关于产品

The NF WF194x Series Multifunction Generators have been evolving along with the customers’ desires. The WF194x Series are new additions to WAVE FACTORY product lineup. WAVE FACTORY products boast accurate and stable output, an abundance of output waveforms, various oscillation modes for various purposes, outstanding user-friendliness and the flexible generation of waveforms that engineers need. NF considers oscillators that offer the flexible generation of waveforms as the standard and continue to offer function generators with ever more advanced functions.  The NF WF1947 and WF1948 Multifunction Generators will be your choices.

产品特点

  • Display screen: 5” Color TFT LCD display
  • Low noise
    • The noise level is reduced to roughly one-tenth of those of previous models at comparatively high voltage output (about 2Vp-p/50Ω, without DC superposition) and within frequencies of up to 300kHz. By employing an attenuator, the noise level at the low voltage output of about 1Vp-p or lower has been reduced to between a half and one-third those of previous models. In all of the output ranges, dramatic noise reduction has been realized, which makes this product perfect for a wide range of uses
  • Low distortion
    • A complete revision of the circuitry has realized the generation of low-distortion sine waves with total harmonic distortion of 0.04% or less. In addition to the 16-bit resolution of waveform amplitude, high-quality sine waves are produced (Frequency Setting Range: 20Hz to 20k Hz, Amplitude: 0.25Vp-p/50Ω or greater)
  • Waveform amplitude resolution: 16-bit
    • The circuit structure we developed has realized a 16-bit resolution of waveform amplitude, which is the highest of any oscillator designed for a maximum frequency of 30MHz. High-quality 16-bit resolution of waveform amplitude is provided for all the waveforms you might need, including sine, square and arbitrary waveforms
  • Floating
    • Each output terminal is insulated from the housing, which makes it possible to connect the terminal to equipment with dissimilar electric potentials. The inclusion of floating output terminals reduces noise caused by ground loops
  • High amplitude setting accuracy
    • The auto range function facilitates the optimum selection of output voltage range, according to the amplitude and DC offset (including high/low level settings) settings. Further, by reducing the deterioration of the amplitude setting accuracy due to the setting level, it is possible to obtain a very high amplitude setting accuracy
  • Low fan noise
    • The rotational frequency (or revolution per minute) of the fan is controlled according to the detected ambient temperature
  • Versatile interfaces: GPIB and USB are provided as standard
  • Arbitrary Waveform Editing Software is provided as standard

产品功能

  • Wide array of output waveforms
    • Output waveforms including Sine, Square, Pulse, Ramp, Arbitrary Waveforms, Noise and DC are generated. The WF194x Series are possible to generate arbitrary waveforms of up to 512k words and up to 128 waveforms can be stored in the 4M-word memory. All the generated waveforms have 16-bit high resolution. High-quality waveforms are indispensable for improvement in the repeatability (or re-productivity) of tests. Arbitrary waveforms can be set on the main unit and the provided arbitrary waveform creation software “Arbitrary Wave Editor” makes waveform editing smoothly (See photo section)
  • Various oscillation modes
    • Sweep and modulation functions
      • It is possible to perform sweeps not only of frequencies, but also of amplitudes, phases, offsets and duties (0% to 100%). In sweeping, it is possible to combine one-way or shuttle, linear or logarithmic slope (Logarithmic mode is supported only for frequency sweeping), and continuous, single-shot or gated single-shot modes. FM, FSK, PM, PSK, AM and DC offset modulations and PWM mode are supported. Internal and external modulations are possible (See photo section)
    • Burst / Trigger / Gate
      • In the burst oscillation mode, oscillation can be started or stopped at any wave count.WF194x Series support four modes, as to Auto Burst (No trigger is needed), Trigger Burst (Oscillation in sync with the trigger), Gate (Oscillation in sync with the gate signal) and Triggered Gate (Gate oscillation switched on/off by gate upon trigger). The phase where oscillation starts/stops and the level at which oscillation starts/stops can be set (See photo section)
  • As a pulse generator
    • You can use this waveform generator as a signal source for digital circuits or a pulse generator. The duty/time and the rising time/falling time of pulse waves can be individually set. The generator is suited to the operation testing of a wide variety of digital equipment and devices, data transmission equipment and more (See photo section)
  • 2-channel ganged operation (WF1948)
    • The dual-channel WF1948 offers channel modes of two phases, constant frequency difference, constant frequency ratio and differential outputs. Various types of sweeps are possible with the two channels in ganged operation mode. Each channel has a floating output terminal (See photo section)
    • Independent output (Indep): Two channels programmed separately
    • Two-phase (2-phase): Same frequency
    • Constant frequency difference (2-Tone): Difference in frequencies is constant
    • Constant frequency ratio (Ratio): Ratio of frequencies is constant
    • Differential output (Diff): Reverse phase waveform with identical frequency, amplitude and DC offset
  • External 10MHz frequency reference input, frequency reference output, synchronous operation of multiple ge6nerators
    • A high-accuracy frequency can be output when an external 10 MHz standard signal is input into the external 10 MHz frequency reference input (REF IN)
  • Synchronous operation of multiple units
    • Up to 6 units can be connected in the form of master/slave connections, using the frequency reference output (REF OUT) and external 10MHz frequency reference input (REF IN)
  • External additional input
    • This adds external signals to the waveform output signal
  • User-defined unit
    • The value in any unit can be set using a specified conversion expression (Frequency, period, amplitude, DC offset, phase, and duty)
  • Waveform monitor
    • This displays the set waveform
  • Memory to save setting
    • 10 settings can be saved
