Receiver Measurements; Multi-Trace Configurations - Keysight N9923A FieldFox User Manual

Receiver Measurements

In NA Mode ONLY, you can make unratioed, uncorrected receiver measurements.
These measurements are typically used as diagnostic tools for service personnel.
NOTE The receivers measurements are NOT corrected for absolute power. They are only
useful for making relative measurements. The Y-Axis and markers are labeled in dB -
NOT dBm. Specifically, R1 and R2, do NOT indicate the actual power levels out of
the source ports. The actual power levels are close to the typical output power of +6
dBm (High power) and -40 dBm (Low power).
