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

Set the frequency to 0.0 MHz.? ? Does the RF level meter in the RF section go to zero? The phase lock loop that most often needed adjustment is the 350 to 450 MHz loop (in the swing-out assy on

First experiment - swapped 11661B module with a supposedly-OK "just in case" spare I had picked up a long time ago (with understanding that the 11661B manual has an adjustment procedure to use when

I have a job that requires removing a 56 pin PCB connector from an HP 6 (or so) layer motherboard. I'm considering the Hakkp FR301 desoldering tool - if anyone has experience using this tool for a

Well, I just picked up an Arco SS-32 Precision Standard Capacitor Set for the equivalent of about $75 all up, so that's a start. It has some missing values and a number of doubled up values too (maybe

Hi Caesar, I hope you're well. Yes, now I remember that did come from you. Thank you so much for the service you provide, you're a credit to the community! J.

Hi, To make a first comparison, here is the output of my 8753ES at 1GHz, CW mode, 0dBm output, Trigger HOLD, measured on a Spectrum. If you have a similar image, the PLL A11 would be correct.

Sounds about right. 60 kHz is right in the range of a switching regulator of that era. I didn’t find a signal source analyzer around the particular lab I frequent, but I’d be very surprised if

Hi everyone, I am looking for some help on the repair of my 8753 VNA. I took some time trying to find the problem it myself with the service manual without success. The unit was working great and

Both your 4276a and 4263b can measure ESR. So you may take the Henry Parsons Hall way, which he did at general radio with the digibridges: First he calibrates the measurement-frequency

Turning the backlight off makes the spurious term go away when probing :) There is a soft menu button that turns off the backlight and pressing this makes the spurious vanish on the probe (that feeds

Hi Jim, thanks. I've just spent some time fishing around the outside of the chassis with a loop probe and the 60 kHz spurious is from the front of the instrument around the display. It isn't a single
