The BTS Master loads factory calibration data during start‑up, eliminating the need for daily calibration checks. In WCDMA modes, an additional automatic calibration is performed as the internal temperature of the BTS Master changes (to insure the best possible measurement results).

Although the BTS Master does not require daily field calibration, Anritsu Company recommends annual calibration and performance verification by local Anritsu service
centers. The Cable and Antenna Analyzer requires calibration standards for OPEN,
SHORT, and LOAD, which are sold separately. The Cable and Antenna Analyzer Measurement Guide is available on the documentation disc and the Anritsu web site.
Refer to Measurement Guides, for a list of measurement guides and their Anritsu part numbers.
