RIGOL Technologies, Inc.

10 Standard Waves and DC Output:

Enable to output Sine, Square, Ramp, Pulse,
ExpRise, ExpFall, Sinc, Noise and DC waves.

Editable Arb Waves: Enable to edit and

output arbitrary wave up to 14bits and 4kpts.
In addition, the instrument provides 4
nonvolatile memories for saving custom
arbitrary waves. According to Ultrawave, more
waves could be edited and saved, or perform
analysis for the waves that has already been
uploaded to it.

Abundant Modulation Functions:

Support AM, FM, PM, PWM and FSK, the
modulated waveforms are intuitively shown on
the screen.

Sweep: It can output in the form of linearity

or logarithm from the start frequency to the
stop frequency during the sweep time (1 ms ~
500 s) you specified. Sweeping can be
generated by Sine, Square, Ramp or Arbitrary
waveforms.

Burst: It can generate versatile waveforms in

burst, which can last specific times of
waveform cycle (N-Cycle Burst) or output
gating pluse if applied external gating signal.

In order to meet the most basic needs of
users, UltraWave provides 9 standard
waveforms. In addition, hand drawing, line
(point by point) drawing and arbitrary points
drawing are also offered to make it easier to
create complex waveforms and to edit multiple
waves simultaneously through the multi-file
management interface.

Either, UltraWave has following utilitarian
functions:
 Save the arbitrary wave that has been

created as the format of .txt (text
file), .csv (CSV file) and .rdf (arbitrary
waveform file).

 Read the wave files stored as the format

of .Wfm from DS series Digital
Oscilloscope.

 Print wavefroms.
 Download the waves have heen created to

the internal storage of DG10X2.

 Windows operation: enable to perform

math operations such as“＋”、“－”、“×” for
the waves in two windows.

 Absolute operation: enable to perform

absolute operation for the selected waves.

 Filter: enable to perform low pass filtering

or smoothing for the whole wave.
