content: Today from Ebay . . .With user manual, remote controll manual and 4 roll of paper for the printer.Not exactly the right thing for some electronic-smd-guys. Maybe someone is interested. I have fun to play around with itRound about from 1988. Fully functional and precise. And from W&G you can expect a high build quality. Only the printer jammed. Has two outputs (Volts & Amps) on the rear for an oscilloscope.Direct current measurements up to 30A, voltage up to 500V. Comes with a 1000/1 A current clamp. Measures up to the 50th harmonic.1st picture: DUT is a vacuum cleaner at full power. ~6.05A at 225V2nd picture: Harmonics in % of the fundamental (50 Hz). Cursor is at 50 Hz.3rd picture: DUT at ~40% power4th picture: Overview of effective, reactive and apparent powerThat was only a quick play around. Have to read the friendly manual

content: Quote from: Vgkid on April 20, 2014, 09:52:37 pmThanks, Vgkid.Maybe i will do a teardown. There are some interesting parts in it. I already have ~80 pics on my harddrive from a W&G SF-60 SDH/PDH jitter analyzer. But i think 80 pics are too much for the forum. I was looking for webspace and some sort of wordpress thing to show that stuff. Someday in the near futureHowever, the printer now works. The shaft of the stepper drive was totally blocked with some sort of resin. A few spatter of electronics cleaner, tiny drops of oil and it works fine.

Quality design and construction, and when there's a problem, you have a good chance to fix it. Vs. the throwaway stuff today. It's just fun to get an opportunity to work with it.

content: Quote from: Mashpriborintorg on February 11, 2015, 06:43:36 pmHi!I've seen the unit too on ebay. But with shipping to germany it is a little bit expensive. And the only reason i would buy another unit, is that I need the LCD protection glass. Mine is broken.Here are some pictures of the inside . . . .

content: Hello,I have one. Not very much useful but build quality is awesome. Weights a ton. Amazingly "silent" when you see the 4 fans inside, but these are Papst ones !Two Ni-Cd backup batteries on an internal card are to be checked for leakage (can be seen on a photo). I have removed them.Mine has some random black lines on the display (not always at the same place).I did not find any documents about this beast, except some datasheets.Rgds,Michel.

content: Hm. I just noticed than the one available on ebay, has the front fiber-optics connectors unpopulated, but seems to have more coax connectors than yours, under the LCD screen. So it must have some different options, and it will probably be missing the two fancy gold plated fiber optics end modules I see on your photos....

content: Quote from: Hugoneus on February 12, 2015, 03:29:02 amI bought my unit maybe 1,5 years ago. The unit itself costs me 50€ + 15€ shipping. The one actually on Ebay which Mashpriborintorg bought costs 34€ + 45€ shipping I think. And as i said, the only thing I need is the LCD cover glass. It's quite hard to get one piece of shielded glas in an individual size.

content: Well the seller was incredibly fast, the SF60 is here alreadyAs expected: The board with fiber optics stuff is not populated, I have an empty slot with unconnected cables ziptied all around.Goods news: the LCD is finally working, the boot hangs onto a "RAM/ low battery / data loss failure"I hope there's a back-up battery somewhere that needs to be replaced to fix the problem !My version is BN 3017/01, no options. Serial number on the front panel is U0009.

At the moment it's a bit difficult, could take a while.Quote from: ming on August 22, 2015, 10:09:36 pmThanks, but no thanks! It takes quite some time to scan this. But that is one of the great benefits from a community like this. I've learned a lot here and got so much help. And I try to give that back where I can.
