1212..22 CalibrationCalibration
MT1000A, MU100010A, MU100011A, and MU100090A do not require any
calibration in the meaning of adjustment after shipment from factory.
When the MU100090A is capturing GPS satellites, built-in Rubidium oscillator
is disciplined to the UTC by using the GPS signal. By this operation, 10 MHz
clock and 1PPS are adjusted. The MU100090A 1PPS and 10 MHz are
disciplined to the UTC to align it with the standard second.
When the reference 1PPS is available, the 10 MHz clock and 1PPS can be
adjusted by inputting the reference 1PPS to the 1pps Sync In connector.
In order to ensure measurements made by these instruments are within
specifications, Anritsu recommends performance test of the instrument for
quality assurance. The recommended frequency depends on the particular
usage of the instruments, but generally yearly performance test is highly
advised.
The final decision on performance verification frequency is to be taken by the
user, as performance test verifies past measurements rather than guarantee
future measurements.
In the event of this equipment malfunctions, contact an Anritsu Service and
Sales office. Contact information can be found on the last page of the printed
version of this manual, and is available in a separate file on the PDF version.
