/*
* Generic Siglent scope driver. Currently supports SDS2000X+ and SDS1104X-E.
* This file was originally derived from the LeCroy driver but has been modified extensively.
* Note that this port replaces the previous Siglent driver, which was non-functional. That is available in the git
* archive if needed.
*
* SDS2000/5000/6000 port (c) 2021 Dave Marples.
* Tested on SDS2000X+. If someone wants to loan an SDS5000/6000A/6000Pro for testing those
* can be integrated and the changes required should be limited.
*
* Starting SDS1x04X-E port (c) 2021 Dannes and Stefan Mandl
* Using Programming Guide PG01-E02D an Firmware 6.1.37R8
* Tested on SDS1104X-E. Should also support SDS10000CML+/CNL+/Dl+/E+/F+, SDS2000/2000x, SDS1000x/1000x+,
* SDS1000X-E/X-C but these are untested. Feedback and/or loan instruments appreciated.
*
*
* Current State
* =============
*
* SDS2000XP
*
* - Basic functionality for analog channels works.
* - There is no feature detection because the scope does not support *OPT? (Request made)
* - Digital channels are not implemented (code in here is leftover from LeCroy)
* - Triggers are untested.
* - Sampling lengths up to 10MSamples are supported. 50M and 100M need to be batched and will be
* horribly slow.
*
* SDS1104X-E
*
* Using Programming Guide PG01-E02D and Firmware 6.2.37R8
* receive data from scope on c1 c2 c3 c4
* set EDGE Trigger on channel
* using 4 Channels ( 70 kS 25 MS/s) got 4,23 WFM/s
* using 4 Channels ( 700 kpts 100 MSa/s) got 1,62 WFM/s
* using 1 Channels ( 1.75 Mpts 250 MSa/s) got 2,38 WFM/s
* using 4 Channels ( 3.5 Mpts 500 MSa/s) got 0,39 WFM/s
*
* TODO Click "Reload configuration from scope" sometimes we loosing WAVE rendering ( threading issue ?)
* TODO sometimes socket timeout (Warning: Socket read failed errno=11 errno=4)
*
* Note that this port replaces the previous Siglent driver, which was non-functional. That is available in the git
* archive if needed.
