Series 2600 System SourceMeters User's Manual
Using the Series 2600 as a traditional GPIB instrument
The following pseudocode describes how the Series 2600 will be configured and
controlled to source voltage and measure current for this example. Some of the
settings are default values restored by resetting the instrument, but they are
included to show a typical setup and measure sequence that might be used for
such a test.

Command sequence
The commands that implement the pseudocode are listed below. The syntax for
the "send" and "enter" commands is for a Keithley Instruments GPIB card. To use
a Keithley Instruments GPIB card in Visual Basic, you must include the
"ieeevb.bas" module in your project. This module is included on the CD that
comes with your GPIB card.
When you click the "Run with GPIB" button on the GUI, the commands are sent to
the Series 2600 and executed. The single reading returned by these commands is
displayed in the Data text box as shown in
Reset SourceMeter to default settings.
Set display to show SMU A source and limit settings.
Set display to show current measurement.
Set source function to DCV.
Enable source autorange.
Set source level to 5V.
Set current compliance to 100mA.
Set current measurement range to 100mA.
Set integration time to 1PLC.
Turn on SMU A output.
Measure the current and put reading in instrument output queue. This step
is similar to using a SCPI "READ?" query to take a single reading.
Turn off SMU A output.
