Calibration and Compensation
Calibration and Compensation Procedure without Using Dedicated Test
Fixture
Step 2. Click the OPEN button in the calibration window and measure the open calibration data.
6. How to measure short calibration data
Measure the short calibration data as follows:
Step 1. Connect the short standard to the DUT connection terminal.
Step 2. Click the SHORT button in the calibration window and measure the short calibration data.
7. How to measure load calibration data
Measure the load calibration data as follows:
Step 1. Connect the load standard to the DUT connection terminal.
Step 2. Click the LOAD button in the calibration window and measure the load calibration data.
8. How to measure DC open/short/load calibration data
When you want to use the dedicated open/short/load standard to measure DC resistance
(Rdc), follow these steps to execute additional DC open/short/load calibration.
Step 1. Connect the DC open standard to the DUT connection terminal.
Step 2. Click the DC OPEN button in the calibration window and measure the DC open calibration
data.
Step 3. Connect the short standard to the DUT connection terminal.
Step 4. Click the DC SHORT button in the calibration window and measure the DC short
calibration data.
Step 5. Connect the load standard to the DUT connection terminal.
Step 6. Click the DC LOAD button in the calibration window and measure the load calibration
data.
9. Specifying creation of automatic setting file for when power is turned ON
The setting conditions of the 4287A, including calibration data and compensation data, can
be automatically stored for reuse in a file named “autorec.sta” in the internal nonvolatile
memory. To use this function, click the
Auto Recall check box upon completion of
compensation so that the check mark (
√) appears.
NOTE When the 4287A is turned ON, it searches the internal nonvolatile memory for a file called
“autorec.sta,” and if it is found, the setting conditions (including calibration and
compensation data) stored in the file are automatically recalled.
10. How to end calibration
Press the Done button in the Calibration Dialog box to end calibration and close the dialog
box.
