General Safety Summary
Please understand the following safety precautions to avoid injuries and
damages to the product or any equipment connected. To be away from possible
dangers, please be sure to follow the regulations.
Only qualified persons are allowed to do the maintenance.
Prevent from fire and any personal damage.
Use Proper Power Cord. Use the power cord authorized in your country
only.
Correctly Plug in and Pull out. When the probes or the test leads are
connecting to the voltage source, please do not plug in or pull out.
Ground the product. This product is grounded through the grounding
conductor of the power cord. To avoid electric shocks, the grounding
conductors must be grounded properly before making connections to the
input or output terminals of the instrument.
Correctly connect probe. The probes’ ground terminals are at the same
voltage level of the product ground. Do not connect the ground terminals to a
high voltage.
Check the ratings of all terminals. To avoid fire or shock hazard, check all
ratings and marks on the product. Follow the user’s guide for detailed rating
information before making connections to the product.
Do not operate the product when the case or panel is removed.
Avoid Circuit Exposure. Do not touch exposed connections and

Introduction
DDS-3X25 Arbitrary Waveform Generator has one channel of arbitrary waveform
output, 12 Bits outputs, synchronized signal output, 1 channel of
Counter/Frequency Measurement input, 6 Bits inputs and external trigger input.
User can edit the waveform arbitrarily by the mouse or choose the regular
waveforms such as Sine, Square, Tri-angle, Saw-tooth, TTL, White Noise, Gauss
Noise, Trapezia, Exponent, AM and FM. The parameters, such as amplitude,
frequency and offset, are also settable. The data format of DDS-3X25 is
completely compatible with that of Tektronix; it can directly read the waveform
data files produced by the Tektronix oscilloscope or Tektronix waveform editor
software and redisplay the waveform. DDS-3X25 adopts the DDS technology so
that it has the advantages of high frequency accuracy, high waveform resolution,
high reliability, and wide software support. It can be widely used in various kinds
of electronics labs and it offers complete interface for second time development
to be pointlessly inserted into other auto-measuring systems.
