8.3.2.4 Storing and Loading Instrument Settings
Settings and measured data can be stored and loaded. You can define which
data set is loaded when the instrument is preset or started.
Storing Instrument Settings
In the following example, the settings/measured data to be stored are defined ini-
tially, in which case only the hardware settings are stored. However, the selection
commands for the other settings are specified with the state "OFF" for the sake of
completeness.
REM ***********************************************************************
Public Sub StoreSettings()
'This subroutine selects the settings to be stored and creates the
'data record "TEST1" in the directory C:\R_S\Instr\user. It uses the default
'setting and resets the instrument after the setting is stored.
'--------- Default settings of the R&S FSV ------------------------------
CALL SetupInstrument
CALL InstrWrite(analyzer,"INIT:CONT OFF")
'Change to single sweep
CALL InstrWrite(analyzer,"INIT;*WAI") 'Perform sweep with sync
