@Ice-tea: any chance to open the front of one of those display-less SMIQs you have and take a picture of what it looks like inside? I'm planning on doing a TFT conversion for the SMIQ I have here and I'm wondering what is missing from the display-less SMIQs you have. This will be a long term plan though but maybe I can turn this into a product.



If you need more, let me know. Or, feel free to drop by ;)

Yeah, another boring handheld DMM.  For $100 (which is what it sells for around here) this is a mediocre example of the art; however, when you stumble upon a mint example in a pawn shop for $30 with case and leads, not so bad.  I checked it with my voltage and resistance "standards" and it's acceptably close; something to keep in my travel kit when helping out a friend or shopping for higher end stuff.  ;)

It also has low-Z mode, a 40 mΩ range, relative, min/max, µA and separate low/high current jacks, which is decent for a cheapie.

This is the top panel. I'm interested in what is inside the front panel model (where the display and the buttons are).
There are small lies, big lies and then there is what is on the screen of your oscilloscope.

Can you remove the CPU board to take a picture of what is underneath it?

Metal plate. Nothing much else.

I forgot. You should remove that plate as well (just pull it out). There should be a board in there for the front panel keys. I'm interested to see how the display-less models are prepared for a display.

Thanks! It seems they just left the display and the backlight inverter out. The idea I have for a TFT conversion is to connect it parallel to the existing front panel board. The ribbon cable between the front panel and CPU board seems long enough to add an extra connector.

Just wondering.. what are you missing by not having a display? Seems easy enough to use the keys for most functions?

Without the display you don't see what you are doing. For example: the SMIQ can do sweeps. I don't see how you can set these up with just the keys. And then there is self-calibration. How are you sure there are no self test errors?

I assume errors can be read through GPIB?

I don't know. If all is well your SMIQs should also have a serial port which might be easier to use. You can type commands using a terminal emulator (like Hyperterminal) on your PC. A common problem seems that the backup battery is flat which causes the SMIQ to lose the self adjustment values. In turn this can cause several other errors and weird behaviour.

Yeah, I have a SMIQ03 that probably has that issue. Might make a good test case to see if those problems can be read remotely.

An Electronic Load from Ebay for 25 € plus shipping . Sold as unknown status but works fine after cleaning the board from solder splatter and some small mechanical issues .  :)

At least it wasn't in unknown status due to not providing power output. :-DD

Very nice HP 8566A. My plan is to track down the parts I need to convert it into a B RF section.

About that.  :-DD I don't have a scale handy, but from a purely qualitative standpoint the 8566 RF section is MUCH heavier than the 8568 RF section.

Yeah the thing is hefty, i think i remember the thing being around 50 kg (110 lb) all together. So they had a very good reason to split it into two boxes, even just lifting half of it takes a good bit of effort.

The HP engineers that worked on it called it the "doomsday spectrum analyzer" and was for a good time among the highest performance spectrum analyzers in the world.
