In-Circuit Crystal Frequency Measurement
Since you have an external crystal, not an external crystal oscillator, it is extremely sensitive for connecting any measurement equipment to it. External crystal oscillator outputs logic level square wave and it would be much easier to measure.
The frequency is too high to measure with your DAQ directly, it would be necessary to write a test program to PIC that outputs a divided down logic level signal based on the crystal frequency.
It still would not tell how good the crystal circuitry is. It might still be barely oscillating or have startup issues due to some manufacturing error like missing or wrong parts in the crystal circuitry.
