Product Functions

  • Key Navigation function
    • The WF1965 & WF1966 Series employ Key Navigation on the front panel to facilitate key operations as much as possible. Only the keys that are to be operated next illuminate sequentially and only necessary and sufficient information is displayed. With conventional oscillators, a single key used to have too many functions and displays as a result of pursuing many advanced functions. This made operations difficult. The WF1965-66 Series solve these problems, thereby supporting smooth and reliable operations (See photo section)
  • User unit function
    • Frequency, period, phase, amplitude, offset and duty can be set and displayed in desired unit if desired unit name and conversion formula have been input. Because you do not need to conduct complicated calculations each time you make settings, the output can be easily obtained in desired unit. This function enables values to be set in any engineering unit specified by the user (See photo section)
  • 2-channel mode (WF1966)
    • Various settings such as 2 independent channels, 2 phases (same frequency)/constant frequency ratio/constant frequency difference/ differential output (amplitude and offsets in inverted waveforms at same frequency) are available (See photo section)
      • Constant frequency ratio (Ratio) is a mode in which the frequency of 2 channels changes (is interlocked) so that the frequency ratio between 2 channels is constant. For example, this can be used as signal source for driving a device under test that uses gear mechanism
      • Constant frequency difference (2 Tone) is a mode in which the frequency of 2 channels changes (is interlocked) so that the frequency difference between 2 channels is constant. For example, this is convenient in simulating the relation of the target frequency and nearby noise in communication issue
      • Differential output (Diff) is a mode in which the one channel has amplitude and offset in the inverted waveform of those of the other channel at the same frequency. This can be used for testing differential output of amplifiers (See photo section)
  • Pulse generator
    • The WF196-66 Series can be used as a pulse generator by combining variable duty factor, trigger oscillation, and trigger delay functions. Settings can be made in the pulse width or period, in addition to independent level settings with high/low. This can be used in various digital devices, data transmission devices and device operation tests (See photo section)
  • Burst / Trigger / Gate / Triggered Gate
    • The WF1965-66 Series can control start/stop of the oscillation as you desire. With stop level function, you can set at which level the oscillation stops as you desire (resolution of 0.01%). In addition, the wave number to oscillate and stop can be set both independently by the 0.5 wave up to 500000.0 waves (See photo section)
  • Standard output waveforms
    • Standard waveforms such as sine, triangle, square, saw-tooth and inverted saw-tooth can be output (See photo section)
  • Sweep functions and modulation functions
    • Each parameter of frequency / phase / amplitude / offset / duty factor (square wave only) can be swept in combination of continuous / single / gated sweep and linear/log (log is available only for frequency and amplitude). Needless to say, sweeping can be set to pause or resume. Auxiliary input/output terminals for hold input, marker output, and X drive output are provided on the rear panel of the synthesizer. Modulation can be applied not only to AM, FM (FSK), phase (PSK), and PWM as a matter of course, but also to offset (See photo section)
  • Arbitrary waveforms
    • Up to 12 waveforms, with maximum length of 32kWords
      • 8kWwords: 12 waves
      • 16kWords: 6 waves
      • 32kWords: 3 waves
    • Complex arbitrary waveforms can be easily generated by using the bundled software, Arbitrary Waveform Editor 0105
    • Waveform generation functions: Standard waveform, function expressions, and linear and spline interpolations that specify control points (See photo section)
    • Waveform editing functions: Copy, cut, and paste, plus horizontal and vertical compression and expansion, four arithmetic operation
    • Transfer functions: Transfer waveform data, setting parameters, etc., viaUSB or GPIB interface
    • Display functions: Display or edit generated waveforms and digital patterns, and read markers
    • File operations: Save or load waveform data, setting parameters and waveform function expressions
  • Square wave output with universal setting
    • The square wave duty is variable between 0 to 100% with setting resolution of 0.0001%. With this, precise simulation of the duty-controlled mechanism that is used in in-vehicle ECU can be performed. Furthermore, the WF1965-66 Series can set rise/fall time of the square wave. The setting can be made in wide variable range of 7ns to 1ms with resolution of 3 digits. With this function, users can perform operation test on devices that use digital signal such as clock signal used in information equipment (See photo section)
  • External AM / External Addition
    • External amplitude modulation and external addition of waveforms are possible (See photo section)
