Keithley DMM7510, SMU 2450 & 2460 problems

(1/29) > >>

HighVoltage:
The new Keithley instruments are really great, when they work alright. But ...

My DMM7510, the SMU 2450 and 2460 all suffer from time to time of several problems.

1. "Blue Screen of Death"
2. Not responsive to any button

I have contacted Keithley / Tektronix Germany but was not offered any help.
There is a hope that this will be fixed with any future FW update but who knows.
I was told by Keithley Germany, that this is a single incident, that only I have these problems and Keithley is not aware that others have these problems too.

The latest FW Version: 1.6.1a is installed
Release Date: Aug 23 2016 - 12:00 am

I have heard from other people here in the eevblog forum, that they have similar issues / problems.
May be we can help Keithley by compiling all problems in this thread and hope they can use it to fix everything in a new FW update.

So, if you have encountered any issues with your new Keithley instrument as well, please post them here.

Blue Screen Error Codes (so far detected)

- PC=0003D660
- PC=0003D661

FW=1.6.1a on both my 7510 and 2450.

I've seen both issues you list above with #2 being very common.  I can easily trigger #2 by navigating the graph tabs via the instrument's web interface.

We should add a line item for maxwell3e10's noise discovery:

During a quasi non-responsive time I managed to catch this before it fully locked up:

maxwell3e10:
1. Confirm blue screen with latest firmware

2. When using trigger programming from front panel to arrange for timed measurements, the meter stops triggering after some random number of samples.
 
3. Not a bug, but when saving buffer to USB, the meter does not check for existence of a file with same name, instead, it just always asks to confirm saving file.

4. Most directly dealing with performance, the autozero does not effectively remove flicker noise on DCV 10V scale for continuous measurements on time scales of 1-50 sec, as illustrated in figures below. As the result on 10V DCV scale the noise performance of DMM7510 is significantly worse than Keysight 34465A.

Wow, I would not have expected this from Keithley. I realize that every brand can release a software with some issues left, but then I would expect them to at least acknowledge these and assure the customer they are working on a fix for the next firmware release. Especially because it seems it not very difficult to trigger the fault…

Still, I think their gear looks really fantastic, and would love to have your setup (with our without problems). But for the moment I do to little development to warrant that kind of cost…
