Was thinking of cutting the double banana plug off, and replacing it with Bnc (with the shunt capacitor also). Was also thinking of putting BNC on the amp for both probe and another for the output.

Thanks for the helpful suggestions, I will check the voltage potential on my DVM. Regards Richard Murray

jm I checked the manual on my protek 506 dvm & it said that the test current for diode testing is 1 ma. The diode in question is acting as a switch which is controlled by a bias voltage based on

Gleamfollower Any suggestions on how to test a schotsky diode. Thanks Richard

I do not think that it is current that would kill schottky diode, it is reverse voltage that might do it in. Some of very old meters were putting 100 mA on low ohm range, but I do not think that there

We have a good cross section of HP parts for test gear, plus an extensive on line cross reference for HP semiconductors, and a look up table for many CRTs. you can see this info here:

Couple of ways: 1) See how well it acts as a mixer in the frequency range in question. (This is what I usually test, since the DUT is usually part of a mixer assembly.) 2) Use a curve tracer with

Hi all, I've got an HP 3469B multimeter that's not behaving as it should - the display is behaving sensibly, but the values bear little relationship to the electrical signals applied. Nothing looks

I have a good-condition HP 3580A spectrum analyzer with many broken knobs. All four of the span/resolution/sweep knobs to the right of the CRT are busted, as well as the input attenuator knob. Since

Good idea for a group, possibly even overdue! Sometimes useful service manuals are available here. http://www.rfsup.com/servicem.html Richard

Dave, Sometimes when I fire up all my equipment, I wish I had a pair of those hearing protectors that construction workers use. The whiniest (if such a word) of my equipment is definitely the HP

George You definitely know the fan is on ..... It is definitely noiser than a tek 7904 , 496 or a 2200 series... not what I would call objectional per se but far from silent. I think HP in general

Hello Dave, How about this for a coincidence: I just purchased the 54111D manual on CD from you at eBay. I figured I'd look the manuals over before I made a decision. Thanks for your input. I was

Other things to consider in owning either of theses scopes I have a love-hate relationship with my (2) 54111D's On the love side... 1)They are very easy to use, the menus are well thought out and

Hi, First off this is an excellant idea for a group and I wish it much success, but I guess that really depends on us and how we use it! I have acquired a HP 226A generator and am looking for a

Hello everyone, I am thinking of buying a scope from eBay, and I was looking at the 54111D and the 54112D. Does anyone here know the difference between them? Cheers, George Hrysanthopoulos,

I'm having a problem with the sampler board. I have service manual but the when I inject a signal in J1 on the board it disappers after the schotky diode which checks ok on my DVM. Anyone have any
