1.1 Features
The "
DF 1906 Digital Function Generator
" is a function gener ator based on a dir ect digital
synthes izer (DDS), which is small, light, and low-pr iced but features high accuracy and sophisticated
functionality.
・
Oscillation frequency
：
0.1 mHz to 2 MHz, setting resolution: 0.1 mHz. Frequency accuracy: ±25
ppm.
・
Even if the frequency is changed, the phase is continuous and the waveform is not cut off.
・
Maximum output voltage: 10 Vp-p/open, ±5 V/open. DC offset up to ±5 V/open can be
superimposed.
・
When the amplitude is changed, no unexpected voltage is generated. The waveform can be changed without
being cut off from 0 to the maximum amplitude.
・
In addition to the 4 standard waveforms : Sine wave, square wave, ramp wave, and DC, 4 arbitrary
waves can also be output.
・
The duty ratio can be changed for the square wave. The symmetry can be changed for the ramp wave.
・
Waveform data is set via a USB connection for arbitrary wavef orms.
・
A wealth of oscillation modes are available.
・
Continuous oscillation
・
Burst oscillation
・
Trigger oscillation
・
Gate oscillation
・
Main parameters can be read at a glance on a 40-digit x 2- line LCD display panel.
・
Almost all settings can be remote controlled via USB.
1.2 Applications
・
Measurement of filters, in particular of those with steep character istics.
・
Signal source of audio equipment and pulse motor us ing the burst oscillation mode
・
Signal source of an automated measur ement system
・
Oscillator for var ious experiments
