Performance Quick Check
Verifying your Electrical Calibration
32
Passing this test ensures that the electrical calibration is within
expected performance.
1. Follow the steps in the sections "Preparation " on page 30
and "Network analyzer settings and electrical calibration" on
page 30.
2. Connect the 85054-60037 "type-N female to female adapter"
(provided with the 85092C option 00A ECAL kit) between the
two 8120-8862 "type-N test port cables" supplied with the
LCA.
3. Press the [Macro Setup] key on the front panel of the network
analyszer, then select
4. Click
to start the LCA measurement setup.
5. Select the EE Measurement tab.
6. Click
.
7. Make a corrected measurement with the network analyzer.
8. Inspect the results.
• Electrical return loss S11 should be similar to S22.
• Both curves should be below -20dB over the full
measurement range, with only low frequency dependence
on applied modulation frequency.
• Transmission loss S12 should be similar to S21.
• Both curves should be within +0.1dB to -0.6dB over the
full measurement range, with only low frequency
dependence on applied modulation frequency.
If the results differ from the expected values
• Visually inspect the electrical connectors on the "Electronic
Calibration Modules" and the .
If an electrical connector seems to be damaged, contact
Keysight for repair or replacement.
• Clean the electrical connectors on the "Electronic Calibration
Modules" and the "Flexible Cables for Test Ports.
If an electrical connector seems to be damaged, contact
Keysight for repair or replacement.
