I recently bought a PTOC32227 OCXO (datasheet) from eBay (secondhand). It is supposed to output a square wave at 10MHz. However, it is a part of a bigger circuit that is not working properly and it seems to me that the failing component may be the OCXO.
I took it apart from the rest of the board, and connected its VS pin to +5V, GND to ground and measured the HF pin with an oscilloscope (left the VC pin not connected). This is the output:
Shouldn't it be an square wave? How can I determine then if the OCXO is working properly?
Edit: my oscilloscope BW is 100MHz, so it should not be a problem in the measurement
Edit 2: new measurements with my probe in x10 mode seem fine! Thanks!
