I have created a new tektronix-ocp2k5 driver for TBS1000B/EDU, TBS1000, TDS2000C/TDS1000C-EDU, TDS2000B/TDS1000B, TDS2000/TDS1000, TDS200 and TPS2000B/TPS2000 Series Digital Oscilloscopes. I tried to find a proper name for this protocol, but Tektronix support was being squirrely about a name, so I just arbitrarily came up with the blandly-generic "oscilloscope control protocol 2k5" as that is the only words somewhat used to describe it in the programming manual, plus the size of memory of all of these devices. I also thought about calling it the "lem2k5" for "Low-end Millennium" as this protocol seems to emerge around the turn of the millennium in low-end scopes with the TDS200 series. I'm happy to oblige a name change to something else.
I have verified it using a TDS2000B series scope <https://sigrok.org/wiki/Tektronix_TDS2000B_series>. A lot of features aren't supported, but I think the critical ones are taken care of. Luckily, since it appears that local control isn't locked out, more advanced features can still be configured via the front panel. The most glaring example of this is the trigger voltage, which PulseView doesn't seem to support. I didn't update the udev rules, but I am querying the vendor for all the relevant PIDs. I have opened a github PR here: https://github.com/sigrokproject/libsigrok/pull/213 The branch itself is here: https://github.com/byteit101/libsigrok/tree/tek_tds2000b Note that the branch is based on the sigrok.org master, not the out-of-date github master. There are some additional screenshots on the github PR. Thanks, Patrick
