Here is very small and simple program to use Agilent E3633A as step voltage source. I used LabView to get the same functionality before. But it took almost a week to complete it. With serial command it only took me only 2 hours. I didn't know it can be that easy. Here I started with 8V and 0.5mA. The voltage is then step down at 0.004V after every 50 seconds. To run this,
- Copy the following code in a text file and save the test file with ttl extension.
- Connect the Agilent E3633A with DB-9 cable or serial cable and power it on.
- open Tera Term in serial connection.
- Click Control-> Macro and load the file you saved.
