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.
