Corrected measurement uncertainty, 1- or 2-port QuickCal,
high port power (default power)
Applies to N9923A with option 112, QuickCal with load, IF bandwidth = 300 Hz, no
averaging, 1-port female DUT, or 2-port female-female DUT, data based on high
port power of +5 dBm , 2-port QuickCal requires option 122, typical performance.
