Tool/software:
Hello,
I am using the TDC7200EVM and the MSP430 Launch Pad to measure time intervals.
I am trying to connect the TDC to an external clock reference of 10 MHz through the CLK_EXT SMA connector. However, when I start the measurements, the GUI freezes and the measurements are not performed (files are empty).
I already moved the jumper such that CLK_EXT is connected to CLK_EST instead of the internal oscillator at Y1.
The only time the measurements are performed is if I move the jumper back to connect Y1 at J2 and CLK_SEL. However, the measured delay is incorrect as it scales it to the internal 8 MHz reference. E.g. if I want to measure a delay of 19 microseconds with the 10 MHz external clock, it will now tell me the delay is 15 microseconds. I am using the STAET and STOP signal as specified in section 6.1 in the TDC7200EVM User's Guide.
Here is more info about my GUI configuration:
To generate the 10 MHz external clock reference, I use a synthesizer to generate a squared signal with 50% duty cycle, and 3.3 V. I tried using a 50 Ohm impedance but nothing changed.
Can someone help me figure out why the GUI won't perform measurements when the jumper is moved to the configuration in the image above?
Thank you in advance!
