Re: OCXO OSC5A2B02 10.000 MHZ

I purchased this one:
https://www.ebay.com/itm/1-USED-CETC-CTI-OSC5A2B02-10MHz-5V-26-26-12-Square-Wave-OCXO-Crystal-Oscillator/332389156868?hash=item4d63f00804:g:5VIAAOSwruVZxm6k

I took a 5K pot, connected high side to +5V, low side to GND, wiper to the control pin. I let the OXCO warm up for a couple of hours. Using a rubidium standard, I calibrated my frequency counter to 10.000000 MHz. I then connected the OCXO to the counter and adjusted the pot to 10.000000 MHz. I initially tried a 10K pot but it was critical to adjust which is why I went to 5K.

I could have used my scope in XY mode like Chuck does, but it is packed away and I didn't want to dig it out.
