Описание Product overview4945 Series Radio Communications Test Set, which is a multifunctional and portable model based on software radio architecture, integrates plentiful functions, like frequency-hopping signal generation and analysis, vector signal generation and demodulation analysis, analog modulation signal generation and demodulation analysis, audio signal generation and analysis, audio oscilloscope, automatic testing and so on. The tester is capable of major performance testes on transmit and receiving of radio communication equipment, measurement and analysis on feature parameters of RF, modulation, audio, and digit etc. Wide applications of the tester cover R&D, production, verification, maintenance and repair, and testing on radio communication equipment, including short-wave/ultra short-wave radio stations, data link systems, communication and surveillance satellites, radio relay equipment. Defence mobile carriers with radio communication terminals like communication vehicles, surveillance vehicles, vessels and ships, as well as external field tests can use this tester conveniently. Main characteristicsMultiple RF testing functions:sweep spectrum analysis, broadband and narrow band power measurement, frequency error measurement, RF signal source;Analog standard communication testing:AM, FM, SSB signal generation and demodulation analysis. Equipped with graphic display of demodulation audio, SINAD, SNR, distortion degree, modulation rate and other measurement functions. The built-in speaker outputs demodulation voice in real-time. Modulation signal generator and modulation source support external audio and microphone;Digital standard communication testing (option):10MHz bandwidth digital vector signal generation and analysis, bit error rate measurement, with real-time output interface of digital demodulation;Frequency-hopping testing (option):60MHz transient bandwidth frequency-hopping signal generation and analysis. Frequency-hopping analysis supports measurements types like waterfall chart and frequency-time. Single capture lasts 1.3s at the bandwidth of 60MHz and the time resolution is 10ns;Audio signal testing:audio signal generation and analysis, the max. audio input level reaches 30Vrms (high impedance), the max. audio output level reaches 7Vrms (high impedance); capable of measurements on frequency, level, SINAD, SNR and distortion degree; audio generation supports dual-tone output; individual adjustment is available for dual-tone frequency and amplitude, phase is adjustable relatively;Dual-channel oscilloscope (option):DC~4MHz;Auto testing software:on-line editing of DUT (device under testing) parameters, auto pilot testing, yield of testing reports and other functions. The PTT control interface regulates transmit and receiving of DUT;Built-in attenuator with high power: the max. input power is as high as 150W; ;Portable structure: external dimensions (without handles): W426×H222×D180mm, easy for carry-on and application;Diversified power supply modes:the standard configuration supports AC220V or DC24V, built-in lithium battery is available;Support network interface programming control;10.4" large screen, resistor touch screen, English/Chinese interface, interface colors are free for your choice;Support simultaneous operations on multi-function windows, up to 4 windows can be operated at the same time.Technical specifications:
