I would caution against taking the power supply recommendation for two reasons.
(1) Don't buy equipment without LXI as IMHO once you get going you really need coherent and scriptable ethernet control of everything. Yes, you can work manually or use some oddball vendor tool over USB. Yes, it's slow, error prone, and frustrating. The difference between getting things done and getting burned out is largely down to choice of tools. Spend the money.
(2) Multi-channel is important. Pretty much anything needs more than one voltage. It really sux having multiple PSUs because it doubles bench space, cable overheads, is a pain to synchronize. I would recommend a three channel supply with LXI at a minimum.
- InvisibleUp 3y agoRegarding point 1, USB-TMC is just as good as LXI, really. Completely industry standard, just like LXI or GPIB. LXI is great if you need it, but you probably don't if everything's on the same desk. And there's even more instruments that just create a virtual COM port over USB and allow SCPI commands over that, and that's perfectly fine. You just have to configure it via something like [Keysight's Connection Expert program](https://www.keysight.com/us/en/lib/software-detail/computer-software/io-libraries-suite-downloads-2175637.html https://www.keysight.com/us/en/lib/software-detail/computer-...) first.
- contingencies 3y agoYeah, no. USB is terrible at resisting electrical interference and has a world of poor cables with a connector half-life of about 10 years. TCP/IP over STP is cheap, ubiquitous and not going away. Routable instrument control > non-routable instrument control.
