NF WF1946B - Features

1-2 WF1946B
1.1 Features
The WF1946B Wave Factory is a multifunctional synthesizer based on the direct digital synthesizer (DDS)
system.
Although the WF1946B is two-channel device, the series also includes a single-channel WF1945B, a
single-channel WF1943B with basic functions, and a two-channel WF1944B with basic functions.
z Frequency setting range : 0.01 µHz to 15 MHz
z Maximum output voltage : 20 Vp-p/open, ±10 V/open
z Waveform resolution: 16 bits
z Key navigation lights the next keys to be operated, thus improving operational ease.
z User units function allows setting formula and character string to convert settings and display to the
desired units.
z LOAD function aligns the setting and actual output voltages when an arbitrary load impedance in
connected.
z Convenient use as a pulse generator with pulse period, width, high level and low level setting and
display. A trigger delay function is also included.
z Five standard waveforms: sinewave, triangular wave, squarewave, rising sawtooth and descending
sawtooth, plus arbitrary waveform.
z Frequency change and frequency sweep are coupled with phase, avoiding waveform cutoff.
z Unpredicted voltage is not produced during amplitude change. Since the output range is fixed, the
amplitude can be changed from 0 to maximum without waveform cutoff.
z Versatile channel mode utilizing 2 channels
・2 channel independent mode
・2 phase mode oscillating at the same frequency
・2 tone mode oscillating at a fixed frequency difference
・Ratio mode oscillating continuously at a fixed frequency ratio
・Differential mode for simultaneous output of waveforms with top and bottom symmetrical
z Versatile oscillation modes
・Continuous
・Intermittent: Burst, trigger, gate, in addition to triggered gate for repeated oscillation start/stop
・Sweep: Sweep for not only frequency, but also phase, amplitude, DC offset and duty.
・Modulation: FM (FSK), phase (PSK), AM, DC offset and PWM
・White noise generator
・DC voltage generator
z Floating inputs and outputs to prevent ground loop effects. Isolation is also used between channels.
z The 1991 synchronous operation option enables synchronized operation of multiple units and operation
as an oscillator with increased number of channels.
z The 1992 digital output option can provide a 15 bit digital signal corresponding to the output
waveform and enable use as a digital pattern generator.
