NF WF1943B/WF1946B/WF1965/WF1966 Multifunction Signal Generator WF194xB/WF196x Series

●Adopts DDS (Direct Digital Synthesis), capable of generating high-accuracy, high-resolution, wide-band signals
WF 1943B/WF 1944B/WF 1945B/WF 1946B and WF1965/WF 1966 can output signals from 0.01μHz to 15MHz and 0.01μHz to 50MHz respectively. Using the fully synthesized method, the setting resolution across the entire frequency band is 0.01μHz, and the frequency accuracy is ±5ppm.
In addition, the WF 1956 also covers the high-frequency range of 100MHz.
Limited to CH2 (HF mode), PLL (phase-locked loop) method, sine wave continuous oscillation.

●Features the highest vertical resolution in this class of equipment, capable of outputting high-precision waveforms
WF 1945B and WF 1946B have 16-bit waveform resolution capability, achieving high-grade waveform and amplitude accuracy

●5 standard waveforms + arbitrary waveforms
Can output sine wave, square wave (50% duty cycle), square wave (variable duty cycle), triangle wave, sawtooth wave, inverse sawtooth wave, waveforms containing noise, and arbitrary waveforms. Arbitrary waveforms can be created through panel operation/via GPIB, USB interfaces, and up to 12 waveforms can be stored.
In addition, if the arbitrary waveform creation software 0105 Japanese version/English version is used, complex waveforms can be easily created and transferred on a personal computer.

●Sweep function and modulation function
Each parameter of frequency, phase, amplitude, offset, and duty cycle (limited to square wave) can be combined with continuous/single-shot/gated sweep/linear/logarithmic (logarithmic limited to frequency and amplitude) for sweeping.
In addition, various modulations such as AM, FM(FSK), phase(PSK), PWM, and offset can be performed
WF 1943B/WF 1944B are limited to FM(FSK) and phase(PSK)

●Burst/trigger/gate/trigger gate
The start and stop of oscillation can be controlled freely.
With the stop level function, the level when oscillation stops can be set arbitrarily.
The number of oscillation stop waves for burst can be independently set in units of 0.5 waves up to a maximum of 500000.0 waves

●Convenient square wave output settings
The duty cycle of the square wave is variable from 0% to 100%*.(Setting resolution is 0.0001%)
In addition, WF 1965/WF 1966 can set the rise/fall time of the square wave. (7ns～1ms)
The variable duty cycle range of the WF 1956 is 0.0100%～99.9900%

●2-channel operation (WF 1944B/WF 1946B/WF 1966/WF 1956)
Can output 2-channel independent/2-phase (variable phase)/constant frequency ratio/constant frequency difference/differential (for the same frequency, amplitude and offset are opposite waveforms)

●Reliable and smooth operation achieved with the keyboard prompt method
To make keyboard operation clear and easy to understand, WAVE FACTORY adopts the keyboard prompt method on the panel surface. Only the keys that can be operated in the next step light up in sequence, thereby always displaying the necessary and sufficient information

●User unit function
For frequency, period, phase, amplitude, offset, and duty cycle, arbitrary units can be set and displayed simply by inputting an arbitrary unit name and its conversion formula in advance.
There is no longer a need for cumbersome calculations each time a setting is made, and output signals conforming to arbitrary units can be obtained conveniently

●As a pulse signal generator
By combining functions such as variable rise/fall time (WF 1965/WF 1966), variable duty cycle, trigger oscillation, and trigger delay, it can be used as a pulse signal generator.
In addition to setting the pulse width/period, the high/low level values can also be set independently
