# Anritsu S820A 3.3 GHz to 20 GHz Microwave Transmission Line and Antenna Analyzer (Pre-Owned) # Anritsu S820A 3.3 GHz to 20 GHz Microwave Transmission Line and Antenna Analyzer (Pre-Owned) ## Key Features At A Glance - Broadband 3.3 GHz to 20.0 GHz coverage for microwave transmission line and antenna analysis - One-port return loss/SWR (0 to 54 dB) plus Distance-to-Fault on both coax and waveguide - Precision K female 50 Ω test port; +22 dBm maximum input without damage at the test port - RS-232C 9-pin D-sub serial interface for PC transfer and Site Master Software Tools database management - Stores up to 70 traces and 6 instrument configurations with calibration in internal memory - Frequency synthesizer accurate to 75 ppm (CW mode) with 1 MHz resolution - Optional Option 5 RF Watt Meter power monitor (–80 to +80 dBm display range) - Portable 1.14 kg unit with immunity to live-site interfering RF signals up to −10 dBm The Anritsu S820A is a portable, one-port microwave transmission line and antenna analyzer in the Site Master line, using frequency domain reflectometry to improve quality and reduce maintenance expense. Covering 3.3 GHz to 20.0 GHz, it extends the Microwave Site Master family frequency range to 20.0 GHz and provides a convenient field method to measure, troubleshoot, and verify transmission line and antenna systems in place of a laboratory-sized scalar analyzer or microwave test set. The S820A targets microwave site installers, point-to-point operators, radio manufacturers, PCS/Cellular operators, and utility companies that support microwave links. Its main application is to test and measure the full 18 GHz radio frequency band (17.7 to 19.7 GHz) microwave waveguide and antenna system, making it suited to commissioning and maintaining microwave link infrastructure in the field. ValueTronics stocks and holds its own inventory in a 20,000 square foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. Every pre-owned unit is inspected and functionally verified in-house before it ships, while new units ship factory-sealed exactly as received from the manufacturer. Holding inventory directly lets the team confirm what is on hand and match the right instrument to an application quickly. ## Brand Heritage Anritsu Corporation expanded its microwave measurement business through its 1990 acquisition of Wiltron Company in the United States. The Wiltron name was retired in 1997, when that operation was rebranded as Anritsu Company, consolidating the microwave product lines under the Anritsu name. ## Accessories Supplied - User's Guide - Soft Carrying Case - AC-DC Adapter - Precision Adapter, Ruggedized K(m) to N(f) - Automotive Cigarette Lighter/12 Volt DC Adapter - CD ROM containing Fault Location (DTF), Smith Chart and Software Management Tools - Serial Interface Cable - One Year Warranty ## Product Core & Specifications Specification Value Frequency Frequency Range 3.3 to 20.0 GHz Frequency Accuracy (CW mode) 75 ppm Frequency Resolution 1 MHz Immunity to Interfering RF Signals up to −10 dBm Return Loss (SWR) Range 0 to 54 dB (1 to 65) Resolution 0.01 dB (0.01) Distance-to-Fault Vertical range, Return loss 0 to 54 dB Vertical range, SWR 1 to 65 Horizontal range (meter) 0 to 129X (resolution) Horizontal resolution (meter), coax (1.5 x 10⁸)(νρ)/∆frequency (Rectangular windowing) Horizontal resolution (meter), waveguide (1.5 x 10⁸)√1 – (fc/f1)²/∆frequency Wattmeter (RF power monitor, Option 5) Display range –80 to +80 dBm, 10 pW to 100 kW Detector range –50 to +20 dBm, 32 nW to 100 mW Offset range 0 to +60 dB Resolution 0.1 dB, 0.1 x W Coax/Waveguide Insertion Loss Range 0 to 54 dB Resolution 0.01 dB Test Port Test port connector Precision K female, 50 Ω Maximum input without damage K(f) test port +22 dBm RF power detector +20 dBm, 50 Ω Memory Trace memory 70 Instrument configuration/calibration 6 Temperature Operating 0 to 50°C Storage –20° to 75°C General Weight 1.14 kg nom Size 203.2 mm x 177.8 mm x 57.2 mm Electromagnetic compatibility Meets European community requirements for CE marking. RS232 9 pin D-sub, three wire serial > **Important:** Maximum input without damage: +22 dBm at the K(f) test port; +20 dBm at the RF power detector (50 Ω). > **Important:** All specifications apply when calibrated at ambient temperature after a five minute warm up. > **Important:** The Option 5 RF Watt Meter Power Monitor does not include the RF Detector; an RF detector (e.g., 560-7N50B, N(m), 50 Ohm, 10 MHz to 20 GHz) must be ordered separately for the wattmeter function. > **Important:** Immunity performance (−10 dBm) represents a typical worst-case condition measured in CW mode; immunity is typically better when swept frequencies are used. > **Important:** The Site Master Software Tools supplied with each S820A operates with Windows 95, Windows 98 and Windows NT. ## About this Pre-Owned unit This pre-owned unit is inspected and functionally verified in-house before it ships and is backed by our pre-owned warranty.
