Operating Manual EMI TEST RECEIVER ESIB7 - Rohde & Schwarz

ESIB
Receiver - Traces
VIEW
The VIEW softkey freezes the current contents of the trace memory and
displays them.
If, in the VIEW display mode, the level display range (LEVEL RANGE) is
changed, the ESIB 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.
IEC\IEEE bus command
:DISPlay[:WINDow]:TRACe:MODE VIEW
BLANK
The BLANK softkey removes the trace from the display screen. However, the
trace data remain stored in memory and can be displayed again by VIEW.
The markers for the blanked trace are also erased. If the trace is activated
again (with VIEW, CLEAR / WRITE, MAX HOLD, MIN HOLD) the markers
will be restored to their original positions.
IEC\IEEE bus command
:DISPlay[:WINDow]:TRACe OFF
MAX HOLD
The MAX HOLD softkey activates the max hold function.
In this display mode, the ESIB saves for each scan the largest of the
previously stored/currently measured values in the trace memory. In this way,
the maximum value of a signal can be determined over several scans.
This is especially useful for measurement of modulated or pulse-like signals.
The signal spectrum is built up scan by scan until all the signal components
have been captured.
IEC\IEEE bus command
:DISPlay[:WINDow]:TRACe:MODE MAXH
MIN HOLD
The MIN HOLD softkey activates the min hold mode.
In this display mode, the ESIB saves for each scan the smallest of the
previously stored/currently measured values in the trace memory. In this way,
the minimum value of a signal can be determined over several scans.
This function is, e.g., useful in making an unmodulated carrier in a mix of
signals visible. Noise, interference signals or modulated signals are
suppressed by the MIN HOLD function while a CW signal maintains a
constant level.
IEC\IEEE bus command
:DISPlay[:WINDow]:TRACe:MODE MINH
FINAL
RESULTS
(only traces 3 and 4)
The FINAL RESULTS softkey activates the display of final measurement
values. Trace 3 represents the allocated final measurement values referring
to trace 1 with the symbol "x" and trace 4 the final measurement values for
trace 2 with "+" (see section "Selection of Detectors for Final Measurement").
