Signal Generator
9kHz~3GHz/6GHz/12GHz/20GHz/40GHzCeyear Technologies Co., Ltd1Overview
Based on innovative technologies, the 1435 series signal generator achieves balance in terms ofperformance, economy and volumetric weight. It also has excellent spectral purity, with a single sideband (SSB) phase noise of -136dBc/Hz (when the carrier is 1GHz and the frequency offset is 10kHz) or-116dBc/Hz (when the carrier is 10GHz and the frequency offset is 10kHz). It provides a high power
output and a large dynamic range, with the maximum output power up to 20dBm@20GHz and an output
power dynamic range greater than 150dB. It responds fast and switches to another frequency in only
1ms, which shortens the test time and improves test efficiency, meeting the needs of massive data
testing; in addition, it also has excellent analog modulation and pulse modulation functions. By adopting
advanced frequency synthesis and RF channel signal processing technologies, it can achieve highperformance while reducing the cost. Besides, it is equipped with a 7-inch high-sensitivity LED touch
screen, and supports operation by touch screen, panel buttons, rotary knobs, external mouse andkeyboard, etc., which fully upgrades the users’ operation experience. It adopts portable 3U chassis
structure and is featured by small size and light weight, and thus is easy to carry. The 1435 series signal
generator can meet both the test requirements for high performance in the R&D phase and the test
requirements for high efficiency in the production phase.

Multi-function function generator
The multi-function function generator consists of seven waveform generators for generating AM/FM/ΦM
modulated signals and low-frequency output signals. Two waveform generators can generate adual-tone modulated signal by internal addition and are used for AM/FM/ΦM. The seven waveformgenerators include two standard function generators, one double-function generator, one scan function
generator, two noise generators, and one DC generator. The DC generator generates DC levels, which
can only be used for low frequency output. For the waveform generator, its sine wave frequency range is
0.1Hz~10MHz, and its frequency range of triangle wave, square wave, sawtooth wave and pulse is
0.1Hz~1MHz, and the frequency resolution is 0.1Hz.
