Share Your Next Must-Have Test Equipment!- What Will It Be?

Sariel:
Hello everyone,

I'm curious to know, what's the next piece of test equipment you have your eyes on?
What's the one thing you currently feel is lacking in your lab setup?
And here's a fun twist: if you were handed a $5,000 voucher to splurge on one item, what would you choose?

Personally, I've got my sights set on a comprehensive Vector Network Analyzer (VNA) with full port capabilities (S21, S11, S12, S22), and I'm leaning towards the Siglent SNA, covering up to 4.5GHz.

What about you?


RoGeorge:
Depends on what you already have, and on what area of electronics you are interested in.  Is it for learning/hobby, or for work?

A good VNA is priceless, though unless you need to make metrology  grade measurements, a $100 nano VNA might be enough.

As a caprice for myself, a SMU would be also tempting to have, or maybe a Lock-In Amplifier.

Hello,

could the Lock-In Amplifier Operation be useful in Analog Discovery, perhaps in the context of a preamp?

Best regards

With a $5k voucher, I would get an SDS3000X HD when it comes out here.

If it was a ~$20k voucher, I'd be torn between the SDS7000A, or an Instek LCR-8350.

A LIA is particularly useful when a very small signal has to be recovered from all kind of large noises and other signals.  However, it can do that only when another clean signal is available, and synchronous to the small one that has to be recovered.

Depending on the LIA model, might be possible as well to use it as a generic filter, or as a low frequency PLL, or even as a generic preamplifier.
