20 MHz DDS Sweep Function Generator with Arb Function

Model BK4045B

3 Year Warranty

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.

  • Sine, square, triangle, and arbitrary waveform generation
  • Bright color LCD display with waveform preview
  • Linear and logarithmic sweep
  • AM/FM modulation
  • Adjustable duty cycle
  • Independent DC offset amplifier design allows large offsets on small amplitude (e.g. 10 mV) waveforms
  • Low-jitter square wave generation for simulating reliable clock signals, generating triggers, or validating serial data buses
  • Store and recall instrument settings
  • Output On/Off button
  • Internal/external triggering
  • Gate and burst mode
  • Built-in 50MHz counter
  • USB interface with SCPI-compliant command set
  • Short circuit and overvoltage protection on all inputs and outputs
