Defines the frequency of the signal to be measured. The power sensor has a memory
with frequency-dependent correction factors. This allows extreme accuracy for signals
of a known frequency.

Selects the coupling option. The frequency can be coupled automatically to the center
frequency of the instrument or to the frequency of marker 1.

Selects the unit with which the measured power is to be displayed. Available units are
dBm, dB, W and %.
If dB or % is selected, the display is relative to the reference value that is defined with
either the "Meas -> Ref" setting or the "Reference Value" setting.

on page 901Meas Time/Average
Selects the measurement time or switches to manual averaging mode. In general,
results are more precise with longer measurement times. The following settings are
recommended for different signal types to obtain stable and precise results:
"Short"
Stationary signals with high power (> -40dBm), because they require
only a short measurement time and short measurement time provides
the highest repetition rates.
"Normal"
Signals with lower power or modulated signals
"Long"
Signals at the lower end of the measurement range (<-50 dBm) or
Signals with lower power to minimize the influence of noise
"Manual"
Manual averaging mode. The average count is set with the Average
Count (Number of Readings) setting.
