4.3.11 Calibration of measuring equipment.
equipment and accessories required for measurement in accordance with this
standard shall be calibrated in accordance with ANSI/NCSL Z540-1 or ISO
10012-1 or under an approved calibration program traceable to the National
Institute for Standards and Technology. In particular, measurement antennas,
current probes, field sensors, and other devices used in the measurement loop
shall be calibrated at least every 2 years unless otherwise specified by the
procuring activity, or when damage is apparent.
22.214.171.124 Measurement system test.
At the start of
each emission test, the complete test system (including measurement
receivers, cables, attenuators, couplers, and so forth) shall be verified by
injecting a known signal, as stated in the individual test procedure, while
monitoring system output for the proper indication. When the emission test
involves an uninterrupted set of repeated measurements (such as evaluating
different operating modes of the EUT) using the same measurement equipment,
the measurement system test needs to be accomplished only one time.
