CMC ( Calibration & Measurement Capabilities)

1. Time Scale Different
  Officially the laboratory does not provide this measurement services. However, laboratory facilities are quite adequate to measure time different in ns level to UTC(KIM). However, the laboratory guarantee only 5 ms uncertainty to UTC

2. Time Interval
  In general, the laboratory has a capability to generate 1 ms to 10 s time interval marker, and measure interval down to 100 ps, in the form of pulse-width, pulse train marker, or separate start-stop markers.
The laboratory also capable to measure a time interval between two events of a signals or separate two signals identified by a voltage threshold crossing, in the range of -2.5 to + 2.5 V.
The Measurement Uncertainty is guaranteed  in the level of ns.

3. Frequency
  The laboratory provides calibration services for Reference Frequency Source, like Rubidium or Quartz Frequency Standard which generates frequency of 5 or 10 MHz. Theoretically, Frequency Test & Measurement Instruments and Synthesized Generators accuracy are based on the uncertainty of its time base oscillator, which is usually produce 10 MHz of frequency. So, calibration is conducted mainly by measuring this frequency. However, laboratory will be ready to generate up to 20 GHz for conventional input test, and to measure up to 3 GHz to satisfy the customer needs with the accuracy nearly equal to that of the NaFS base frequency ( < 1E-12 ).

These capabilities has been peer-evaluated by APMP-TCTF nominated evaluator, in conjunction with the laboratory quality system assessment, provided by KAN
