Level Settings

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

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

For security concerns or certain operating modes you can hide the frequency and level display in the status bar.
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: 
 
Ignore Level Range Warnings

Suppresses warnings the instrument generates when either the level, or the PEP value are out of range. This function prevents automated measurements from being stopped due to a level warning.

The following warnings are suppressed in both, the history and in the error queue:
  • Level overrange / level underrange
  • PEP value greater than defined upper bound / PEP value less that defined lower bound (fix range)
Remote command:
