1. Configuration

Address

Enter the instrument address.

The drop down list of Address lists the recently used instrument address and the connection strings (GPIB, USB, LAN, etc.) configured in Keysight IO Connection Expert.

Instrument

Default: N5182B

This parameter displays the model number and serial number of the instrument if the status of Instrument Connection Button is Connected.

2. Basic

Sample Rate

Range: 1 Hz to Maximum sample rate supported by the instrument

Default: 15 MSa/s

Set the sample rate of the Envelope Signal Generator. By default, this value is set to three times of the product of the Sample Rate value and Resampling Ratio value in Waveform block and the OSR for Envelope value in Envelope Tracking block.You can set it to a larger value if you like.

Trigger Source

Choice: External | Bus

Default: Bus

Set the type of trigger source of the Envelope Signal Generator.

Delay

Range: -250 ns to 250 ns

Default: 0

Set the IQ delay of the Envelope Signal Generator.

3. Output

State

Choice: On | Off

Default: On

Set the IQ state of the MXG/EXG as Envelope Signal Generator.

Voltage Offset

Range: -1.5 v to 1.5 v

Default: 0

Set the voltage offset of the Envelope Signal Generator.

Peak Voltage

Range: 0.1 to 1.1 v

Default: 0.4

Coupling:

If the Envelope Source setting in the Envelope Tracking block is set to From Predistorted Signal or From Non-predistorted Signal, this value will be calculated and filled automatically when you run the measurement.
If the Envelope Source setting in the Envelope Tracking block is set to User Defined, you need to provide the value for this setting.

Set the peak voltage of the envelope signal generator. Refer to Voltage Mapping in Envelope Tracking Measurement for more details about peak voltage.
