I think the best one of those I had was a television I bought from a jumble sale when I was about 10 and stupid. Think it was a Bush TV22. Had a sign "works ok" on it.

"Yeah of course it works! - 20p mate".

Took it home and realised the sign should have been "contains copious amounts of fire"
And thereafter went around sniffing everything before buying.  :clap:  :-DD

15MHz AWG/Counter @ $99 up to 60MHz @ $139: https://www.amazon.com/dp/B072JW8JHZ/ref=biss_dp_sa1

Holy Bleeping BleepCrackers! If you need just the basics... Counter AND dual output DDS/AWG!!!   :clap:

Plus a 6% off coupon!!!

Is a JDS6600 and can be had for a lot less. The box is full of air  ::) eBay auction: #183044531625

Yes, it can be had very cheaply if you look around.  I got a basically unused 30 MHz FY6800 (upgraded PSU and specs) from a fellow EEVBlogger for $90.  Really a nice little unit and it does a few things my Wavetek doesn't.  Not a Cadillac among sig gens but it is fine.

Some of my most expensive tools feel like chancy plastic cases with mostly air.

That’s one reason I like the Rigol stuff. Someone actually put some chinesium into the box. Feels like you got what you paid for.

Edit: Moment of insanity here. I really prefer the old 87 to the 87V. Better interface, DC amps over AC amps default and just feels better made. Considering losing the 87V

Theres loads of kit that is both expensive and good quality but yet is full of air, look at the TTi range of kit for example of which I have 3 prime examples

Your spouse, significant other, family or friends think TEAS is a dreadful disorder? Let them know,  It could be worse...



You could have CEAS: CB equipment acquisition syndrome.

Whatever its faults, the advantage of this:



over the 8640B is portability, which I have been thinking about a lot since I started haunting equipment-filled garages, looking for interesting bits of kit to acquire.  I've assembled a small bag of gear for basic taking-apart and testing but I was stuck for a decent signal generator. Then I remembered this:



My trusty, battery-powered, good to 500MHz (more or less) CAA antenna analyzer. It puts out a 400mV sine (more or less) wave over its frequency range and fits in my bag. Not a function generator but for simple testing, good enough.

...and somewhere around here I have both (HF and VHF) of the pocket-sized Autek RF Analyzers, too. If I can find them, and they still work, I can use them instead and get the bag smaller, still.

10-4 good buddy!  :-+ $500 USD for the whole lot. That's about $8 per unit. Gives you an idea how much crap band radios are in demand.  :palm: And not sure if you can analogy that to TEA. Looks like plain old hoarding to me.....although a hoarder wouldn't sell unless they were under the threat of death.  ::)

In other news. The 4x attenuator is FINALLY on this side of the pond and in the care of USPS. It took 6 days to get from Athens airmail to JFK. They must have rented a Piper Cub to fly across the Atlantic.  :-// The last time I ordered from them it was about 3 days Athens to JFK.

I have so many projects both TEA and non-TEA related that I don't need another one.  :o ;D
I keep saying that to myself, but then you post that like-new result with the 2430, bd posts the reminder that the 453 is all discrete, and mnem re-tempts with his mostly working 454. :scared:

Please, PLEASE be tempted... while I still have money for shipping!!! I'm running out of time to faff about with boat anchors until after the move; the kids are out of school in a month, and then my productivity will be decimated.  :scared:

OK, OK, Uncle! I will make it feel welcome and at home. In fact, there are no other Tek scopes for it to compete with for attention. It will be spoiled, for sure.

I have one of the older similar units. This one only goes out to 2Mhz. And yes, a whole lot of air on the inside. They also have another issue. They are floating and not grounded. It wouldn't surprise me if these newer ones are the same. There's plenty of info out there on how to safely ground them. Mine has that modification.

With these, the pendulum swings quite far the other way, though. I have the earlier FY3224S, which was made in a similar enclosure.

Edit: It's the same as the one in med's prior post, just with a different max frequency.

It's so light that you'd be temped to add some lead plates to the inside. Otherwise, there isn't enough normal force for the rubber feet to do anything useful. ;D

Feels like Tech. :-DD But, yeah, it is what it is: an inexpensive DDS/AWG. The new 6800 ones are definitely a step or two up from the 3200, but it's not going to supplant HP, R&S, etc.

My 3224 was something like $25 because it was missing the power cable. How could I refuse two channels of 24 MHz for pocket change? ;D

Anyone else having crypto errors trying to post to the forum? Trying to share a pic of a neat acquisition and it won't let me. Some kind of SSL/TLS error with Firefox.

Feelcrud (internal floating supplies) now renamed Feelelec have their issues as do the JDS (wallwart) ones. Still good bang for the $ with a power supply tweak. On the actual waveform results the JDS cut some corners and the Feelcrud beats it out.

Both offer a good gateway drug device into something more serious.

Thanks!

I fixed the main issue right away, which is that the rod that connects the on/off push switch on the front panel to the actual mains switch in the rear of the case was very loose and causing the switch to not contact properly. Now it stays on without holding the switch in!

However, there's still some more wrong with it. No stable readings and it appears to get stuck in some sort of condition where it displays 1200.00 and flashes alternately between + and some symbol I'm not sure of. Does anyone know of any documentation for this brand? Have come up empty searching.

I haven't seen any docs for those. Old stuff is hard to find. Old stuff built for government, scientific, or other niche markets is even harder.
