Possible GW Instek GDS-1000B hack

<< < (11/52) > >>

rhb:
Just to give some idea of how extremely useful the SA function is here are some more screen dumps.

The H field probe is a 3-4 mm loop of copper wire wound on mandrels to be a push on fit to the probe tip and then insulated with several layers of heatshrink tubing.

The E field probe is a probe tip insulator with a bit of heatshrink over the probe tip.

So nothing fancy or expensive.  But safe to poke around without having to worry about causing a short.

I placed the probe about 1 cm from  the SMPS transformer of my GDS-2072E.  For the H field I rotated the probe to find the max and min orientations.  The E field was taken in the same location.

It's very easy to detect signals on ribbon cables, etc, though some shielding of the transformer fields would be needed to not have that dominate the spectrum.

Nooooo! I've just got back to work after four weeks of paternity and found this disappointing news. Is there anything I can do to help fix this? I've cracked the case on the GDS-2074A scope I have and I'm probing for the JTAG/serial interface as we speak....

Mortymore:
Hope they are OK with this... if not let me know, please.

Summed the parts provided by wgoeo (reply #3) and tv84 (reply #47), and made a "soup" for my 2074E, since I was interested in the Spectrum Analyzer (SA) option.
The "soup" was named lis2.txt, and should be renamed to lis2.html

The SA option was installed with the latest firmware gds2000e_v1.38 (2019-01-26) on the scope.

As rhb explained "To access the SA you need to press the button in the lower right corner of the screen area below the small round button.", the OPTION button. Now I have a use for him.

Hope everything is alright, but it worked for me, as can be seen from the print screens attached.

Thanks for your work

PS: Sorry rhb I had to press AWG button. My scope didn't crash... until I go further, playing with Generators menus that the scope doesn't have.

I updated my 2104E to V1.38, but pressing the 'Option' button the scope says: Not supported for this model!

The OPTION button accessing the SA option, has no direct relation with the firmware version. You have to install the SA license.
