nice DVM

Neat.

Maybe a re-branded local product from there?

I guess we'll all get used to "special English". When I come back from a trip and forget to plug in the USB cable for my scope the PC says "DSO not connect". But those instruments become quite international. Mine came with UK and German power plus (no US plug...) and the screen was set to Espanol.

Also interesting: it's not ROHS (has lead, mercury, cadmium, Cr4, PBB's, and PBDE's) and uses old-fashioned AC votage jumpering, ie it has a power transformer.

John

That really points to a re-brand. Maybe Spehro can pick up a gray market version for half during his next trip to China :-)

The DSO here is different. Taiwanese brand but all the modern things, wide voltage supply, conformity declaration and so on. I just hope it's not RoHS inside but I am afraid it might be since it was shipped from Farnell in Europe.

Sounds like the same guys who did the on-screen display of one of our TVs... if you change to, e.g., a component video input and there's nothing pumping out video yet, the messgaes is, "Main no signal." Mmm... ok!

John -- for your own instruments, at one time weren't you planning to use those switching wall-warts with the various "slide-on" plugs for internationalization? Did you ever end up doing that?

---Joel

At least it has enough similarity to English. The real tough ones are the more rare error messages in software where they didn't translate them because "it'll never show". One beam field simulator showed those in Swedish, an old layout viewer did it in French and so on. Just had one pop up in German but that's my home turf.

We have one benchtop delay generator that uses 24 volt DC input, and we furnish an external switching supply, the kind like printers use.

We are also doing a series of smaller boxes that look like

that use 12 volts, and we supply a true wart, a universal switcher that has interchangable plug adapters for different countries. Phihong, I think.

Lately we avoid running AC into a box if we can help it. Everybody seems used to external adapters thses days. Besides, they don't find out until after they've bought it!

One of our newish Tek scopes has an external supply.

I don't think you want to use a switcher PS for a sensitive voltmeter.

the old TEK 555 and 556 scopes had externals supplies,too! Big 'uns.

The dual beams? That's what the bottom shelf of the cart was for!

John

I've seen a pretty much exact copy of the 34401A, maybe the same company.

The Fluke 8845A does not cost a lot more, and has a much extended range of capability... You get what you pay for...

IIRC,the 8845a is ony 5.5 digits,and does not have the accuracy of this meter,particularly on AC volts.(more AC bandwidth,too)

Keithley is a reputable company.

The Keithley benchtops, the 2001 and 2000, are excellent. We use them, with scanner options, in test racks, interfaced to PCs. Their real-life accuracy is boggling.

Fluke got out of the precision benchtop biz for so long that we converted to Keithleys. The 8845/8846 look nice, but there's some spec that made us still prefer the K's, AC bandwidth I think.

My old Fluke 8842 was wonderful. It was only 5 digits, but had solid

100 nV resolution anyhow, much more stable than any other benchtop I've used. But it got old and flakey... I got tired of whacking it when the display dimmed.

We have one HP 34401A, which is horrible. Maybe the new 'B' is better.

John

The Taiwan-designed scope I bought goes beyond. At least for what I need it to do it works better than a similar Tektronix, for about 60% of the cost. IMHO the controls feel more solid also, like the stick shift on Japanese cars. The only weirdness besides a somewhat rocky English in the menues is the bonbon-color of the traces, and the TFT is really bright so when you turn off the lab lights it's like a night club. Somehow they managed to illuminate the channel lights in the same bonbon colors.

Didn't you buy one or more of the Atten 5501 spectrum analyzers? If so, how do they behave? I couldn't find any reviews on the web so far.

The point is to avoid the tests for power line connected equipment.

Definitely not a switcher wall wart. Not in a lab where analog stuff happens. I have a special mains connector box in the lab for cases where I have no choice. Very heavily "toroided". One of the first questions I want answered before buying anything is whether it has a built-in power supply.
