Troubleshooting the 0 to 36 MHz baseband signal path
Troubleshooting the 0 to 36 MHz baseband signal path
Perform the following procedures in the order listed to troubleshoot the 89640
baseband signal path.
This test requires a signal generator. See
"Recommended Test Equipment" (page
.
1. Set up the 896xxA 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 > 0 - 36 MHz.
e. Disconnect the BNC cable from the E1439
Analog In
connector and
connect a signal generator to E1439
Analog In
.
f. Set the signal generator for 20 MHz, -30 dBm output.
g. Set the marker to peak by right clicking on the spectrum trace and clicking
↑
Peak
.
h. The marker reading should be 20 dBm ± 1.7 dB.
If this reading is incorrect, the E1439 module is most likely faulty.
2. Connect the signal generator output to 89605
Ch 1 Input
.
a. Reconnect the BNC cable from 89605
To ADC
to E1439
Analog In
.
b. Set the center frequency to 20 MHz and the frequency span to 100 kHz.
c. Set the marker to peak by right clicking on the spectrum trace and clicking
↑
Peak
.
d. The marker reading should be -30 dBm ± 3.5 dB.
e. Change the 89640A input range in 5 dB steps while verifying that the
marker reading at each step is -30 dBm ± 3.5 dB.
If any of these readings are incorrect, the 89605 module is most likely
faulty.
3. Repeat steps 1 and 2 for a second channel if required.
