Hello,
I want to count TTL pulses from an APD using PCI 6602 counters and Labview.I have gated the APD signal using an external clock.I I generated this signal using PCI it has 2.5microsecond on time and 0.5microsecond off time.Then I am counting the pulses at the counter from APD and write it in a file.I am using a queue structure to do this.The VI seems to work fine without error but the values of the pulses counted keep on increasing I don't understand why this is happening.I think the values are just garbage value or may be cummulative values.Does the counter in PCI give cummulative values?I am confused.I have my VI below.Please help!
