Waveform Generation Tutorial
HDG2000 Series Arbitrary Waveform Generator
50
The series signal generator can output kinds of standard Functions. For example: Sine wave,
square wave, ramp wave, pulse, noise wave, DC signal, sinc, exp fall, lorentz, gause, haver sine,
Dual Tone, ECG.
Frequncy
Frequency is the number of occurrences of a repeating event per unit time. It is also referred to as
temporal frequency, which emphasizes the contrast to spatial frequency and angular frequency.
The period is the duration of one cycle in a repeating event, so the period is the reciprocal of the
frequency. Units are μHz, mHz, Hz, KHz, MHz.
Period
Frequency is the number of occurrences of a repeating event per unit time. It is also referred to as
temporal frequency, which emphasizes the contrast to spatial frequency and angular frequency.
The period is the duration of one cycle in a repeating event, so the period is the reciprocal of the
frequency. Units are s, ms, μs, ns.
Amplitude
The amplitude of a periodic variable is a measure of its change over a single period. Units are Vpp,
mVpp, μVpp.
DC Offset
When describe a periodic function in the frequency domain, DC offset is the mean value of the
waveform.
High Level/ Low Level
The signal level value of the maximum value is signals of high level. The minimum value is low
level, units are V, mV, μV etc.
Phase
Unit is degree. The starting phase range can be set from 0 ° to 360 °. The default phase value of
0 °.
Duty
Duty is the pulse duration and pulse ratio of total cycle. Unit is %, the default value is 50%.
Symmetry
Symmetry is defined as a percentage of triangular wave rise time and period.
Symmetry range can be set from 0% to 100%. The default value is 50%.
