CP/ACP
CONFIG
See following section "Setting the Channel Configuration"
SET CP
REFERENCE
With channel power measurement activated, the SET CP REFERENCE softkey
defines the currently measured channel power as the reference value. The
reference value is displayed in the CH PWR REF field; the default value is 0 dBm.
In adjacent-channel power measurement with one or several carrier signals, the
power is always referenced to a transmission channel, i.e. no value is displayed
for CH PWR REF.
IEC/IEEE-bus command: POW:ACH:REF:AUTO ONCE
SWEEP
TIME
The SWEEP TIME softkey activates the entry of the sweep time. With the RMS
detector, a longer sweep time increases the stability of the measurement
results.
The function of the softkey is identical to the softkey SWEEP TIME MANUAL in
the menu BW.
IEC/IEEE-bus command: SWE:TIM <value>
NOISE CORR
ON OFF
If the NOISE CORR ON/OFF softkey is activated, the results will be corrected by
the instrument's inherent noise, which increases the dynamic range.
When the function is switched on, a reference measurement of the instrument's
inherent noise is carried out. The noise power measured is then subtracted from
the power in the channel that is being examined.
The inherent noise of the instrument depends on the selected center frequency,
resolution bandwidth and level setting. Therefore, the correction function is
disabled whenever one of these parameters is changed. A disable message is
displayed on the screen.
To enable the correction function in conjunction with the changed setting, press
the softkey once more. A new reference measurement is carried out.
IEC/IEEE-bus command: SENS:POW:NCOR ON
