Tektronix DPO7200xx and AWG70000A — Convenience Methods for Waveform Workflows

[Benn Thomsen (bennthomsen)]

Adds convenience methods to the Tektronix DPO7200xx oscilloscope and AWG70000A waveform generator drivers to
streamline triggered acquisition and sequence upload workflows.

Files changed: 4 files, +133 / −2 lines

##DPO7200xx Oscilloscope
(DPO7200xx.py, +58 lines)

Three new convenience methods on TektronixDPO7000xx:

• single() — puts the scope into single-acquisition mode, starts a run, and polls until both the acquisition
  completes and the trigger is ready (with timeout)
• download_waveforms() — waits for acquisition to finish, then downloads waveform traces from all enabled channels
• get_timebase() — returns a tuple of (time unit, time axis array) from the first channel

##AWG70000A Waveform Generator
(AWG70000A.py, +26 lines)

One new convenience method on TektronixAWG70000Base:

• upload_seqx() — builds a .seqx file from input, uploads it to the AWG, loads it into playback memory, assigns
  tracks to channels 1 & 2, enables outputs, and starts playback

Other Changes

• Station.ipynb — minor fix: updated import path from qcodes.utils.installation to qcodes.extensions

Benn Thomsen (@benn-thomsen) Thanks, In qcodes we require that the code should contain types for all input and output. I have added comments with most of them but please check that this is correct.
