Level Settings

The offset-free level, attenuation mode, level offset and level limit are set in the top section of the dialog.

RF Mode

Selects the level mode for signal output.

This function allows you, to optimize the RF output signal for applications, where improved harmonic suppression or a low Signal-to-Noise ratio is required.

Note: The modes "Low Distortion" and "Low Noise", for improving harmonic suppression or the S/N ratio require that an attenuator is fitted.

"Normal"

The generator provides an RF output signal with high signal to noise ratio as well as low distortion, according to the data sheet.

"LOW Noise"

This setting forces the generator to optimize the signal to noise ratio.

"LOW Distortion"

The generator reduces distortion (harmonics) of the RF signal.

Remote command: 
 
Amplitude

Sets the RF level of the RF output connector.

The level entered and displayed here corresponds to the level at the RF output, that means any offset entry is not considered.

Note: Suppressed values in the status bar

If the instrument displays asterisks instead of the values, the display has been disabled for security reasons, see "Annotation Frequency" and "Annotation Amplitude".

Remote command: 

[:SOURce<hw>]:POWer:POWer

Note: The SCPI command [:SOURce<hw>]:POWer[:LEVel][:IMMediate][:AMPLitude] sets the level of the "Level" display, that is the level containing offset.

 
Limit - RF Level

Sets an upper limit for the RF output power.

You can use it to protect your DUT from damage due to high input power. If you enter an RF level above this value, the instrument limits the output power to this specified value, and generates a warning message.

However, the level indication in the status bar is not affected.

Note: The value is not affected by an instrument preset (PRESET key), *RST and the "Save/Recall" function. It is influenced only by the "Factory Preset" and the factory value is equal to maximum level.

Remote command: 
 
Offset (Level)

Sets the level offset relative to the RF level.

The level offset of a downstream instrument (for example an attenuator or amplifier) is entered.

The entry does not change the value of the RF level at the RF output. It only changes the RF level displayed in the display header. The value of the RF level in the header corresponds to the level at the output of the downstream instrument.

Remote command:
