Capacitance Compensation When Using Switching Matrix
To Create Compensation Data File
This section explains how to create the compensation data file. To perform the
capacitance compensation, enter the file name of the compensation data file to the
User Compensation Data File field of the “Extended Configuration” on page 4-46.
1. Create a text file (e.g. C:\temp\c_data.txt) that contains the information as shown
below.
• For
B2200A/B2201A:
The 15th line specifies the used switch module, B2210A or B2211A.
The 16th line specifies the DUT interface, PCIF or CABLE. PCIF indicates
that Agilent B2220A pr
obe card interface is used. CABLE indicates that the
connector plate is used.
The lines C2H to C3L should be modified for each measurement
environment. See Tab
le 3-9. Do not modify the other lines.
NOTE EasyEXPERT provides the template of the compensation data file for the
B2200A/B2201A. See Table 3-11. Select and use the template suitable for your
measurement environment.
