I measured the current noise of our Thorlabs ITC502 laser driver today.
While in EE, I
I'm ordering a few electronic parts. Please add to this list if there's more I should pick up from DigiKey for EE.
Also came in today to look for connectors, heat pads, heat sinks, box, etc for putting PSOMA's fiber optics in a box (+ EOM RF / DC bias).
Chub dropped off a repaired Marconi 2023A signal generator, which I'm phase locking to a function generator to test out how it will go in my three corner hat measurement. Perhaps I could synchronize between the Moku phasemeter frequency estimate (of f_13, f_23) and Marconi frequency estimate (f_12) offline by introducing a time offset to f_12 and maximizing the correlation with f_13 and f_23?
Here's what I did. See attachment 1 for configuration.

The following books were added to the EE shop. Do not take them without first returning them.

I took 12 soldercup DB9 connectors from the EE shop for use in 40m. Here is the link of what we took:|
There are still 5-10 connectors left but this should be restocked soon. The above item is not in stock at digikey so an appropriate replacement should be chosen.
I replaced the Laser Warning light for Cryo lab with a LED bulb, rather than the existing CFLs. There is a pack of such replacement bulbs now in the big grey cabinet in the EE lab.
