To Select Arbitrary Waveform
Press Arb, use
to open the 2/2 menu page, and then press Select Wform to
select “Builtin”, “Stored Wforms” or “Volatile Wform” for arbitrary waveform output.
Built-In Waveform
10 kinds of built-in arbitrary waveforms are provided by DG5000, including DC
(amplitude ranging from -10 V to 10 V), Sinc, Exponential Rise, Exponential Fall, ECG,
Gauss, Haversine, Lorentz, Pulse and Dual Tones.
Pulse
The Pulse mentioned here can be configured by setting the parameters “Width/Duty”,
“Leading” and “Trailing”.
 Width/Duty: the minimum Pulse Width is related to the current edge time,
ranging from 4 ns to “Pulse Period - 12 ns”, while Duty Cycle ranges from 0% to
100%.
 Leading: ranges from 2.5 ns to 1.9531 ks, and relates to the pulse period, pulse
width and the trailing edge.
 Trailing: ranges from 2.5 ns to 1.9531 ks, and relates to the pulse period, pulse
width and the leading edge.
Dual Tones
The Dual Tones signal can be used to measure the inter-modulation distortion
characteristic of non-linear devices (such as mixer or amplifier). Inter-Modulation
Distortion (IMD) will be generated when a non-linear device with multiple input
frequencies disturbs the adjacent channels or causes unexpected output at other
frequencies. DG5000 enables to generate such Dual Tones that the Inter-Modulation
Distortion from it can be measured by a Spectrum Analyzer. When measuring the
Inter-Modulation Distortion generated by the device under test (DUT), this signal can
be used as the measurement source.
