R&S ESU Instrument Functions
Analyzer Mode
SELECT
TRACE The SELECT TRACE softkey activates the entry for the active trace (1, 2, 3).
Remote command:
--
(selected via numeric suffix of:
TRACe
)
CLEAR/WRITE The CLEAR/WRITE softkey activates the overwrite mode for the collected mea-
sured values, i.e. the trace is overwritten by each sweep.
In the CLEAR/WRITE display mode all the available detectors can be selected. In
the default mode the autopeak detector (setting AUTO ) is selected.
Each time the CLEAR/WRITE softkey is actuated, R&S ESU clears the selected
trace memory and starts the measurement anew.
Remote command:
DISP:WIND:TRAC:MODE WRIT
MAX HOLD The MAX HOLD softkey activates the max peak detector.
The R&S ESU saves the sweep result in the trace memory only if the new value is
greater than the previous one.
The detector is automatically set to MAX PEAK . The maximum value of a signal can
thus be determined over several sweeps.
This is especially useful with modulated or impulsive signals. The signal spectrum is
filled up upon each sweep until all signal components are detected in a kind of enve-
lope.
Pressing the MAX HOLD softkey again clears the trace memory and restarts the
max hold mode.
Remote command:
DISP:WIND:TRAC:MODE MAXH
AVERAGE The AVERAGE softkey activates the trace averaging function. The average is
formed over several sweeps. Averaging can be performed with any of the detectors
available. If the detector is automatically selected by R&S ESU, the sample detector
is used.
Depending on the setting of AVG MODE, the logarithmic level values or the mea-
sured power/voltage values are averaged.
Averaging is restarted every time the AVERAGE softkey is pressed. The trace mem-
ory is always cleared.
Remote command:
DISP:WIND:TRAC:MODE AVER
