Reverse engineering Tektronix TDS3GV module for TDS3000 series oscilloscopes?
pmercier:
Done some testing on the pins with pull-up/pull-down resistors and nothing appened. No bugs, no freeze and no card detection. :phew:
I think i'll stop this brute test because it mean turing on turning off the socilloscope every time and with more than 500K combinations i'll end up with a dead finger and a broken oscilloscope :scared:
Time to :
- JTAG on the A model ?
- repair the PSU of the C model ?
- repair the battery pack of the C model ?
:-/O
Hairystuff:
Not sure if this information is of any use to you guys but I found that if you use the TDS3ENG Application Module it enables the communication configuration options blindly in the utility sub menu.
pmercier:
Good to know, thank you !
Time to find some eeprom :)

Oh maybe that's why they were all enabled on mine. I reflashed the Adv Trig module that came in mine since the latest firmware enables that by default anyway. I've actually considered reflashing both modules I have with features I actually want, because TDS3ENG enables a whole bunch of completely useless crap that clutters up the menu. I don't have (or need) the hardware necessary to test SDI video and I have no use whatsoever for the ability to measure a bunch of obsolete communication protocols.
Hairystuff:
The comms protocol masks where kind of useless to me and the video stuff is nice to have especially the vector scope stuff but the video display stuff is not the best performance wise, I was hoping there would be some CAN/serial/I2C decoding ability but I'm not too fussed, I'm hoping that the ENG application module might enable the serial ports so that the scope can be hacked to full bandwidth without the comms/ethernet module on a non 3012B/C scope, I've never really needed anything above a 100MHz but it would be interesting to see what uses I could find for it at 500MHz.
