Performance Verification
Performance Verification
The purpose of the electrical test is to verify the response of the HSB
option card in the ESA. The HSB option card provides an output
frequency range from 2.1 GHz to 3.1 GHz with a power level
≥
5 dBm.
Equipment Required
•
Spectrum Analyzer. Use a spectrum analyzer with a frequency
range of > 4 GHz.
•
ESA Spectrum Analyzer containing Option HSB (DUT).
•
RF Cable (3.5 mm).
1.
Turn on both spectrum analyzers and press
[Preset]
.
2. Turn off the Auto Align function of the DUT and the test spectrum
analyzer, if so equipped.
3. Connect the HSB Output, on the rear of the ESA DUT, to the RF
Input, on the spectrum analyzer using an RF cable and adapter, if
required.
4. Press
[Frequency]
on the ESA DUT and set the start frequency to
0 Hz and the stop frequency to 1.1 GHz.
5. Press
[Frequency]
on the test spectrum analyzer and set the start
frequency to 1.7 GHz and the stop frequency to 3.3 GHz.
6. Set the RF level on the test spectrum analyzer to 30 dBm.
7. Increase the test spectrum analyzer sweep time to approximately
20 seconds for improved display clarity.
8. Leave all other ESA DUT and test spectrum analyzer settings
autocoupled.
9. Set the test spectrum analyzer markers 1 and 2 to frequencies of
2.1 GHz to 3.1 GHz, respectively.
10. Press
[View Trace]
>
Max Hold
on the test spectrum analyzer.
