Anritsu 54111A – Network Analyzer; 1 MHz to 3 GHz

The Anritsu 54111A is a scalar network analyzer covering 1 MHz to 3 GHz, engineered to characterize complex reflection and transmission behavior of RF components with high directivity and measurement precision. This synthesized-frequency source instrument delivers magnitude, phase, group-delay response, return loss, SWR, and distance-to-fault analysis across a wide range of two-port devices.

– Technical Specifications

– Key Features

The 54111A delivers accurate RF characterization through its crystal-stabilized source and multi-parameter measurement suite. The instrument supports customizable display and measurement setups for flexible test configurations. Internal RF attenuation capability (Option 2) extends dynamic range to 70 dB for demanding applications.

– Typical Applications

The 54111A characterizes amplifiers, antennas, attenuators, cables, filters, adapters, RF bridges, duplexers, couplers, waveguide transmission lines, isolators, circulators, mixers, receivers, transceivers, up/down converters, multiplexers, power dividers, VCOs, switches, and related RF/microwave devices.

– Compatibility & Integration

GPIB connectivity enables integration into automated test systems and remote operation. The instrument is part of the 54100A series family. Rack mounting with slides and 90-degree tilt capability is available (Option 1). External power measurement requires Anritsu power sensors—MA4601A for 50Ω or MA4603A with J0365 connector for 75Ω applications, paired with the ML4803A Power Meter.
