Troubleshooting the 6.0 GHz RF signal path
Troubleshooting the 6.0 GHz RF signal path
The following procedures direct you through inserting a signal at various points in
the analyzer’s signal path to isolate problems to a specific module. Perform the
steps in the order listed. This test requires a signal generator. See
To troubleshoot the 6.0 GHz RF signal path:
1. Set up the analyzer as follows:
a. If it is not already running, start the Vector Signal Analyzer by double
clicking the icon or clicking
Start > (All) Programs > Agilent 89600 VSA
> Vector Signal Analyzer
.
b. Click
File > Preset > Preset Setup.
c. Click
Utilities > Calibration,
and clear the
Apply Corrections to Data
checkbox.
d. Click
MeasSetup > Frequency Bands > 36 MHz
–
6 GHz
.
e. Disconnect the BNC cable from the E1439
Analog In
connector and
connect a signal generator to E1439 Analog Input.
f. Set the signal generator for 70 MHz, –10 dBm output.
g. Set the analyzer’s marker to peak by right clicking on the spectrum trace
and clicking
↑
Peak
. The marker reading should be 20 dBm ± 1.5 dB
h. Verify the other settings in the following table.
If any of the readings are incorrect, the E1439 module is most likely faulty.
2. Reconnect the BNC cable to the E1439
Analog In
and disconnect the SMA
cable from the 89605
From 70 MHz IF Out
connector. Connect the signal
generator output to 89605
From 70 MHz IF Out
.
a. Set the marker to peak by right clicking on the spectrum trace and clicking
↑
Peak
.
b. The marker reading should be –40 dBm ± 1.5 dB.
If this reading is incorrect, the 89605 module is most likely faulty.
