Matt, What do you see if you display the A, B, and R with MEAS/INPUT_PORTS? ?? (I assume menus are similar the the 8753D) On my 8753D, the R channel is at about 0dB displayed (with some ripple) and

Hi Ed, WB2UAQ --- Thank you both for quick and helpful replies! Ed - with your suggestion, I remembered that I do have a 11707A and it is now in the unit (I've never used it before as I've not had

Hi, I did some tests on my working 8753ES. These results could be used for comparison. Yves

Instead of START / STOP, try entering as CENTER and SPAN. ?Just to see if it freezes when it has enough info to start a sweep, or if it is related specifically to the sweep defined by entering the

Awesome, thank you, Peter. I wonder if anyone has a fresh recollection of what battery or maybe battery-backed RAM would be suspect and possibly needed so I'd start working on an order to have the

Seems like you are on the right track.? Many HP scopes of that era lose their minds if the memory battery goes dead. Peter

And the likely price difference is worth paying in strides. I've said this before - in full agreement with Dave McGuire - but there's no price that's too high to get good, well working tools. The best

I think once one gets to use both kinds of units - "pistol" type like the FR301, and "pen" type like an SX-80/90/100 by Pace, for instance - the advantages become very clear. I've converted friends to

Bought one a few years ago and wish I had bought it sooner. It is really a fun tool to use, and having enough heat will not be a problem. I usually keep mine on the "2.5" setting or so, which

If you can locate an HP 11707A test plug in, it can be a bog help. It brings many of the signals out to the front of the unit for easy access. Unfortunately I do not see any on EBAY...

The Hakko FR301 is the only desoldering gun I have direct experience with.? I bought one after years of just using wick, iron, and heat gun or all 3.? I was thoroughly impressed with how well it

Sergey, I appreciate your input. Yes there is a trailing power cord but in comparison to some other desoldering handpieces that have both a power cord and a vacuum line having only one item helps

Hi all, Over the weekend I've got a couple of 54512Bs at my desk to seek to bring back to full functionality. My main scope is a 54522A, and I assume they have some commonalities, but I've yet to open

Mine doesn't jump at all when triggered. -Dave -- Dave McGuire, AK4HZ New Kensington, PA

There's a trick if you can do it, for holes connected to ground planes (also works for those not). You need two irons, one with a very fine tip, and one that is a conventional vacuum desolderer. put

That's a side effect of one of its biggest strengths: minimal vacuum hose length. The vacuum path from the tip to the pump is only a few inches, as compared to several feet for desoldering systems

Same success as Dave previously mentioned. I exclusively use the FR301 on every job for unsoldering components, etc. It successfully removes all solder from thru holes allowing leaded parts to be

I've had an FR301 for a few years, and I love it. It makes short work of desoldering most anything. However, six layers will present a challenge for most any desoldering tool, as you'll have to

Bruce, The FR301 is capable of delivering plenty of heat, no question about that. What I never liked about it, and the reason I sold mine, is it provides the finesse to handling or a... hammer. Which
