Specifies the amplitude of the generated signal in volts, peak-to-peak (Vpk-pk). For example, if you set this property to 1.0, the output signal ranges from -0.5 volts to 0.5 volts.

To use this property, you must use the Active Channel property to specify the name of the channel you are configuring. For the PXIe-5645, you can configure the I and Q channels by using I or Q as the channel string, or set the channel string to "" (empty string) to configure both channels. For the PXIe-5820, the only valid value for the channel string is "" (empty string).

To set this property, the NI-RFSG device must be in the Configuration state.

Note For the PXIe-5645, this property is ignored if you are using the RF ports.

Refer to the specifications document for your device for allowable output levels.

Supported Devices: PXIe-5645, PXIe-5820

Default Value: 0.5 volts

Valid Values:

PXIe-5645: 1 Vpk-pk maximum if you set the IQ Out Port Terminal Configuration property to Differential, and 0.5 Vpk-pk maximum if you set the IQ Out Port Terminal Configuration property to Single-Ended.

PXIe-5820: 3.4 Vpk-pk maximum for signal bandwidth less than 160 MHz, and 2 Vpk-pk maximum for signal bandwidth greater than 160 MHz.

Note The valid values are only applicable when you set the IQ Out Port Load Impedance property to 50 ohms and when you set the IQ Out Port Offset property to 0.
