Operating Manual EMI TEST RECEIVER ESIB7 - Rohde & Schwarz

ESIB
Receiver - Frequency and Span
Frequency and Span Selection – FREQUENCY Key Group
The FREQUENCY key group is used to specify the receiver frequency and the frequency axis of the
active measurement . The frequency axis is defined by the start and stop frequency.
After pressing one of the keys FREQ, START or STOP, the value of the corresponding parameter can
be defined in the appropriate dialog window.

The START key opens a window where the start frequency of the scan
diagram can be entered.
The start frequency can be selected in the ESIB frequency range
irrespective of scan range limits.

The STOP key opens a window where the stop frequency of the scan
diagram can be entered.
The stop frequency can be selected in the ESIB frequency range
irrespective of scan range limits.
The permissible value range for the stop frequency is:
f stop > f start

The FREQ key opens a window where the receiver frequency can be
entered.
A precondition is that the frequency and level readout is active.
The permissible value range depends on the selected input:
Input 1: 20 Hz ≤ f in ≤ f max
Input 2: 20 Hz ≤ f in ≤ 1 GHz
If 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.
