4.2 R&S ESU Initial Configuration – PRESET Key
PRESET Using the PRESET key, the R&S ESU can be set to a predefined initial state.
Two predefined initial states can be selected in the SETUP side menu. For details
on the preset mode refer to section “Instrument Setup and Interface Configuration –
SETUP Key” , “PRESET RECEIVER” on page 4.297 and “PRESET ANALYZER” on
page 4.297 .
Pressing the PRESET key causes the R&S ESU to enter its initial state according to
one of the following tables:
The settings are selected in a way that the RF input is always protected against
overload, provided that the applied signal levels are in the allowed range for the
instrument.
The initial instrument state set by the PRESET key can be adapted to arbitrary
applications using the STARTUP RECALL function. With this function the STAR-
TUP RECALL data set is loaded upon pressing the
PRESET key. For further infor-
mation refer to section “Saving and Recalling Data Sets – FILE Key” on
