1-6 Calibration Requirements
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
Appendix A, “Measurement Guides” , for a list of measurement guides and their
Anritsu part numbers.
1-7 ESD Cautions
The MT8221B, like other high performance instruments, is susceptible to ESD (electrostatic
discharge) damage. Coaxial cables and antennas often build up a static charge, which
(if allowed to discharge by connecting directly to the MT8221B without discharging the static
charge) may damage the MT8221B input circuitry. MT8221B operators
must be aware of
the potential for ESD damage and take all necessary precautions.
Operators should exercise practices outlined within industry standards such as JEDEC-625
(EIA-625), MIL-HDBK-263, and MIL-STD-1686, which pertain to ESD and ESDS devices,
equipment, and practices. Because these apply to the MT8221B, Anritsu Company
recommends that any static charges that may be present be dissipated before connecting
coaxial cables or antennas to the MT8221B. This may be as simple as temporarily attaching a
short or load device to the cable or antenna prior to attaching to the MT8221B. Remember
that the operator may also carry a static charge that can cause damage. Following the
practices outlined in the above standards ensures a safe environment for both personnel and
equipment.

Note

temperature (~15 minutes) before calibrating.
