--- Quote from: med6753 on May 23, 2018, 11:01:43 am ---Decided to put the B&K 2120 scope to use rather than put it in storage. I connected it into the audio system reminiscent of those fancy audio scopes sold back in the 1970's. Yea, it's campy and doesn't really serve much function other than to impress the unwashed masses with dancing green lines. They can enjoy display of discrete left and right channels (Pix 1) or the X/Y "fuzzball" display (Pix 2). Pix 3 is an overall view of the entire system.
Yep, I'm odd. :-DD :-//

I had almost the same exact relationship with the old Hitachi V-212 I fixed a couple months ago; I no longer needed it for a work beater, and it was so damned, insufferably valiant after all the abuse I put it through that I just didn't have the heart to get rid of it.
So it sat on the corner of my bench permanently connected to a simple curve tracer where it got used a few times a month. But it WAS nice to have it just sitting there ready to use; I found I used it a lot more than if I had to drag out my curve tracer and hook it up/set up the scope/etc. For a while I toyed with the idea of building the tracer inside of it; there's a LOT of empty space inside the V-212.
I suppose it could still happen. :-DD

Well I thought that maybe the short on the power to the cmos ram might have taken out the diode when the short occurred, nope thats all fine and so I checked the supplies, horror :scared: it looked like the analogue side was not getting its power, digital side was perfect :-//. Then it dawned on me that it might have its own ground, isolated from the digital and bingo, it has and all voltages are correct :phew:.
So the question is, did they know how to calibrate this after all? So now I'm going to try and see what I can do with it, more later if penis fingers can keep away this time :-DD
EDIT:
Just noticed that cal selector switch is not in the correct position, could it be...surely not,,,surely they must of noticed it??? :-//

Yes, it does, the meter is reading DC fine, connected it up to my MS7221 and set it to .1mV and the 3478A displays 00.0001V spot on. Set it to DCA, set MS7221 to 0.010mA and 3478A comes right back with 0.00001A, again spot on
On my AD584-M I get the following results
2.5V 5V
7.5V 10V

Bet you a dollar after your conversation re: the Fluke calibration software, they found that they HAD the right software modules, and after a little digging, ALSO had the correct cabling to do the cal via the GPIB. Wouldn't be surprised if they didn't need to move the switch to do it that way either. Probably all the techs who actually knew how to use the software had already retired or moved on to better-paying jobs.

Says in the manual it won't talk cal data to HP-IB if the cal switch wasn't turned.
I bet they employ fucktards.

Well it certainly seems to be perfectly calibrated so far, just going to check resistances and ACV and ACA. Strange that the display still flashes uncalibrated when switching on? Did I mention it was FOC?
