NOTE

Storing test results in exportable Keithley Data File (KDF) format

You can save all of the data in a KITE project into a single ASCII-formatted file in Keithley
Instruments Data File (KDF) format. KDF format is the data format used by KTE in the Keithley
Instruments Models S600/630, S400/450, and S900 testers.

Thereafter,
the header fields are null or unused, because the Model 4200-SCS is not a multi-lot, multi-wafer
system like the Models S600/630/680, S400/450, and S900.

KDF user tag data

The <TAG>"x,y",value,value is used to hold the current site's x and y position. The same
information is displayed in the Settings Sheet of the ITM or UTM in the Site Coordinates row. This
<TAG> is inserted before the data for each test. Since each test can have different site
coordinates, using <TAG> is a way to place the info in the file more than just at the beginning of the
site (site_id, row, column). The <TAG> is from the Model S600 definition and is used to hold data in
the following format:
<TAG>"x,y",value,value
•
<TAG>
•
"x,y"
•
value, value
