Overview

The instrument has the capability to extend the Reference Plane beyond the factory calibrated RF Output port. The Reference Plane can be extended via Corrections and/or S-parameter de-embedding.

Up to four stages of correction and de-embedding are available. These stages are referred to as blocks and are labeled as Block A, B, C, and D. For SCPI commands, block A=1, B=2, and so on.

The following table lists the available correction and de-embedding components for your test setup.

Component	Purpose	Supported File Format(s)
Factory Cal	Directly measured correction data created during the factory manufacturing process or annual calibration.	N/A
Block A	User correction data applied on top of the Factory Cal. For this block, you can: either apply corrections from a specified correction file. or measure directly with a supported power meter, spectrum analyzer, or network analyzer to generate a correction file.	.csv .uflat (for compatibility with other Keysight Technologies signal generators)
Block B	De-embedding of fixtures including cables, connectors, and other passive components between the instrument and DUT to remove the effects of these test fixtures from the measurement results. Individual fixture blocks represent different fixture elements in your test setup. Calculated correction data for the sum of Blocks B, C, and/or D is applied on top of the Block A and/or Factory Cal. Prior to the software version A.14.00, only the S21 data of the fixture was used for correction. With software version A.14.00 or later, the S11 and S21 data of the fixture are used for correction. Due to this difference in the S-parameters used for correction in these software versions, the calculated correction data may vary for these software versions.	.s2p

Add from Measurement

You can use the Block A properties > Add from Measurement button to access the Measure Corrections wizard. Using this wizard, you can configure and run the user correction measurement. The correction data generated from this measurement is saved to a .csv file. This file is then used as the correction file.

The subsections below describe the SCPI commands available to configure and run the user correction measurement.

Configure Sensor

SCPI commands defined in this section can be used to set up Correction measurements and Power Sensors used. In the user interface, these settings are included in the RF Output block's, Corrections/De-embedding block setup, when the Add from Measurement button is selected.

Measure Correction Data

The measured correction data will be saved to the specified file. The file path can be either a full or a relative path. When a relative path is given as file path, it will be based on D:\Users\Instrument\Documents\Keysight\PathWave\SignalGenerator\Corrections. If no file is specified, a file name is automatically created.

This is an overlapped command that initiates the Correction Data measurement. The measurement can be aborted by the Abort command.

Note that the reference clock must be locked between the signal generator and the spectrum analyzer.

File

Sets or queries the correction data file (.csv or .uflat) for Block A and .s2p file for Block B, C, or D.

The default folder location is:

For M9383B, M9384B, and M9484C:

<Documents>\Keysight\PathWave\SignalGenerator\Corrections

File format for Block A

For Block A (1 in SCPI), the file can be a .uflat file compatible with other Keysight Technologies signal generators, or a .csv file.

The .csv file must be formatted as follows:

The first line is a header.
Each line thereafter must contain three values separated by a comma:

The lines must be in increasing value of frequency; e.g. the lowest frequency in line 2, the highest frequency in the last line of the file.

For M9484C with N7653APPC subscription date of June 1, 2024 or later, the following two formats are supported for Block A .csv file:

the Frequency,Amplitude,Phase format described above
or the Frequency,Amplitude,Phase,Time format as described below

Frequency,Amplitude,Phase,Time format .csv file

The first line is a header.

Each line thereafter must contain four values separated by a comma:

The lines must be in increasing value of frequency; e.g. the lowest frequency in line 2, the highest frequency in the last line of the file.

Update Quiescent Temperature

For M9484C

Remote command only.

Immediate action. Refreshes the quiescent temperature used for phase compensation at the time the Channel to Channel (C2C) correction is performed.

This command allows you to update the quiescent temperature for amplitude. However, this update is not a prerequisite for performing the C2C correction. It's important to note that the update of the quiescent temperature for amplitude is carried out during the Alignment process. Also, it's mandatory to run the Alignment before performing the C2C correction.
