B&K PRECISION BK4007B 函数信号发生器, 直接数字合成器, 7MHZ
is a versatile DDS direct digital synthesis sweep function generators with high signal precision and stability. It generate sine and square waveforms up to 7 MHz or 12 MHz, including triangle/ramp waveforms up to 1 MHz. Both models provide variable output voltages from 0 to 10 Vpp into 50 ohms or up to 20 Vpp into open circuit. A continuously variable DC offset allows the output to be injected directly into circuits at the correct bias level.
