Refer to the Technical Data Sheet listed in Introduction for general specifications, detailed measurement specifications for all available measurement modes, ordering information, power sensors, and available accessories. The data sheet is included with the instrument and is available on the Anritsu web site:

The Spectrum 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 Spectrum Master changes (to insure the best possible measurement results).
Although the Spectrum Master does not require daily field calibration, Anritsu Company recommends annual calibration and performance verification by local Anritsu service centers.
Spectrum Master preventive maintenance consists of cleaning the unit and inspecting and cleaning the RF connectors on the instrument and on all accessories. Clean the Spectrum Master with a soft, lint‑free cloth that is dampened with water or with water and a mild cleaning solution.
Clean the RF connectors and center pins with a cotton swab dampened with denatured alcohol. Visually inspect the connectors. The fingers of N(f) connectors and the pins of N(m) connectors should be unbroken and uniform in appearance. If you are unsure whether the connectors are good, then gauge the connectors to confirm that their dimensions are correct.
The Spectrum Master, like other high performance instruments, is susceptible to ESD (electrostatic discharge) damage. Coaxial cables and antennas often build up a static charge, which may damage the Spectrum Master input circuitry (if allowed to discharge by connecting directly to the Spectrum Master without previously discharging the static charge). Spectrum Master 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 Spectrum Master, Anritsu Company recommends that any static charges that may be present be dissipated before connecting coaxial cables or antennas to the Spectrum Master. This may be as simple as temporarily attaching a short or load device to the cable or antenna prior to attaching to the Spectrum Master. 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.
