Re: Cleaning Sealed Or Inaccessible Potentiometers

Pedant alert!
As you got the deoxit into them the pots are clearly not "completely sealed". Fully enclosed with no access maybe.

Re: Fluke Friday - Going through the Fluke Collection

There are scopemeters and there are scopemeters.The original Phillips models are OK (screens are poor by modern standards). So are the Fluke 199C onwards. I presume you are refering to the 123 scopemeters which would be beter named Meterscopes.

Re: Fluke Friday - Going through the Fluke Collection

I paid list for my pre-release 87 when I worked for Philips Lighting. Over the course of 6 paychecks, yes, but I still paid it because after using it for a month as my issued meter, I wanted to keep it that much. It was my daily driver and first at hand; whatever the gig, when it was set up on my b...

Re: Ebay Standards of seller.

At least that is just a matter of judgement. I see many items of TE listed as tesed and working dispite having obvious serious defects in the photos, missing critical separate parts or accessories (often matched to a specific instrument). There are also the items listed as tested when it is clear fr...

Re: tinysa ultra vs hp8569b

Very interesting comparision.
The tinysa is better than nothing and very handy but clearly poor performance compared to a very old real spectrum analyser. Very poor local oscillator performance is evident from distortion of levels close in to signal.

The "Nano VNA" things are interesting but are pretty limited particuarly the cheaper ones. When they say to use a 10dB attenuator on each port to isolate the mismatch (the ports are not 50R) it makes me worry. Their dynamic range is low enough without knocking 20dB off before you start. If...
