Step 5 : Connecting DUT and Reading Measurement Results
An error message appears when no DUT is connected. When the DUT
is connected to the fixture, the HP E4915A/E4916A starts searching
for the resonance point and then displays the resonant frequency and
Cl.

If an Error Message Appears When DUT Is Connected
If an error message appears when the DUT is connected, the DUT
resonant frequency may not be found within the specified frequency
range or calibrations may not have been correctly performed. Check
your measurement according to the following guidelines. For more
information on each error message, refer to HP E4915A/E4916A
Operation Manual.
■ Check that both CL adapter boards (supplied with the HP 41902A)
are mounted.
If no CL adapter board or only one of these boards is mounted,
mount both of them.
■ Check that the nominal DUT resonant frequency matches the
frequency you have specified.
If these frequencies do not match, repeat the procedure from
step 4.
