Multi-DUT measure with Agilent LCR Meter 4284A

[Binh Tran]

Dear all,

I've just succeeded making a realtime impedance monitoring for the Agilent 4284A. the impedance data of my DUT was obtained after a definite time and the chart was created in realtime as well.

Now I want to extend my design to measure the multi-DUT in sequence (about 10 DUTs). My goal is each DUT will be measured 1 minute appart and each DUT has its own realtime chart. I dont have a solution to seperate the data from the LCR Meter and use it for each chart. Anybody can help ?

Here is my entire system

Thank you for reading.

What will you be using to switch to different UUTs? You could use that number and connect it to a case statement with the different charts inside each case.

I use 8 relay to switch between 8 DUTs 1 minute apart in sequence. The hardware is working well, I just don''t know how to store the data for each DUT (and make a chart) in my case. Could you expain more detail about a case statement. Thank you

If you don't know what a case statement is then you need to take the tutorial before doing anything else.

There is nothing in your code that could control the relays so you need to add this. You have not provided any details on how this is being done but I would imagine that you would be sending a number (i.e. 0 through 7) to select a specific one.
