Operating Manual EMI TEST RECEIVER ESIB7 - Rohde & Schwarz

ESIB
Analyzer - Traces
The TRACE keys 1...4 call a menu whith the setting options for the selected trace.
This menu is used to determine the method for compressing the measurement data in the frequency or
time domain to the 500 representable points of the display is determined.
When the measurement is started, a new trace can be displayed or the trace can be based on previous
results. The traces can be displayed, blanked and copied.
Traces can also be corrected with the mathematical functions.
The measurement detector for each of the display types may be chosen either directly or selected
automatically by the ESIB.
All activated traces are marked with a LED at the corresponding key (here, TRACE 1). The default
setting is TRACE 1 with CLEAR / WRITE selected. The remaining traces 2...4 are switched off
(BLANK). For the split screen display, the selection of the trace automatically selects the corresponding
screen for entry.
Only one of the CLEAR/WRITE, MAX HOLD, MIN HOLD, AVERAGE, VIEW and BLANK softkeys can
be activated at any one time.
CLEAR/
WRITE
The CLEAR/WRITE softkey activates the clear/write display mode.
The trace is displayed without additional trace evaluation. The trace memory
is overwritten by each sweep. If more than one data point falls within a pixel,
the trace is displayed in bar form with the maximum and minimum values
being assigned to one pixel. In the clear/write display mode, all the available
detectors are selectable. The autopeak detector is selected in the default
mode (detector to AUTO).
Whenever the CLEAR/WRITE softkey is pressed, the ESIB clears the
selected trace memory and restarts the measurement.

VIEW
The VIEW softkey freezes the current contents of the trace memory and
displays them.
If the trace data were formed through MAX HOLD, MIN HOLD or AVERAGE,
the sweep is restarted and the trace contents are cleared, after switching to
these trace modes.
If a trace is frozen by VIEW, the instrument settings can be modified without
modifying the displayed trace. The fact that the trace and the current
instrument setting do not agree anymore is indicated by an enhancement
label "*" at the right edge of the grid. The initial instrument setting can be
restored using the ADJUST TO TRACE softkey in the TRACE MATH submenu.
If LEVEL RANGE or REF LEVEL is changed in the VIEW display mode, the
ESIB adjusts the measurement data to the changed display range. Thus, an
amplitude zoom can be performed after the measurement so that details of
the trace can be seen better.
