Configuration/Setup
ESIB
Preamplification and Preselection
In the frequency range up to 7 GHz, ESIB has a preselection with switchable preamplifier which can be
selected by the user in the analyzer mode. The preselection is always active in the receiver mode.
Option ESIB-B2, Preamplification, extends the frequency range for preamplification to 26.5 GHz or
40 GHz.
The 20 dB preamplifier is available only if the preselection is switched on.
Preselection
The frequency range 20 Hz to 7 GHz is distributed over nine filter bands. Two fixed-tuned filters are
used up to 2.025 MHz, six tracking passband filters from 2.025 to 1000 MHz and a fixed-tuned highpass
filter above 1 GHz.
The filters are switched by a relay at 150 kHz and by PIN-diode switches above 150 kHz.
