Preamplification and Preselection

In the frequency range up to 3.6 GHz, R&S ESU offers a preselection with switch-
able preamplifier which can be selected by the user in the analyzer mode. The pre-
selection is always active in the receiver mode.

The 20 dB preamplifier is available only if the preselection is switched on.

Preselection

The frequency range 20 Hz to 3.6 GHz is distributed over 12 filter bands.

Two fixed-tuned filters are used up to 2 MHz, eight tracking passband and high-pass
filters from 2 MHz to 2000 MHz and two fixed-tuned high-pass filter above 2 GHz.

The filters are switched by a relay at 150 kHz and by PIN-diode switches above
150 kHz.

Fig. 4.17 Preselection and preamplifier

PRESELECT
ON/OFF

The

PRESELECT ON/OFF

softkey switches the preselection on or off.

The softkey is available only in the analyzer mode.

Remote command:

INP:PRES ON

Preselection causes additional dependencies which are automatically taken into
account in the coupled setting.

• With the preselection active, the FFT bandwidths are not available.
