Calibration commands
Command** Description
smu X .contact.calibratelo(
cp1Measured , cp1Reference ,
cp2Measured , cp2Reference )
Adjust the low/sense low contact check measurement calibration.
cp1Measured
(value measured by SMU for cal. point 1).
cp1Reference
(reference measurement for cal. point 1).
cp2Measured
(value measured by SMU for cal. point 2).
cp2Reference
(reference measurement for cal. point 2).
smu X .contact.calibratehi(
cp1Measured , cp1Reference ,
cp2Measured , cp2Reference )
Adjust the high/sense high contact check measurement
calibration.
cp1Measured
(value measured by SMU for cal. point 1).
cp1Reference
(reference measurement for cal. point 1).
cp2Measured
(value measured by SMU for cal. point 2).
cp2Reference
(reference measurement for cal. point 2)
* Calibration point 1 should be performed at approximately 0% of range; calibration point 2 should be performed at
approximately 90% of range. See
Step sequence (on page B-22) for calibration points.
**
smu X
: For Models 2601B, 2611B, and 2635B, this value is
smua
(SMU Channel A); for Models 2602B, 2604B, 2612B,
2614B, 2634B, and 2636B, this value can be
smua
(for SMU Channel A) or
smub
(for SMU Channel B).
Calibration adjustment procedure
Use the following procedure to perform remote calibration adjustment by sending commands over the
IEEE-488 bus, RS-232 port, USB interface, or LAN. The remote commands and appropriate
parameters are separately summarized for each step.
Step 1. Prepare the Series 2600B for calibration adjustment
A. Connect the Series 2600B to the controller IEEE-488 interface, RS-232 port, USB interface, or
LAN using an appropriate interface cable.
B. Turn on the Series 2600B and the test equipment, and allow them to warm up for at least two
hours before performing calibration adjustment.
C. Make sure the IEEE-488, RS-232, or LAN interface parameters are set up properly (to configure
the interface, press the
MENU
key, and then select
RS232
,
LAN
, or
GPIB,
as applicable;
configuration of the USB interface is not necessary so it is not available).
