Remote command:

[SENSe:]PMETer:FREQuency:LINK on page 796

Unit/Scale

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.

Remote command:

Meas 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.

Setting the Reference Level from the Measurement Meas -> Ref

Sets the currently measured power as a reference value for the relative display. The

reference value can also be set manually via the Reference Value setting.

Remote command:

CALCulate<n>:PMETer:RELative[:MAGNitude]:AUTO ONCE on page 794

Reference Value

Defines the reference value in dBm used for relative power meter measurements.

Remote command:

CALCulate<n>:PMETer:RELative[:MAGNitude] on page 794

Use Ref Level Offset

If activated, takes the reference level offset defined for the analyzer into account for the

measured power (see "Shifting the Display (Offset)" on page 311).

If deactivated, takes the Sensor Level Offset into account.
