1465 series signal generators, with the frequency range of 100kHz ~ 67GHz, are provided with high purity spectrum and high output power. The single side band phase noise at 10GHz carrier and 10kHz frequency offset is -126dBc/Hz. The maximum output power reaches up to 1W at 20GHz carrier, and the dynamic output power range gets 150dB. All these specifications can meet the high-end requirements of electromagnetic signal tests. In addition, 1465 signal generators own the functions of high-precision analog sweep and high-performance analog and pulse modulation, with maximum bandwidth of internally modulated signal generator up to 10MHz, various signal waveforms, the minimum pulse width of 20ns and flexible pulse trains, which can meet the test requirements of analog and pulse modulations. A 10.1-in. display screen of 1280×800 resolution as well as a number of independent operation styles, such as buttons, mouse and touch screens are equipped so as to improve user experience and test efficiency. 1465 signal generators can generate high-quality continuous-wave or modulated signals, which are not only ideal local oscillation source and clock source, but also high-performance analog simulation signal source. They are mainly used in the radar performance evaluation, high-performance receiver test and components parameter test etc., and applicable to communication and navigation equipment etc.
