Step 3: Obtain and Install Coaxial Shunt Resistor De-Embedding File

Step 3: Obtain and Install Coaxial Shunt Resistor De-Embedding File

For maximum DPT accuracy, the Coaxial Shunt Resistor's De-embedding File
(also known as a Transfer File) must be installed in the oscilloscope.
Recharacterization of the Coaxial Shunt should be performed annually and the
updated De-embedding file installed in the oscilloscope. The Coaxial Shunt
Resistor's De-Embedding file has to do with maximizing the Shunt Resistor's
bandwidth and requires configuration on the oscilloscope.

Annual Characterization of the Coaxial Shunt

The Keysight PD1000-61901 Coaxial Shunt requires annual characterization;
return the Shunt to a Keysight Sales and Service Office for characterization. A list
of offices is available at:
After the shunt is characterized, Keysight will return the shunt to you. This
provides the latest characterization .tf2 file. Download the file from the Keysight
Infoline website and install it in the oscilloscope.

Obtain the Shunt De-embedding file

Whether the initial installation or installation of the de-embedding file after
characterizing the shunt, the process is the same:
1 Locate the Coaxial Shut Resistor Serial Number located on the side of the
2 Go to Keysight Support Portal:
3 Enter the shunt's product (model) number (PD1000-61901 or PD1000-61902)
4 Select Calibration Documents tab.
5 Select the Certificate Number (for example, PD1000-61901MY58400001
6 Click the appropriate service document file, for example:
1 PD1000-61901 or PD1000-61902 are the Keysight part numbers for the shunt. If you need to order additional shunts, order Keysight
part number PD1500-61901AU-SH1 or PD1500-61901AU-SH2. This includes a characterized shunt, mounting bushing, serial number, and
installation instructions.
