How to select a NA Measurement
 Press Measure 1.
 Then choose from the following:
NOTE The A and R1 receiver 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 does NOT indicate the actual power levels
out of the source port. The actual power level is close to the typical output power of
+5 dBm (High power) and -25 dBm (Low power).

Parameter Conversion
In NA Mode ONLY, converts the active S-parameter trace to an equivalent
impedance (Z), admittance (Y), or reciprocal 1/S-parameter.
