The KH1656C digital synthesis signal generator is a high-precision, high-stability, high-resolution intelligent frequency synthesis signal generator, which also has the main functions of a precision function generator. The instrument adopts the latest DDS digital frequency synthesis technology to ensure that the output frequency has the stability of the crystal, the output frequency has the minimum resolution of 0.01Hz, and the conversion speed is extremely fast. All parameters preset operation, directly enter the required output frequency and level, the output level can be preset by mV, V, dBμV, the output attenuator resolution is 0.1dB minimum, the output impedance is 50Ω, the output frequency and amplitude are all LCD Liquid crystal digital display.
This manual describes the KH1656C digital DDS composite signal generator, highlighting its high‑precision frequency synthesis from 0.5 Hz to 20 MHz and multiple waveform outputs (sine, square, pulse, triangle). It details the front‑panel layout, LCD read‑outs, and the available IEEE‑488 (GPIB) interface for computer control.
The document also covers power requirements, environmental limits, dimensions, weight, and maintenance procedures, including recommended operating conditions and warranty information. This manual is written in Chinese.
