Used test equipment websites? - RF Cafe Forums

The original RF Cafe Forums were shut down in late 2012 due to maintenance issues - primarily having to spend time purging garbage posts from the board. At some point I might start the RF Cafe Forums again if the phpBB software gets better at filtering spam.

Below are the old forum threads, including responses to the original posts.

I'm looking to set up a simple electronics test station for working on old AM and FM radios. Thinking about maybe doing some restoration in my soon-to-be retirement. Any suggestions for where to pick up reliable used TE (other than eBay or Craig's list)? I've found some Ham sites but am leery about dealing with unknowns. How about new TE (signal generator, bench supply, spectrum analyzer, etc) at a decent price? I've done a lot of searching and know there's a lot out there for the taking, but I'm looking for some direction from someon who has done this already. No sense reinventing the wheel. BTW, I did mostly digital electronics so the RF world is kinda new. Any suggestions for books would be appreciated too. I've made enough bad purchases in my days (about 62 x 365 of them) that any sage advice would be appreciated. :smt020

I have bought a lot of test equipment off of ebay and never had a problem. You have a chance to ask questions before making a bid. Also ebay will settle disputes if someone tries to rip you off. I think most credit card companies also protect you against fraud. Your most risky option is to deal personally with cash. Go for it!

5 years ago you could have great luck finding bargains on ebay. Now about half of the stuff for sale is junk/non working.

You need to stay with sellers that have a rating of better than 300 reviews and no less thatn 99.5% positive ones! You also need to check to see if the guy routinely sells equipment! You do not want to buy a $3000 spectrum analyzer from a guy that has a great reputation selling womens handbags! That is almost certainly a sign of a scam!

AM/FM stuff....there are good deals on ebay for E4401B spectrum analyzers that will work up to 1.5 Ghz. Make sure the options are right (50 ohms, etc). If that does not work, you can go cheaper with an 8566b. In that case, make sure the screen is bright and sharp.

Jimmy I recently started buying some new test gear at great prices to setup a nice electronics test lab at home. Not only was I able to find great prices on new equipment, it has great capability and remote interface, so I can automate the measurements. B&K Precision, Rigol, GW Instek, Hameg and a few others (see elexp.com Electronics Express to see some of it). I was amazed at some of the prices and capibility.
I got a B&K 2.4GHz freq counter and 4 3/4 digit DMM for just over $400 each. I got a 100MHz dual channel Oscope from Rigol for under $1000 and I am looking to get the 4000 series 60MHz function generator for about $800. They have a lot of digital equipment at good prices as well. The equipment all has remote interface so I can automate them. I saw several Spectrum Analyzers for about $4000-$5000 that go to 3GHz and have RBW's down to 1-10Hz and DANL's lower than -140dBc and again with full remote interface. I do not recommend a Spec An with RBW >30Hz minimum.
The Rigol function gen had AM/FM and PSK, Full arb waveform and over 200 waveforms available. Contact me by email and we can discuss more. Also See the B&K, RigolNA.com (Rigol North America) websites and the others for more info on latest equipment. All new with warrenties and certificates of accuracy.
