AWG2300 USB Multifunction Arbitrary Waveform Generator

Product Functions

AWG2300 is an arbitrary waveform generator that supports two high-speed waveform generation channels, eight analog input channels, four analog output channels and eight digital IO channels, via a USB connection to the PC, all within a pocket size package ideal for instrumentation control and system integration applications.

Waveform generation

AWG2300 is a dual-channel (CH A and CH B), 14 bit, 300MS/s simultaneously sampling arbitrary waveform generator capable of generating waveforms from DC to 50MHz. The maximum output voltage is 7Vpp when driving 1M Ohm load, and 3.5Vpp when driving 50 Ohm load. When connected to a PC via a standard USB cable, the AWG appears as a virtual RS232 COM port that can accept data and instructions from the PC. Various waveform parameters including the frequency, amplitude, offset and phase of the output waveform are adjustable by the AWG control software running on the PC. The designed waveform data is downloaded to the AWG via the USB cable by the same control software. After being programmed, the AWG can run on a +5V DC power supply without the PC in stand-alone mode, or remain USB powered.

Analog Input

Eight multiplexed analog input channels (AI 0 - AI 7) with 10 bit A/D resolution are provided on AWG2300.  The analog input is running at the software controlled sampling rate transfering measured input voltage values to the PC.  The acceptable input voltage range is between 0V and 3.3V.

Digital IO

Eight digital IO (IO 0 - IO 7) channels are provided by AWG2300 and can be configured as input or output for each individual bit, or can be accessed as one byte.  The voltage level is CMOS (0V - 3.3V) compatible.  The digital IO update rate is controlled by software.

Analog Output

Four analog output channels (AO 0 - AO 3) generate analog control voltages from 0V to 4.096V, with update rate controlled by software.
