Anritsu

Anritsu offers a comprehensive line of handheld field analyzers, notably under the Site Master, Spectrum Master, and BTS Master series. These battery-operated instruments are engineered for field verification, troubleshooting, and base station maintenance.

Instruments like the Anritsu S331D and Anritsu S331E provide measurements of Return Loss, VSWR, and Distance-to-Fault (DTF), with the Anritsu S331E operating from 2 MHz to 4 GHz. For broader frequency demands, the Anritsu S820D extends microwave cable analysis up to 20 GHz. Handheld spectrum analysis is covered by units such as the Anritsu MS2721B (up to 7.1 GHz), the Anritsu MS2723B (up to 13 GHz), and the Anritsu MS2724B (up to 20 GHz), featuring built-in preamplifiers and resolution bandwidths starting at 1 Hz. Some models, such as the Anritsu S332E and Anritsu S362E, integrate both cable and antenna testing with spectrum analysis within a single field unit.

For impedance and transmission characterization, Anritsu provides both benchtop vector network analyzers (VNAs) and scalar options. The Anritsu 560 is a scalar network analyzer mainframe that relies on external components and signal sources to perform amplitude-only measurements up to 110 GHz.

For full S-parameter analysis, the 37300C Lightning series includes the Anritsu 37369C (40 MHz to 40 GHz) and the Anritsu 37397C (40 MHz to 65 GHz). These 2-port benchtop systems support SOLT, TRL, LRL, and LRM calibrations. For specialized, high-speed applications such as IF filter testing in production, the Anritsu MS4630B offers a 10 Hz to 300 MHz range with a sweep time of 150 µs/point across 3 ports.

Optical fiber deployment and component characterization require specialized analysis tools. Anritsu's ACCESS Master series, including the Anritsu MT9083A, provides portable OTDR capabilities with up to 39 dB dynamic range at 1310 nm. Benchtop optical spectrum analyzers (OSAs) like the Anritsu MS9710C and Anritsu MS9740A cover the 600 nm to 1750 nm wavelength range for active and passive device evaluations.

For transport network testing, the Anritsu MP1570A/A1 and Anritsu MP1590B serve as modular mainframes for SDH, SONET, PDH, and ATM protocol testing. The Anritsu MP1590B supports network performance and jitter analysis at optical line rates up to 11.1 Gb/s.

Anritsu's signal generation systems include the Anritsu MG3692B synthesized signal generator (2 GHz to 20 GHz) and the Anritsu 68369B sweep generator (10 MHz to 40 GHz), both suited for local oscillator substitution. For mobile communication modulation testing, vector signal generators like the Anritsu MG3681A provide carrier frequencies up to 3 GHz with digital modulation capabilities.

Power measurement is handled by instruments like the single-input Anritsu ML2437A and dual-input Anritsu ML2438A. Both models achieve sampling rates of over 35,000 readings per second and support various thermal and diode-based MA-series sensors.
