Test Equipment Anonymous

There is a new rally at Bury St Edmunds at the end of the month. Anyone planning to go?
Buying?
Sellng?

Latest and likely final Wavetek 278 update, I have eliminated the spurious output protection alarm, this was down to the analogue board (referred to as the function generator in the manual) having bad joints on every pin of its Molex power connector *and* having many variable resistors in very much...

Got some new TE, or is it a weapon? RS-HE200-sml.jpg Sort of the EM version of a Thomson/Center Arms Contender. Four "barrels" covering 10kHz to 3 GHz. I now have full set of accessories for my R&S FSH3. It even has the antenna factors for the HE200 pre-programmed in the firmware. I't ...

I did say the Wavetek was working when last used some time ago and that it had a habit of giving an output error message that I never got to go wrong on the bench. Now you've fixed it I'd be happy to give you your £20 back :P Robert. Ah! No need for a refund, it's a thoroughly enjoyable little gene...

Telford is a bit far for me at 125 miles.
I've also just committed the entire TEA fund (teapot?) to a Best Offer on a bit of R&S kit so with luck won't have any funds....

Greetings everyone, I'm a long time reader of this thread in its original place and have decided to type some words here. Southern UK people will likely know me from radio rallies where I've a tendency to buy the odd piece of equipment, with yesterday's rally yielding a "not working" HP 1...

Went to the Milton Keynes radio rally (Hamfest) today. It was (almost) a waste of time. There were not a lot of sellers and virtually no TE. The only just about TE Igot was a handful of Greenpar inter-series coaxial adaptors. The only other thihgs tha made it not a total failure were a couple of odd...

Never imagined you were the mo and glasses type.

No, That's Rod.
I'm just behind ans to one side. No not the blonde, the baldy.

Well, yes; we all know how I feel aboot pants. I think putting them on voluntarily is a pretty big breakthrough for a tinkerdwagon... :stuck_out_tongue_closed_eyes: mnem https://teanonymous.com/f1/download/file.php?id=1505&mode=view Perhaps you'll find this interesting: https://www.guinnessworl...

No difference in the way phosphors are activated in CFLs compared to traditional fluoresent tubes. There may be differences in phosphor and even gas mix but that is true for both lamp types.
All fluorescents banned in EU and UK from next year....

Ooh don't like the stripboard. It can easilly arc across and breakdown. The SRPB bord is't the best insulator either.
A bit of bare GRP board materal and connections with just the resistor leads is better. A acrylic tube with them all in series is even better.

Judging from the single multi-pin connector on the back it's missing a separate power supply unit.

The answer to this type of scan is that you never give a one time code to somone else by phone or email etc and never use one that wasn't generated by you doing something yourself without any direction form anyone else.

My latest meter arrived today. It is a sound level meter. A CEL 393. This is a early microprocessor controlled class 1 (high accuracy) meter. CEL393.jpg On ebay from a seller who obviously knew nothing about it. There are two versions of the meter that are visually identical not even a different par...

On the original battery replacement I just took my 20+ year old Breitling Aerospace watch in for battery replacement. It has to go back to Breitling. Got a call Wednesday saying the jewler had been contacted by Breitling saying that the movment was obsolete so they would have to replace it at a cost...

Pat beat me to the Bristol description. I'd gone to bed...
Used on avionics and some jukeboxes and to keep on topic, Collins TE.

Don't get me started on tools for fastner heads. Male Hex: Metric (AF, BA) and Imperial (AF, BSW,BSF). Female Hex: Metric and Imperial. Other female: Pozidrive, Phillips, JIS, R+P, Spline (5 and 6 point), Torx, RIBE, Bristol. Plus security variations And because I do aircraft stuff you can add: tri-...

I paid £75 for my E8510A which while not Jammy Git is a pretty good buy.
I'll not be accessing it remotely. It will be nce to access the DMM and 'scope from any PC on my internal network though.

More TE incoming. I just bought a Agilent E8510A LAN GPIB gateway. So in theory I should be able to access my instruments anywhere.

25 CPS said "The 0.75A fuse in the top left of the cluster of the four did not look healthy at all and measured open. I don't know why the end caps turned colour but the fuse holder didn't. I had purchased a full set of fuses a while ago for this machine at Sayal but they only had minifuses so ...

Yes properly organised car meets with the site owners permission are common and not a issue. The problem is when lots of barely legal (at best) vehicles turn up un-announced and start making noise and smoke (burn-outs). This is fundamentally illegal. These people don't care about others. Note they g...

I've had another look at the Advance OFS-2B frequency referene. Thanks to Frequency I have a manual. It's clear the unit is not operting correctly even when fed a generated 200kHz signal. The AGC deos not seem to be working proprly. Unfortunatly the circuits in the manual do not match the unit I hav...

The transformer is the little toroid with 3 windings. Operation is odd. One winding seems to go to an oscillator on the mains side, one drives the main switch MOSFET gate and the third is feedbck from the DC side. I think the feedback saturates the core cutting the drive. I was able to dig out the f...

I picked up a bit of TE on Thursday. A HP 8920A communication test set. It was a Buy It Now on ebay. Only acouple of pictures of the front. "for spares or not working" with a note that the power supply was blown. Price was only £75. Collection only. No time to ask questions, I hit buy. I t...
