Introduction
This operation manual is used for all models of this series of DDS function generator. The last two digits in the
model number represent the maximum frequency of the channel A. There are four models to choose from this
series, with max.frequency range of 10MHz, 20MHz, 40MHz and 60MHz.
This series of DDS function generator uses Direct Digital Synthesis (DDS) technology. Its outstanding
performance and system features make this function generator a perfect solution for your testing requirement. The
simplified and optimized design of the front panel and dual-language (English/Chinese) TFT display interface
make your testing much easier for operation and observation. Additionally, the extendable optional functions can
also improve your system characteristics.
Technical characteristics and system features:
z High-accurate Frequency: up to the 10
-5
order of magnitude
z High Frequency Resolution: full-range resolution is 40 mHz (extendable to 40µHz)
z No Range Limitation: no frequency level switch, frequency set directly by digit keypad
z No Frequency Transition: momentarily switch to the stable value on phase and amplitude without
transition and distortion
z Precise Output Waveform: output waveform is synthesized by the preset function calculation values,
very accurate and less distortion
z Multiple Waveforms: output 32 kinds of the pre-stored waveforms
z Pulse Characteristics: set accurate pulse duty cycle
z Harmonic Wave Characteristics: output the fundamental and harmonic waves with adjustable phase
z Sweep Characteristics: frequency sweep and amplitude sweep, free to set the start and stop points
z Modulation Characteristics: output FM and AM signals
z Shift Keying Characteristics: output FSK, ASK, and PSK signals
z Burst Characteristics: output pulse waveform with burst count
z Store Characteristics: store 40 sets of the user parameters and recall
z Counter Characteristics: count the frequency, period, amplitude RMS value or peak-to-peak value
z Operation Mode: key operation for all functions, English/Chinese menu selectable, parameters settings
by numeric keypad or rotary dial
z High Reliability: use VLSI components and surface mount technology
z Protection: over voltage protection, over current protection, output short circuit protection, reverse
voltage protection
z Frequency Testing: optional frequency counter, capable of external frequency signal testing
z Power Amplifier: optional part, maximum output power up to 7W
z Remote Control: optional USB and RS232 interface
