Messages Beginning with Variables<filename> file not found
The file indicated could not be found at the listed system mass storage file location. Check
the filename and the system mass storage file location.
<keyboard entry> is a non-numeric entry
The program expected a numeric entry but did not receive one. Enter a numeric entry.
<number of instruments> instruments have HP-IB addresses of <HP-IB address>
The indicated number of instruments have all been set to the same HP-IB address. Review
the addresses and eliminate the duplication.
<power meter model number> doesn’t read signal to be in -1 +/-5
dBm
range
The power meter (or measuring receiver) does not read a power level within the range
indicated. Check for loose connections.
<source model number> signal not in
+5
+/-5
dBm
range
The source indicated was set for
+5
dBm
output, but the spectrum analyzer measured the
amplitude to be outside the
f5
dB range. Check test setup.
<source model number> signal not in -1
+/-5
dBm
range
The source indicated was set for + 5
dBm
output and the source output is fed through a
power splitter to the spectrum analyzer under test. The spectrum analyzer should measure
the amplitude to be within 5 dB of -1
dBm
(6 dB loss through power splitter). Check test
setup.
<source model number> +lO
dBm
signal not in + 10
+/-8
dBm
range
The source indicated was set for a
+lO
dBm
output and the source output is fed through a
low-pass filter(s) to the spectrum analyzer under test. The spectrum analyzer should measure
the amplitude to be within 8 dB of
+lO
dBm
(the filters have some insertion loss). Check test
setup.
<source model number> has a cold oven
The 10 MHz reference oven oscillator has not warmed up yet. Allow the oven to warm up.
<source model number> is unlevelled
The source indicated has been programmed for an amplitude which results in an unlevelled
condition. Check the test setup for loose connections.
