hp8921a综合测试仪（Hp8921a comprehensive tester） Comprehensive tester In addition to HP8921A test simulation of AMPS and TACS base station, but also for you to measure digital cellular system required to upgrade to include: * TDMA * CDMA * CDPD High performance spectrum analyzer HP8921A spectrum analyzer has a wide dynamic range and high precision of frequency synthesis, these characteristics before only expensive spectrum analyzer to be independent. Wide dynamic range HP8921A can locate the low level signal in high power transmitter environment. High precision frequency synthesis said correction signal you locate has a high degree of confidence. The frequency range from 1GHz spacing is 5kHz to narrow, HP 8921A can easily display the entire spectrum of RF, also can zoom in and out of the specified signal. Mark function can display any signal frequency The built-in tracking generator HP8921A spectrum analyzer also includes a built-in tracking generator used to tune the base station duplexer. +13dBm power output tracking generator as analog input diplexer. Spectrum analysis The instrument calibration level to ensure the accurate regulation of duplexer. The sign of the spectrum analyzer function, in the filter response any measurable diplexer suppression system. The antenna echo loss can be tracked by the HP8921A generator quickly accurate measurement. By tracking generator, through an external antenna of SWR bridge drive, can measure the reflected power HP8921A. By tracking generator can realize other test The amount of filter, cable or attenuator insertion loss and frequency response. The output level of the tracking generator from -137 to +7dBm with IF to RF transform with variable frequency offset measurement. Spectrum The analyzer calibration range for each case 1, 2 and 10dB, and have normalization and mark function, therefore, the HP8921A tracking generator suitable for all types of measurement and adjustment. Automatic station maintenance For the maintenance of compl
