27. Checking the Absolute Amplitude
Accuracy for Option 051
This adjustment applies to:
All 8590 E-Series spectrum analyzers, Option 051
To measure the absolute amplitude accuracy of the analyzer in the
frequency ranges 810 MHz to 956 MHz and 1429 MHz to 1501 MHz, a
signal from a synthesized sweeper is output to both the analyzer and a
measurement receiver. To determine the absolute amplitude accuracy:
1. The amplitude of the sweeper's signal is adjusted until the analyzer
marker reads out a known amplitude.
2. The amplitude of the sweeper's signal is measured by the measuring
receiver. (The measurement receiver is used as a power meter.)
3. The difference between the marker readout and the measuring
receiver's measurement is determined. This difference is the
absolute amplitude accuracy.
