R&S ESCI Receiver - TRACE
1166.6004.12 4.63 E-2
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.
The measurement detector for the individual display modes can be selected directly by the user.
The default setting is trace 1 in the overwrite mode (CLEAR / WRITE) and detector MAX PEAK is
selected, trace 2 is also in the overwrite mode (CLEAR / WRITE) and detector AVERAGE is selected,
trace 3 is 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, i.e. the trace is overwritten by each sweep.
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.
his is especially useful with modulated or impulsive signals. The signal
spectrum is filled up upon each scan 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
VIEW
The VIEW softkey freezes the current contents of the trace memory and
displays it.
If in the VIEW display mode the level display range (GRID RANGE) or the
reference level (GRID MIN LEVEL) are changed, R&S ESCI automatically
adapts the measured data to the changed display range. This allows an
amplitude zoom to be made after the measurement in order to show details
of the trace.
