4045B - 

Model 4045B is a versatile 20 MHz DDS sweep function generator with arbitrary waveform capabilities. The instrument generates sine and square waveforms up to 20 MHz, triangle/ramp waveforms up to 2 MHz, and arbitrary waveforms (12-bit, 50 MSa/s, 1k point) with high signal precision and stability. Providing variable output voltages from 0 to 10 Vpp into 50 ohms (up to 20 Vpp into open circuit), the 4045B also offers linear and logarithmic sweep, AM/FM modulation, and a continuously variable DC offset to inject signals directly into circuits at the correct bias level.

Features:

Sine, square, triangle, and arbitrary waveform generation

Bright color LCD display with waveform preview
