  • High accuracy
    The WF1973 and WF1974 are high-specification instruments that deliver exceptional precision, stability and reliability in support of a wide variety of applications.
  • Frequency accuracy : ± (3 ppm of setting + 2 pHz)
    Frequency resolution : 0.01 µHz
    Amplitude accuracy : ± (1% of amplitude setting [Vp-p] + 2 mVp-p)/open
  • Phase setting resolution : 0.001° (setting range: –1800.000° to +1800.000°)
    Duty setting range : 0.0000% to 100.0000%; resolution: 0.0001%
  • Various Type of output waveforms
    Equipped with standard, arbitrary and “parameter-variable” waveforms.
    Output Waveforms: Sine, square, pulse, ramp, noise, DC, arbitrary and parameter-variable
  • The sequence function
    The sequence function programs can be programmed, so constantly changing signals—such as machine vibration and voltage fluctuation can be generated easily.
  • Floating
    Each output terminal is insulated from the housing, which makes it possible to connect the terminal to equipment with dissimilar electric potentials,reduces noise caused by ground loops.


  • Ultrasonic motor drive test, differential input / balanced input test, LCD panel operation test, digital circuit evaluation test, evaluation of various ICs
  • Simulation of gear rotation signal/Inverter evaluation/ABS・Power Steering Device Test/ECU・ sensor operation test
  • Echo canceller test, amplifier and speaker tone burst test / linearity measurement, wireless communication equipment evaluation test
