Product details
Model Number: AV4958
Brand Name: CETC EI
Key Specifications/Special Features:
Product overviewAV4958 multifunctional microwave analyzer integrates multiple functions like testingof cable and antenna VSWR, distance to fault (DTF), insertion loss and gain, spectrum analysis and power measurement, etc. It is flexible and convenient to carry. Battery is available for power supply so it is suitable for field testing. Used widely in several fields including field installation and tuning of electronic equipment in terms ofradar, communication and ECM, performance test, daily maintenance and emergent repair and test, the analyzer can help upgrade filed repair and support of users.Main Features1. Multiple measurement modes: Antenna feeder test: for test of cable and antenna (return loss, DTF,etc.)Network analysis: for test of full S-parameters (various display types);
Spectrum analysis: for spectrum analysis (field strength, channel power, occupied bandwidth, etc.);
Power monitoring: for power measurement;
Vector voltage measurement: for measurement of vector voltage;
USB power measurement: for power measurement of USB interface;
2. High performance
