Auxiliary Input Correction, Adjustment #111 RF Network Analyzers
2-14 Service Guide
Auxiliary Input Correction, Adjustment #111
This adjustment generates correction constants for the auxiliary input. The analyzer
computes the offset and gain of the auxiliary input circuitry by measuring two voltages
(0 and +10.000 DC volts) that are applied to the auxiliary input.
Required Equipment
NOTE The voltage reference source provides +10 V at its BNC connector. This
connector must be connected to the AUX input on the rear panel of the
analyzer.
Warmup Time
Allow the analyzer to warm up for one hour.
Estimated Adjustment Time
This adjustment takes approximately one minute to perform.
Procedure
1. Press
.
2. This is a fully automated adjustment handled by the internal firmware. Follow the
instructions on the analyzer's display.
3. If you are not going to make any more adjustments, press
.
If you are going to make more adjustments, save the correction constant data that you
have generated so far.
a. Insert a formatted disk into the internal disk drive.
b. Press .
This creates a file (or writes over an existing file) where the correction constants are
stored.
1. Cable 8120-5514 must be used with the voltage reference source box; the normal power
sensor cable will not work. (This cable is included as a part of 08712-60031.)
