Time & Frequency Parameter/Equipment Range CMC 2, 4, 7 (±) Comments Frequency – Measure 100 mV to 750 V 20 Hz to 300 kHz 0.02 % Keysight 34465A ___________________________________________________________ 1 This laboratory offers commercial calibration service. 2 Calibration and Measurement Capability Uncertainty (C MC) is the smallest uncertainty of measurement that a laboratory can achieve within its scope of accreditation when performing more or less routine calibrations of nearly ideal measurement standards or nearly ideal measuring equipment. CMCs represent expanded uncertainties expressed at approximately the 95 % level of confidence, usually using a coverage factor of k = 2. The actual measurement uncertainty of a specific calibration performed by the laboratory may be greater than the CMC due to the behavior of the customer’s device and to influences from the circumstances of the specific calibration. 3 CMC is computed based on direct reading in W. 4 The type of instrument or material being calibra ted is defined by the parameter. This indicates the laboratory is capable of calibrating instruments that measure or generate the values in the ranges indicated for the listed measurement parameter. 5 This scope meets A2LA’s P112 Flexible Scope Policy. 6 The stated measured values are determined usi ng the indicated instrument (see Comments). This capability is suitable for the calibration of the devices intended to measure or generate the measured value in the ranges indicated. CMC’s are expressed as either a specific value that covers the full range or as a percent or fraction of the reading plus a fixed floor specification. 7 In the statement of CMC, percentages are per centage of reading, unless otherwise indicated.
