Requirements: View

This program uses a data acquisition system timing controller chip (DAQ-STC) to measure the frequency of a periodic analog signal. You use the onboard analog trigger circuitry and the DAQ-STC to measure the digital output frequency. However, this program only works for E Series and 61XX devices with analog trigger circuitry.

To determine if the device you are using supports analog triggering, refer to the trigger specifications of the device user manual.
