Active Adjustment Data
Displays whether the factory or user defined (custom) calibration value is used for the
external calibration of the reference oscillator.
Adjusting the calibration value for the OCXO adjustments is a protected service proce-
dure that requires a Protection Level 2 password. The exact test procedure is descri-
bed in the service manual.
See also Chapter 10.13, "External adjustments", on page 158.
Adjustment Active
Available only for "Source > Int".
Selects adjustment mode.
"OFF"
Uses the calibrated internal reference frequency. This value is deter-
mined at one of the R&S service centers during calibration.
"ON"
A user-defined adjustment value is used. The value is entered under
DAC Value.
User-defined values allow you to set the impaired frequency freely, for
example, to simulate a frequency error.
The instrument is no longer in the calibrated state. However, the cali-
bration value is not changed and the instrument resumes the calibra-
ted state after switching the "Adjustment State" to Off.
Remote command:
[:SOURce]:ROSCillator[:INTernal]:ADJust[:STATe] on page 284
DAC Value
Enters a user-defined adjustment value for the internal reference frequency. This value
is not used unless "Adjustment Active > On" is selected.
"DAC Value = 0" indicates the calibrated state. The setting range depends on the refer-
ence oscillator type and its factory calibration value.
Remote command:
[:SOURce]:ROSCillator[:INTernal]:ADJust:VALue on page 283
9.5 Level and power-on settings
This section explains the level settings of the R&S SGS. The instrument can be equip-
ped optionally with an active electronic step attenuator (R&S SGS-B26).
Configuring RF level
► To change the RF level of the selected instrument, perform one of the following:
a) Select "SGMA-GUI main panel > Level".
b) Select "SGMA-GUI > Instrument Name > Level > RF Level > Level".
Changes of the RF level have an immediate effect on the output signal.
