Power Meter (Option K9) R&S FSL
1300.2519.12 4.188 E-11
Power Meter On/Off
Switches the power measurement on or off.
Remote: PMET ON
F
requency Manual
Opens an edit dialog box to enter 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.
Remote: PMET:FREQ 1GHZ
Frequency Coupling
Opens the Frequency Coupling dialog box to select the coupling option. The frequency can be
coupled automatically to the center frequency of the instrument or to the frequency of marker 1,
or manually to a set frequency (see Frequency Manual softkey).
Remote: PMET:FREQ:LINK CENT
Unit/Scale
Opens the Unit/Scale dialog box to select the unit with which the measured power is to be
displayed.
If dB or % is selected, the display is relative to a reference value that is defined with either the
Meas–>Ref softkey or the Reference Value softkey.
Remote: UNIT:PMET:POW DBM
Remote: UNIT:PMET:POW:RAT DB
Zero
Starts zeroing of the power sensor. For details on the zeroing process refer to "To zero the
power meter" on page 4.187.
Remote: CAL:PMET:ZERO:AUTO ONCE;*WAI
Meas Time/Average
Opens the Meas Time dialog box to select the measurement time or to switch 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 of 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
Switches to manual averaging mode. The average count is set with the
Number of Readings softkey.
This parameter is available from firmware version 1.70.
