R&S ESU Instrument Functions
Analyzer Mode
STOP LIMIT The STOP LIMIT softkey activates the entry of the upper limit of the evaluation
range.
Remote command: CALC:MARK:X:SLIM:RIGH <value>
SET
REFERENCE
The SET REFERENCE softkey sets the power values currently measured as refer-
ence values for the calculation of the mean value (MEAN) and the rms value (RMS).
The reference values are used to perform relative measurements.
If the calculation of the mean value (MEAN) and rms value (RMS) is not switched
on, 0 dBm is used as a reference value.
If the average value (AVERAGE) or maximum value (MAX HOLD) is calculated over
several sweeps, the current value is the measured value summed up at the actual
time.
Remote command: CALC:MARK:FUNC:SUMM:REF:AUTO ONCE
POWER
ABS | REL
The POWER ABS/REL softkey selects the absolute power measurement (default
setting) or relative power measurement. The reference value for the relative power
is defined by SET REFERENCE.
The value 0 dBm is used if the reference value is not defined.
Remote command: CALC:MARK:FUNC:SUMM:MODE ABS
MAX HOLD
ON | OFF
The MAX HOLD ON/OFF softkey switches the display of the maximum peak
obtained from measurements at successive sweeps on and off.
The displayed maximum peak is only updated at the end of a sweep if a higher
value has occurred.
The maximum value can be reset by switching the MAX HOLD ON / OFF softkey off
and on again.
Remote command: CALC:MARK:FUNC:SUMM:PHOL ON
CALC:MARK:FUNC:SUMM:PPE:PHOL:RES?
CALC:MARK:FUNC:SUMM:RMS:PHOL:RES?
CALC:MARK:FUNC:SUMM:MEAN:PHOL:RES?
CALC:MARK:FUNC:SUMM:SDEV:PHOL:RES?
AVERAGE
ON | OFF
The AVERAGE ON/OFF softkey switches averaging over successive sweep mea-
surements on and off.
The measured values can be reset by switching the AVERAGE ON / OFF softkey off
and on again.
Remote command: CALC:MARK:FUNC:SUMM:AVER ON
CALC:MARK:FUNC:SUMM:PPE:AVER:RES?
CALC:MARK:FUNC:SUMM:RMS:AVER:RES?
CALC:MARK:FUNC:SUMM:MEAN:AVER:RES?
