Indeed! Yup im using it to monitor the frequency of external sources...though what is very interesting to me (and as other people in this thread have pointed out) is that if you wire the output into the EXT_IN, the value of the input and output don't agree! For example, you set the generator to "sine wave" at 10 Mhz and read that signal on the EXT_IN, and you will see something like 10.000123...so the counter and generator don't agree, even though they are presumably running on the same clock! Not sure why this is, maybe someone who knows more about FPGA/signal generators can comment...
Hi, I´m new in this forum.
I just bought one of this sets (KKmoon...) mainly as acounter and I could need some help.
I am repairing a wallclock , the pendulum is swinging with 0.86666666 Hz T = 1,153846s.If I want to adjust the pendulum for qanerror of 1s per day I need a resolution of 12ppm, or I have to wait many hours for the next adjustment.
With the period measurement I am not really successful because the periods are not consistant, depending on the accuracy of the cowheels and mainly of the escapement wheel which has 26 teeth. I would have to measure at least 26 periods or better a multiple of that. At the moment the 5th digit is changing continuously.
To read out aall results would help, so I could do the averaging in Excel
thanks in advance
