Jon, very useful info, but please translate this line near to the end:-- Look at current wave over a wide range of PRF and tie scae. Cheers, Les.

Alex: As SMPS/EBU/magneitcs designer and mfg ,since 1970s I Have used TEK current probes and amps , have had many. such probes and problems. 1/ Buying used ff epay is ALWAYS risky: Besides the

It's not the spring that stresses the plastic, it's the extra tension when you close the probe fully. On my P6021, the slot at the end that the slider's tab engages broke. I epoxied onto the nose a

Late last year I purchased a P6022 current probe on ebay, which was advertised as being in good working condition, although on the pictures it was evident that at the very least that probe had seen a

Thanks for the correction - I was way too abbreviated. mike

I have I think four P6021/6022 CPs should anybody want one. Fair offers only considered. All have been checked, but otherwise three are unused, one slightly used/ I have PSUs and or the basic

Mile in 1980s, I was friendly with Dr's Middlebrook, and Cuk, visited the lab in Pasadena at The UC campus Dean Venable was indeed the "Dean" of power supply stability measurement, he visited my lab

Hi John, Middlebrook wrote his seminal paper of the feedback measurements in 1975, later went on tour with Dr. Cuk for Switching Power Supply design for several years, that included updated papers on

Mike, I took Middlebrook's circuit analysis class (EE114) back in 1971-72.? I remember the wave analyzers feeding current probes as signal injectors. --John Gord

Thank you. ?I am going to use this pre-amplification along with a HP wave analyzer to measure loop gain by the method promoted by HP and especially the late DR. Middlebrook. ?These days being

Mike, The 7603 vertical output signal jack comes from the selected trigger source.? If the 7606 is set for LEFT trigger, and the LEFT plugin is, say, a 7A26 in ADD, with Trigger set to Mode, and CH2

I am looking for an updated 1A1 function, that is, an A1Ch1-A2Ch2 output.? It looks like the 7603 has a vertical output on the back panel and that may do the trick.? Can anyone verify the 7603

I have a scummy 531 mainframe for sale for 25$ CDN. I won't be shipping this thing, gotta be local. It's the old square cabinet kind, no plugin, it belonged to a heavy smoker, the CRT is good, but

Well, you also have their email, yeah?..... ............. ;)

Rebonjour I just setup my 7L5 on CAL signal to compare. The zero DC peak is rather broad. so I set the dot freq at the CAL 500KHZ and then harmonics for a narrow peak. Result is indeed a slight

I got into an email argument with a member of Tekscopes, and when he found he couldn't defend his point, he got mad and turned me in to Spamhaus as a spammer... He even bragged about what he did...
