6.4 Checking for proper operation
Narda NBM-520 49
Measures to be taken when function test is erroneous:
Repeat the test:
– move the signal source around the probe head to
generate a signal for each of the 3 spatial axes,
– monitor the display while moving the signal source.
Note: Do not use this function test for measurements. This test is
suitable only for checking probes.
All 3 channels must respond to the field source. It is no fault
if some channels display identical values.
The meaning of the channels varies depending on the type
of probe and is irrelevant for this test.
For more details about the probe, refer to the data sheet.
