So I used to not care about being able to control my equipment with a computer. But recently, I have changed my mind - using Matlab (but I guess the same can be done with python?) I can control my test equipment, and this to me is becoming an important feature when shopping for new equipment. There are two main reasons why I want this:
The first is to extend the capabilities of the instruments I have with software for example, I made a 'better' continuity meter using my keithley 2000: it will display the resistance, not have an annoying sharp buzzer, I can change the threshold on the fly (because the meter is just measuring ohms and the 'threshold" is figured out on computer), it logs the last values, etc...
The second is doing measurements that are a pain by hand because it involves changing multiple instruments constantly. Using my arb as a signal generator I can measure low-frequency filter response by having it sweep across the frequency spans and reading the voltage from the multimeter. (of course, no phase, but I guess I could use a scope to do so if I really wanted).
My next step is to buy a few GPIB adapters so I could connect some of the older instruments to my computer as well.
So, does the ability to control test equipment with your computer matter when you are looking for a new tool?
