2) Measure the voltage of the voltage source with the multimeter in the mV scale.
3) Connect the voltage source to the probe head with the BNC/SMB adapter.
4) Connect the output of the ISOVP-L to the multimeter using the 50Ohm terminator and the
BNC to jack adapter.
5) Turn on the receiver and press the “Offset adjust” button in the ISOVP-L receiver before
taking each measurement.
6) Take 3 measurements and calculate the mean of all 3 offsets as follows:
Total offset error= ( abs(V
offset#1
-
) + abs(V
offset#2
-
)
+ abs(V
offset#3
-
) ) /3
