Frequency Measure IP is an algorithm IP that measures frequency and period of the periodic signal by the frequency counter.
By using this IP, the following electrical characteristics for target devices can be measured and evaluated easily.
- Frequency measurement of the output clock of device
- Characterization of the PLL circuit
- Characterization of the VCO circuit
- Quality inspection of the crystal oscillator
In addition, by using Multipoint Measurement Plugin, It is easy to measure and evaluate characteristics such as measurement value fluctuation of multiple measurements / maximum value / minimum value / average value / variation for the above measurement.
