I found MSP430FR604x which seem as very good candidates for precise frequency measurement rather than regular MCUs which are slow (nanosecond resolution). I would like to hear your opinion to this measurement requirements.
I need to measure frequency ranging 1-2 MHz of a square signal with averaging over the period of 50 usec.
time measurement resolution: <1ns
period of one measurement: 50 usec
I need to measure frequency from number of edges of input square wave signal during this period (50 usec).
I would use MSP430FR604x as described: High-precision time measurement resolution of <5ps
Q1: Can MSP430FR604x be used for such measurements?
Q2: Is there any working example for similar pulse signal measurements?
Q3: How does MSP430FR604x measurement method works?
Thank you for any help.
