Some instrument's functions like "Frequency" and I/Q settings are disabled.
3. Select "SGMA-GUI > Instrument Name > Level > RF Level" and adjust the level of
the output signal.
4. Set "SGMA-GUI > RF > On" or press the [RF ON] key on the front panel of the
instrument to enable the output of the generated signal at the RF connector.
The [RF ON] key is green.
The fed signal is amplified with the selected value and output at the RF connector
of the instrument.
9.4 How to Configure the Reference Oscillator Source
To use the internal reference frequency source
1. To enable the instrument to use its internal reference frequency source, perform
one of the following:
a) Select "SGMA-GUI main panel > Ext Ref Off ".
b) Select "SGMA-GUI > Instrument Name > Reference Oscillator > Source > Int".
2. In the "Reference Oscillator" dialog, set the "REF/LO Out > REF".
The "Output Frequency" can be configured to either 10 MHz or 1 GHz.
The instrument uses the internal reference signal. The [REF EXT] LED at the front
panel of the instrument is off.
To output the reference frequency (internal or external) at the REF/LO OUT connector
of the instrument, select "Reference Oscillator > REF/LO Output > REF".
To use an external reference frequency source
To improve measurement accuracy, it is advisable to provide an external reference fre-
quency to all the instruments in the test setup or to distribute the internal reference sig-
nal of the signal generator to the remaining instruments.
1. Provide the signal of an external reference frequency source to the REF/LO IN
connector of the instrument.
2. To enable the instrument to use the external reference frequency source, perform
one of the following:
a) Select "SGMA-GUI main panel > REF > Ext Ref On ".
b) Select "SGMA-GUI > Instrument Name > Reference Oscillator > Source > Ext".
