Suplier Alat Telekomunikasi Beragam tipe yang memudahkan pekerjaan anda/perusahaan dengan harga yang sangat terjangkau dan kompetitif. Description : Brand New Price = $ 5999 BK Precision 2650A Handheld 3.3GHz Handheld Spectrum Analyzer * Installation, maintenance, and trouble shooting of wireless communication systems such as W-CDMA/CDMA, GSM, WLAN and Bluetooth * Detection of signal interference and undesired emissions * TV and broadcasting * Antenna alignment * Electric field strength measurement with dipole antennas (order M401-M406) * Magnetic field strength measurement with magnetic field probe (order PR 26M) * EMI compliance (E & H field measurements with optional accessories) * Large easy-to-read color display, 640 x 480 resolution * Convenient USB host port: save screen images and measurement results directly to a USB drive * DANL (displayed average noise level) of -127 dBm * Measurement functions: channel/adjacent channel power, occupied bandwidth, electric and magnetic field strength * Easy operation due to Auto Tuning * Fast sweep speed, minimum 10 ms, to help locate and identify elusive, transient interference signals B&K Precision’s 2650A is a compact, light weight and cost-effective spectrum analyzer for quick and precise signal investigations, especially away from the bench. At a weight of only 4 pounds (1.8 kg), the 2650A is by far the lightest full-featured spectrum analyzer available, yet it delivers performance and features comparable to a full-size bench spectrum analyzer and can operate up to 4 hours on a single battery. With its ease of use, measurement flexibility and unmatched portability, the 2650A spectrum analyzer is an indispensible tool for engineers and technicians who conduct field measurements in the 50 kHz to 3.3 GHz range.
