Re: HP 53310A - Why did I not know about this sooner?

 

Thanks to everyone that has replied - addressing things brought up and some that haven't been..
For counting, my go-to combination is a 5335A with a 5340A (LED, but have the obligatory Nixie for eye-candy) for the high end.? While I love the accuracy the 53310a brings to frequency, rise time and jitter, it's that those are only a few of the things you can use it to determine and also how many options it allows you to approach any given criteria.? The more you use it, the more things you think of to use it for.? Many may not necessarily be the best way to solve a particular problem, but just the fact you are taking a different approach can open up new ways of thinking and solutions... it tends to make me say "Huh... How about that?" a lot.

Tam: you are right, but at least the repairs to the PSU and such is pretty easily done.? Also, there are several products HP came out with around then that share the same case... and power supply.? From what I've read, there are several revisions of the PSU and not all are as prone to failure as some.? That is from a couple references and I sure wish I remembered which ones; only preemptively replace the caps on the troublesome versions?

Re options, my daily driver has all of them and I just bought the SRAM to bring my other three up to the deep memory (I scored a deal on a batch of four locally.)? Of those only one has PS issues and, while the replacement caps have been bought, I just haven't had time to get into it - I work for a Gov contractor and evidently schedules haven't heard much about pandemics yet ;-)

On the plus side, I just walked in back and saw a pallet of 12 3458A's and 4 Fluke 5522A's... pure nerd porn.

Hi,

Information about this is pretty scarce online. If anyone has a manual
to sell for HP 1208A XY display, pref including schematics, please
contact me!
A list member kindly pointed me to the Keysight PDF, but the quality
(like most of those?) is very low, although probably usable.

If anyone happens to stumble on a paper one, still interested!

Peter,

?

Which board are we talking about ?

Still looking for the LED PSU indicators on the A2 card.

?

Presume you are referring RF board..?

Is this an off the shelf part or HP proprietary?

?

Thanks,

?

Stu.

Hello Group a TAM is not needed in this case. It is simply a MMIC in the 300/600Mhz chain that is bad.

I believe Harke has a Hp85629A TAM for sale.

I suspect you might be able to rent the TAM from one of the ETE rental outfits for a month or so for not a horrible price.? I believe that Tam Hanna has one or two for sale, I may purchase one from him for my own use with my 8562A.

Hello,

either dead PSU or a cap on the display board usually lays these flat.

Hal,

Congrats on joining the modulation domain!

As you know already, it¡¯s really a sleeper. Although it works very well for viewing any sort of frequency modulated waveform, my personal favorite use for it is as an extremely precise counter. There is a reason that it¡¯s called a frequency microscope.?

FYI, adding the deep memory option is quite easy. If you search around you¡¯ll find instructions. All you need are 4 more SRAMs and to move a couple of jumpers after installing them.

Re: HP 53310A - Why did I not know about this sooner?

 

Just saw this topic. My go-to for precise time/period measurement has been the venerable 5370A. Aside from the obvious improvements such as a graphical display, history, etc., from a pure accuracy/resolution perspective, which would you pick for precision measurement? I suppose this isn't a particularly fair question, given all the additional features of the 53310A, but my typical use has been measuring such things as phase diff over time between various high-precision oscillators (example, my cesium-beam osc and a GPS-disciplined osc). I have an opportunity to pick up a 53310A, wondering if I should.

Try looking to? BAE? SYSTEMS and their surplus.? They purchased boat loads of the 3488's
Good luck.

Hi again George,

Actually finding the cards in UK has not been that easy, I did find a couple but most of what I bought came from a guy in the US.

So, i¡¯m Happy to wait until you are back in Minnesota and we can see what can be done then.
Keep safe and well.

Nigel,
There are a ton of the relay cards out there in the world.? We sold alot of the 3488A units(10s of thousands during its life).? It was a very popular system for manufacturing test.? I would think you could find the relay cards in the UK for alot less than I could send any for cost of shipping alone.? If not, I will work with you on it.? I will have to wait until I am back in Minnesota to price out shipping.

The biggest problem you will have in purchasing any I/O card except the VHF cards(44472A, 77,78,91,92)? is having the connector block still attached.? You could solder wires direct to the card if needed but that ruins the fingers.? Not a problem if you do not plan on changing connections or just have pigtails for future connections.? For Hi-impedance integrity, elliminating the connector block is desirable so it is not that bad not to have the connector block.

That certainly would be useful.

But, that web page is a mess. I cannot find a download link...is there any less dodgy looking site to find the standard? I tried searching around without much luck.
