5MHZ 10MHz 20MHz DDS Signal Generator Dual Out


BRT MHS2300 Dual Channel DDS Signal Generator is a kind of high efficiency DDS signal source module with arbitrary waveform output and adjustable phase difference.  It is integrated with large-scale CMOS integrated circuits, high-speed 32-bit ARM microprocessor and surface mount technology, which improved the instrument’s immunity and longevity greatly. 2.4 inch TFT LCD screen with 320*240 resolutions was able to display all the parameters of the two channels and prompt the current key functions, avoid pressing buttons repeatedly. The instrument is widely applied in electronic engineering labs, production facilities, industrial site and researching institute, etc.



Adjustable Dual Channel DDS Signal Generator Features
– Adopting direct digital synthesis (DDS) technology, FPGA design, and ultra-low power consumption;
– With portable aluminum alloyed shell, sole DC 5V powered adapter, easy to carry;
– With a 2.4-inch TFT color LCD, variable function soft keys and a rotary encoder, greatly enhances the usability of the instrument;
– Perfectly symmetrical two channels can be synchronized to work, and the phase adjustable;
– Two or multi-machines can do multi-machines synchronous by TTL_IO port;
– Various basic function waveforms of sine, triangle, square, saw tooth, and pulse (duty adjustable);
– The minimum output signal frequency to 10uHz;
– With 100 sets (M00-M99) parameter storage locations, data of M00 is able to load as power on;
– With 15 sets arbitrary waveform storage locations for users self-defining, memory depth of each set is 1024*10 bits;
– Amplitude up to 20Vp-p as frequency ≦15MHz; amplitude up to 15Vp-p as frequency >15MHz;
– Minimum frequency resolution reaches 10μHz, minimum amplitude resolution to 10mV;
– With DC offset function (-100%~+100%);
– With FSK function, hop frequency, carrier frequency and FSK rate can be set freely;
– Three trigger modes, manual trigger, internal CH2 trigger, external trigger, an arbitrary burst of 1~1048575 can be outputted;
– If the setting is +100%, it can output any CMOS digital signal of 0~10V.
– Duty adjustment of pulse wave is accurate to 0.1%.
– The burst function can control the output pulses from 1 to 1048575.
– Frequency sweep, amplitude sweep and duty sweep with an arbitrary start and end point.
– With functions of frequency measurement, period measurement, positive and negative pulse width measurement, duty cycle measurement and counting.
– All parameters can be calibrated by internal program.
– Powerful communication functions and the completely open communication protocol, which makes it very simple to the secondary development.
– User can use PC to control the instrument and arbitrary waveform edited on the PC can be download to the instrument to output.
