R&S SGT100A
Attenuates the level of the internal, digitally modulated I/Q baseband signals, and thus
the level of the RF signal accordingly.
The function allows fast level changes of the internal I/Q signals, but it has no effect on
externally provided I/Q signals.
Note: If you specify a digital attenuation value, the R&S SGT still shows the level as
set with
played, but the level at the RF signal output is higher or lower according to the digital
attenuation.
Remote command:
[:SOURce]:POWer:ATTenuation:DIGital
Offset
Sets a level offset.
This value represents the level shift of a downstream instrument, as for example an
attenuator or an amplifier, and is indicated in the status bar of the display. It does not
change the level at the RF output.
Remote command:
[:SOURce]:POWer[:LEVel][:IMMediate]:OFFSet
Mode
Allows you to optimize the RF output signal for applications, where improved harmonic
distortion or improved wideband noise is required.

Setting Characteristic
Selects the characteristic for the level setting. For some general applications, the
instrument operation can be optimized by selecting one of the predefined level setting
characteristics.

In normal mode, the generator provides an RF output signal with high
signal to noise ratio and low distortion, according to the data sheet.
This setting forces the generator to further optimize the signal to
noise ratio.
In this mode, the generator reduces distortions of the RF signal to a
minimum.

The instrument provides the highest dynamic range and the fastest
setting times according to the data sheet.
The RF signal is shortly blanked during the moment the step attenua-
tor is switched on.
Suppresses level blanking at frequency and level changes.
This mode reduces the dynamic range of the instrument. The step
attenuator is fixed.
