And a measurement of the oven's step response
- I used a lab power supply as a current source for the TEC on the oven
- I tweaked the current nob to make a current step
- I looked at the step response
- I used a phone video of the readout on the front of the Newport 3040 to get time stamps b/c it was so easy
- (I will still be hooking up the RS232)
Results
- I get a time constant of 60 seconds
- This is an oven pole frequency of 16.7 mHz
