Operating Manual EMI TEST RECEIVER ESIB7 - Rohde & Schwarz

ESIB- Receiver
ESIB
RES BW
Entry of IF bandwidth
In the case of quasi-peak weighting, usually a fixed
bandwidth is set which cannot be changed (CISPR).
However, the coupling of the IF bandwidth to the frequency
range can be cancelled using softkey QP RBW
UNCOUPLED in the MODE EMI RECEIVER menu.
Meas Time
Entry of measurement time
The measurement time can be set between 100 µs and 100
s separately for each subrange.
Auto Ranging
Activates the autorange function
With automatic attenuation setting selected, ESIB
automatically sets the input attenuation as a function of the
signal level.
Caution:
If 0 dB RF attenuation is used with
autoranging, care must be taken that the
permissible signal level at the RF input is
not exceeded. Exceeding this level would
damage the input mixer. The 0 dB
attenuation should under no circumstances
be used when RFI voltage measurements
are performed with the aid of artificial
networks as in this case very high pulses
occur during phase switching.
RF Atten
Entry of a fixed RF attenuation
Preamp
Switching the preamplifier on and off
Auto Preamp
Activates the auto preamp function
The preamplifier is considered in autoranging. It is only cut
in after the attenuation has been reduced to the minimum
settable value.
