Any one can provide a sample source code for K2651 and K3706

Any one can provide a sample source code for K2651 and K3706 synchronization measure?

K2651 and K3706 connect with TSP.

Now we use following code to test. K2651A is configured as node[1], K3706 is node[2]


SMU = node[1].smua
DMM = node[2].dmm
SMU.source.func = SMU.OUTPUT_DCVOLTS
DMM.func = 'dcvolts'


for i = startv, stopv+step, step do
SMU.source.levelv = i
DMM.measure(reading_buffer)
SMU.measure.i(smua.nvbuffer1)
end


These codes work fine, but the measurement is not 100% synchronization measure, I want to measure using trigger mode, any one can provide me a sample source code for modification. Thank you very much.

Thanks for viewing.

This will require understanding of the Trigger Model which can be found in 2651A and 3706 manuals.
You can download the 2651A and 3706 manuals from this link:

Attached is a script which configures a 3700 and 2600 to perform a Source-Measure
Scan sequence in three different ways. In the first method, every operation
of the scan is performed entirely in script to demonstrate the speed benefits
offered by using TSP-Link and TSP scripts versus using straight one command
at a time GPIB communication. In the second method, the trigger models of
the instruments are used to eliminate the overhead of command processing and
perform the scan sequence at the maximum speed possible. In the third
method, a second SMU channel is brought to perform the test simultaneously,
effectively doubling the scan rate of the test system. Thanks to the advanced
trigger models of the Series 2600 Source Meters and Series 3700 Switches,
as well as TSP-Link and advanced TSP-Link triggering, scan rates well over
1,000 channels per second can be achieved with relative ease.

This example should be able to help you understand about Trigger models and
develop your required scripts.

Hi, SiongKeatC

Thank you very much.

I want to measure voltage directly from the analogue backplane connector of 3706 and synchronous with 2651A. 2651A is being used for measuring high current with source voltage to a photovoltage cell and 3706 is for monitoring small voltage on a reference cell. So 3706 is used as a DMM only.

I just want to use the trigger mechinism in 3706. But I know the trigger in 3706 is for scan only.

I want to know how to change the source code you provided to fit my purpose that use DMM function only not use scan .

Best regards.

Sorry, I only use 15-pin Rear Panel of KE3706.

coolzerg, care to advice how did you do that? I am facing the same problem as well.

Thank you in advance
