Hardware Options
Option H1G, 1 GHz Analysis Bandwidth Assembly
Advanced Troubleshooting
This procedure will verify signal levels at the output of the A15 Front End
Control assembly, the IF Output of the A21 Wideband Analog IF (B2X assy), the
100 MHz reference from the A16 Reference assembly, and the rear panel IF 2
output from the H1G Analog IF assembly. Refer to
.
1.
This procedure uses an external signal source connected to the analyzer's
RF Input port.
External source settings:
Frequency: 1 GHz
Amplitude: -20 dBm
Connect the source 10 MHz Out to the signal analyzer Ext Ref, so
both instruments share a single frequency reference.
2.
UXA analyzer settings:
Mode: IQ Analyzer, Complex Spectrum
Meas Setup, IF Path, 1 GHz
Center Frequency: 1 GHz
Span: 1 GHz
Atten: 10 dB
3.
Locate the A15, Front End Control assembly in the instrument and remove
the cable from A15J901 (IF Out). Connect a signal analyzer to this J901
MMCX female connector. One way to make this connection is to order a
cable, 8121-2608 or 8121-2027 (this is the W16, SMA to MMCX cable
used in the UXA).
Set the measuring signal analyzer to the setting shown in
. The
signal amplitude at 750 MHz should be about -40 dBm as shown in
