6 years ago Note to self, measured temp co looks surprisingly good given the DAC's specifications. However, it was only measured at a single voltage, so it's possible that the results are very different at other voltages. Needs more measurements before we make a final decision about whether to include the TECs as a default population option going forward.

[x] Step response/rise time: switch from -10V to +10V and look at output on scope
[ ] Noise spectrum with & without constant DAC updates. Look at +-FS and 0V
[ ] Cross-talk
[ ] Noise with TEC running
[ ] Stability with + without TEC connected
[ ] Small + large signal BW
[x] DC accuracy as a function of duty cycle (self-heating). Ticked off as this is actually quite tricky to measure and I don't expect it to be a large effect at all. Feel free to untick if you really want to see this measured and are willing to take the data!
