LN Preamp - Activates Low Noise Preamplifier
Activates or deactivates the low noise preamplifer if option R&S ESU-B24 is
installed.
The low noise preamplifier provides the maximum sensitivity of the R&S ESU. Since
the low noise preamplifier is in front of the preselection filters the risk of intermodula-
tion is increased. This preamplifier covers the range from 100 kHz to the upper limit
frequency. Activating the low noise preamplifier deactivates the standard preampli-
fier.
As of firmware version 4.43 ist is possible to activate the low noise preamplifier in
combination with an active preselector.
Default value is OFF.
Remote command:
INP:GAIN:LNA:STAT ON | OFF

softkey shifts the active scan range in the table to the right
