The 4078C Series Arbitrary/Function Waveform Generators are dual-channel arbitrary waveform generators with 16-bit amplitude resolution. They provide variable output voltages from 0 to 10 Vp-p into 50 ohms, up to 20 Vp-p into an open circuit, and a continuously variable DC offset to bias the output signal at a desired level.

  • Generate waveforms up to 30 MHz (4078C) and 50 MHz (4079C)
  • 2 channels with dedicated output ON/OFF buttons for each channel
  • Up to 250 MSa/s sampling rate
  • Waveform length up to 4 Mpts/ch
  • Amplitude range of 0 to 10 Vpp into 50 Ω or up to 20 Vpp into an open circuit
  • 16-bit amplitude resolution
  • Linear and logarithmic sweep
  • Modulation techniques include: AM, FM, PM, BPSK and FSK
  • Adjustable duty cycle
  • Continuous, triggered, burst, and gate modes
  • Internal/external triggering and programmable markers
  • Variable DC offset ±5 V
  • Low jitter < 25 ps
  • NISPOM-compliant sanitization to securely restore factory settings
  • USB (USBTMC-compliant) and LAN interfaces standard
  • 4.3-inch LCD and Internal memory to store/recall instrument setups
  • Closed-case calibration
  • Overload protection of the outputs
  • cTUVus certification mark fulfils CSA and UL safety standards
