2 2 Working principle
2 2 1 Digital combination: To generate a voltage signal, traditional analog generator uses electron
components to constitute oscillator. While its disadvantages are low frequenc accurac and
stabilit , complex technolog , low resolution, not convenient for setting the frequenc and
programming b the computer. DDS is a digital wa of signal generating. It has no oscillator and
uses digit combination to generator a serial of data flow, and then generates an analog signal
through the D/A (digital analog converter).
For example, to generate a Sine, ou should firstl make Y=SinX digital quantification, and then
store X as address and Y as quantification data to waveform memor one b one. DDS uses phase
accumulation technolog to control the waveform memor ’s address. In each sampling clock
period, it accumulates the phase increment to the real time value of the phase accumulator.
Through changing phase increment to change DDS output frequenc value. According to the
address phase accumulator outputs, waveform memor gets out waveform’s quantification data,
and then converts to analog voltage through D/A and operational amplifier. Waveform data is
discontinuous sampling data, what DDS generator outputs is a staircase sine waveform. Higher
harmonic in the waveform has to be filtered b low pass filter (LPF), after that the outputs is
continuous sine wave.
2 2 2 Working principle: There is a high resolution digital analog converter(D/A) inside device,
which uses high accurac reference voltage source to provide reference voltage which can be set
for amplitude and offset control, thus we guarantee output amplitude’s and DC offset’s accurac
and stabilit .
After amplitude and offset controlling, the signals will go through attenuator, voltage amplifier
and power amplifier, and then be output b output interface.
Microcontroller (ADSP) controls ke board and displa ing, when the ke s are pressing, it will
recognize the code and then execute it. The displa circuit will displa instrument’s working status
and various parameters.
The knob in the front panel is used for changing the number in cursor position. Ever rotating to
an angle there will be a trigger pulse generating. Controller can judge whether it is left or right
rotating, if it is left rotating, the number in cursor position will be decreased one; if it is right
rotating, the number will increase one, and carr or borrow a bit continuousl .
