Anritsu ME538M Microwave System Analyzer

The Anritsu ME538M Microwave System Analyzer is a link analyzer engineered for installation, commissioning, and maintenance of microwave transmission systems. It measures baseband and intermediate frequency characteristics across terrestrial microwave radio relay and satellite communication networks, delivering signal quality verification, system alignment, and transmission path loss analysis.

Technical Specifications

• Frequency Range: 70 MHz and 140 MHz IF bands


• Baseband Frequencies: Nine selectable BB frequencies; three low frequencies determined by model designation (K, L, or M)


• Level Range: 0 to 16 dBm


• Impedance: 50 ohm


• Weight: 68 lbs (31.0 kg)

Key Features

• Dual-channel transmitter and receiver configuration with independent measurement paths


• Transmitter front panel features LED readout for deviation, sweep width, and center frequency settings


• Receiver provides automatic settings and display for deviation, IF level, baseband frequency and level, calibration, and attenuation


• CRT and large LED displays for simultaneous multi-parameter visualization


• Built-in microprocessor enables auto ranging, peak-to-peak deviation measurement via P-P pushbutton, and parameterized measurement selection


• Signal averaging through internal normalizing circuitry to suppress noise in satellite and high-noise environments


• Automatic CRT calibration and centering via AUTO pushbutton function


• Direct trace subtraction to isolate system response from measuring instrument components


• Optional BB-to-BB amplitude measurement for end-to-end link characterization in FDM-FM telephone and television networks


• Automatic scale and unit display for all measurements


• Optional X-Y recorder interface with front-panel control


• GP-IB receiver interface supporting direct measurement plotting

Typical Applications Terrestrial microwave radio relay systems, INTELSAT satellite communication links, and FDM-FM relay networks requiring transmission quality verification and maintenance diagnostics.

Compatibility & Integration The ME538M integrates with existing microwave test benches via GP-IB interface and external recorder connectivity. Option 04 configuration available.
