 Instruments User’s Manual

Section 2: Remote Operation

5. Enable source autorange.
6. Set source level to 5V.
7. Set current compliance to 100mA.
8. Set current measurement range to 100mA.
9. Set integration time to 1PLC.

10. Turn on SMU A output.

11. 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.

12. Turn off SMU A output.

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 

Figure 2-9 on page 2-14

.

NOTE Addr% is the GPIB address of the instrument and is assigned the 

value of 26.

Call send(Addr%, "localnode.prompts = 0", intStatus)

Call send(Addr%, "reset()", intStatus)

Call send(Addr%, "display.screen = display.SMUA", intStatus)

Call send(Addr%, "display.smua.measure.func = display.MEASURE_DCAMPS", 

intStatus)

Call send(Addr%, "smua.source.func = smua.OUTPUT_DCVOLTS", intStatus)

Call send(Addr%, "smua.source.autorangev = smua.AUTORANGE_ON", intStatus)

Call send(Addr%, "smua.source.levelv = 5", intStatus)

Call send(Addr%, "smua.source.limiti = 0.1", intStatus)

Call send(Addr%, "smua.measure.rangei = 0.1", intStatus)

Call send(Addr%, "smua.measure.nplc = 1", intStatus)

Call send(Addr%, "smua.source.output = smua.OUTPUT_ON", intStatus)

Call send(Addr%, "print(smua.measure.i())", intStatus)

Call send(Addr%, "smua.source.output = smua.OUTPUT_OFF", intStatus)

Call enter(strBuffer, 256, intNbytes, Addr%, intStatus)

txtData.Text = strBuffer

Using VISA

Clicking on the “Run with VISA” button will send the same commands to the Series 2600 using 
National Instruments

®

 (NI) VISA. The VISA resource is for an instrument at address 26 connected 

to GPIB interface #1. Once again, a Keithley Instruments GPIB card was used for this example. 
However, VISA allows the same code to be used with GPIB cards made by other manufacturers, 
or with altogether different interfaces such as the RS-232 or the Ethernet.
