About the Series 2400 examples 

This section provides examples that demonstrate the basic interaction of the Model 707B or 708B 
with a Model 2400 SourceMeter Instrument. One of the examples also shows how to use digital I/O 
triggering to synchronize source and measure actions between the Model 707B or 708B and the 
SourceMeter instrument. 

The concepts in these examples can be applied when using the Model 707B or 708B with other 
SCPI-based instruments. TSB Embedded cannot be used to program the Model 2400 SourceMeter 
Instrument; it cannot be used for these examples. 

 

Equipment required to run the examples 

To run this test, you will need the following equipment:  

 

Six diodes with triaxial connections 

 

One Model 707B or 708B 

 

One switch matrix card (Model 7174A, 7072, or 7072-HV). You can also use the Model 7173-50 if you 
convert the connection to coaxial instead of triaxial 

 

One Model 2400 SourceMeter instrument or equivalent source measurement unit (SMU) 

 

Example 2 only: One Model 2600-TLINK trigger link to digital I/O cable assembly 

 

Two Model 237-BAN-3A banana jack to triaxial cable assemblies 

 

Connect the equipment 

To run the test, make the connections as shown in the figure below. Note that all triax connections for 
the SourceMeter Instrument and the diodes are made to the center conductor (pin) of the triaxial 
connector.
