Operating Manual EMI TEST RECEIVER ESIB7 - Rohde & Schwarz

ESIB- Receiver
ESIB
A frequency scan can be performed after setting the start and stop frequency and the step width. The
scan subranges can be defined in a table (DEFINE SCAN softkey). The entry of standard-conformal
frequency ranges and associated receiver settings are facilitated by default settings (softkeys CISPR
RANGE A...D).
The scan is started with the SCAN softkey or the RUN key in the SWEEP field.
To reduce the amount of data in RFI voltage measurements, a list of subrange maxima (softkey PEAK
LIST) can be generated from the scan results and an acceptance line (softkey MARGIN) may be
defined. A final measurement is performed only for frequencies with high RFI level.
The final measurement may be either automatic (softkey AUTOMATIC FINAL) or in interactive mode
(softkey INTERACTIVE). Automatic control functions for line impedance stabilization networks (softkey
LISN) are available. The final measurement is started with the softkey RUN FINAL MEAS.
The measurement examples given in section 2 serve as introduction into the different fields of
application of the EMI test receiver.
When the EMI receiver mode is active, the MODE key directly opens the main receiver menu. For a
change to the ANALYZER mode, the main menu must be called first.

FREQUENCY
The RECEIVER FREQUENCY softkey activates the entry field of the receive
frequency.
The receive frequency can also be activated with the FREQ key in the
FREQUENCY field without quitting the currently selected menu. A precondition is
that the frequency and level display is active.
The adjustable frequency range depends on the selected input:
Input 1: 20 Hz ≤ f in ≤ f max
Input 2: 20 Hz ≤ f in ≤ 1 GHz
When the tuning frequency is lower than twice the IF bandwidth, the IF bandwidth
is automatically reduced so that this condition is met again.
If the frequency is increased again, the original IF bandwidth is restored. The
memory is cleared when the IF bandwidth is manually changed.
The resolution of the receive frequency is always 0.1 Hz.
