Series 3700A System Switch/Multimeter User's Manual
Section 4: Applications
Example: Using the scanning and triggering model
This example demonstrates how to use the scanning and triggering model of the Series 3700A to
maximize the speed of the test by preconfiguring the sequence of crosspoints used.
This example uses a TSP script to configure the instruments for testing. Once the instruments are
configured, the Series 3700A internally manages all close and open actions, as well as any triggering
signals, to interface with the System SourceMeter instrument. No separate script is required to
sequence these actions.
As with the previous examples, a full I-V sweep is performed on each of the six diodes. Data from
these tests is available from the System SourceMeter instrument after all tests have been completed.
Set up communication
In this example, in addition to the TSP-Link interface serving as a communication bus, it will also
serve as triggering bus to enable hardware handshaking between the System SourceMeter
instrument and Series 3700A.
The communication setup is identical to the setup in the previous example; see
(on page 4-10).
There are three digital lines in the TSP-Link cable that may be used for triggering. This example uses
trigger lines 1 and 2. The Series 3700A outputs a trigger signal on TSP-Link line 1 and waits for a
trigger signal on TSP-Link line 2 before proceeding with the next set of crosspoint closures. The
System SourceMeter instrument outputs a trigger signal on TSP-Link line 2 after completing its test
and waits for a trigger signal on TSP-Link line #1 before testing. The triggering setup is illustrated in
the figure named "TSP-Link interface" in "TSP-Link and interactive triggers."
