Traces - Analyzer R&S ESCI
1166.6004.12 4.104 E-1
The TRACE key opens a menu offering the setting options for the selected trace.
In this menu, the mode of representing the measured data in the frequency or time domain in the 501
pixels of the display is determined. Upon start of the measurement, each trace can be displayed either
completely new or based on the previous results.
Traces can be displayed, blanked and copied. Traces can also be corrected with the aid of
mathematical functions.
The measurement detector for the individual display modes can be selected directly by the user or set
automatically by R&S ESCI.
The default setting is trace 1 in the overwrite mode (CLEAR / WRITE), the other traces 2 and 3 are
switched off (BLANK).
The CLEAR/WRITE, MAX HOLD, MIN HOLD, AVERAGE, VIEW and BLANK softkeys are mutually
exclusive selection keys.
SELECT
TRACE
The SELECT TRACE softkey activates the entry for the active trace (1, 2, 3).
IEC/IEEE-bus command -- (selected via numeric suffix of :TRACe)
CLEAR/
WRITE
The CLEAR/WRITE softkey activates the overwrite mode for the collected
measured values, ie 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 ESCI clears the
selected trace memory and starts the measurement anew.
IEC/IEEE-bus command DISP:WIND:TRAC:MODE WRIT
MAX HOLD
The MAX HOLD softkey activates the max peak detector.
R&S ESCI 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 envelope.
Pressing the MAX HOLD softkey again clears the trace memory and restarts
the max hold mode.
IEC/IEEE-bus command DISP:WIND:TRAC:MODE MAXH
