Remote Communication Interfaces - Keithley 2601B Reference Manual

Series 2600B System SourceMeter® Instrument Reference Manual
The SPEED setting affects all measurement functions. After setting the speed, the display resolution
can be changed using the DIGITS key. For the Model 2602B/2604B/2612B/2614B/2634B/2636B in
single-channel display mode, pressing the SPEED key for the channel that is not being displayed will
result in a display message to change to the other channel before setting the speed.
Remote speed programming
Speed command
The following table summarizes commands to control speed. See the
page 7-1) for more information.
Speed command*
Command**
smuX.measure.nplc = nplc
* The speed setting is global and affects all measurement functions.
** smuX: 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).
Speed programming example
Use the NPLC command to set the measurement speed. The programming example below illustrates
how to set the speed to 10 PLC:
-- Set NPLC to 10.
smua.measure.nplc = 10

Remote communication interfaces

You can choose from one of several communication interfaces to send commands to and receive
responses from the Series 2600B.
The Series 2600B can be controlled from only one communication interface at a time. The first
interface on which it receives a message takes control of the instrument. It ignores the other
interfaces until the instrument is returned to local operation.
