Resolution The MS2668C has a full complement of frequency counter functions. The resolution is ±1 Hz max. even at full span, supporting highspeed frequency measurement. The high sensitivity compared to ordinary counters makes it easy to select one signal from many and determine its frequency

When using a frequency counter to monitor the CNT output pulse rate, a counter with a DC coupled input must be used. The CNT output is a return-to-zero signal whose duty cycle varies from zero to fifty percent, from minus full scale to positive full scale acceleration
