CHK7-1012 is intended for use as a simple and precise instrument for measurements of the relative frequency difference of precision crystal oscillators and rubidium frequency standards, calculation of metrological characteristics (Allan variance, RMS, drift etc.) with the mapping process and the measurement results on the external PC or Tablet PC. Software included. It can be equipped with a laptop or Tablet PC.
