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

 

¿ªÔÆÌåÓý

Stay OFF the Danaher 57x series. My replacement for these is almost ready.

As for the 53310A: not sure if it pays. You would need to use an FPGA to harvest the digital data being farted out. I wanted to do it once, but never had the time. However, afaik, the video board on these units is a separate board (as per the late Jzon Geller), and some instructions in the service manual of the 53310A even give some data about the pinout.

That's something I've been thinking about for a while now. I have several instruments where I'd like to replace the CRT. I know there have been a few people in the past that have done some for specific instruments, but I don't know of a general solution. One would think that for many instruments, should be fairly easy. They usually used OEM CRT displays that had simple analog or pseudo-digital intensity signals, and standard or close-to-standard scan rates. But, for the older style oscopes where it was a classic deflection CRT with the text additions being done by vector graphics, whole different game.My 54540 really needs a new CRT, modern replacement would rock. I'll add it to my list. :)

For a very informative "Cliff-Notes" summary of the 53310A and some of it's capabilities, here is a link to a write-up Geller labs did:

Another thing... the CRT it it is the same one used for several HP products - does anyone know of a compatible CRT to LCD conversion kit?? Probably not, but wouldn't that just be something!

Tam - I meant to say "Thank you!" earlier - when I was trying to find out what they were and whether I should pull the trigger on the purchase opportunity that I had, it was your excellent videos that convinced me to do so.? I decision that I am very, very happy to have made.

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

 

Hal,

?

It¡¯s a slick little machine.? I managed to pick up a couple of units off of ePay, one being a real beater with needed options, spent an afternoon in surgery and pulled together a nearly new unit with full options.? The 2.5 GHz channel C option (030 minimum, 031 the best) is a must.

?

If you are into spread spectrum and other frequency hopping applications it sure makes it easy to see where things might go wrong.? And it can be helpful with the usual phase noise stuff.

?

I highly recommend obtaining the paper copy of the ¡°HP 53310A Modulation Domain Analyzer Operating Reference Manual¡± (53310-90037) to keep handy near the unit to thumb through if you get lost.? It often pops up on the auction site.

?

There are times when I find that the resolution of the instrument is not as good as it could be in certain applications but overall you will find it very useful.? Even supplanting the Option 010 (OCXO) with an external GPSDO 10 MHz signal adds an extra bit of accuracy to it.

?

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.

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,

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.

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.

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.
