LeCroy debuts embedded-test tools
Rick Nelson, Chief Editor -- EDN, June 10, 2010
LeCroy recently introduced the ArbStudio AWGs (arbitrary-waveform generators) and LogicStudio 16 logic analyzer at the Embedded Systems Conference, which took place in April in San Jose, CA. The ArbStudio AWGs generate signals as fast as 125 MHz and include PWM (pulse-width-modulation) capabilities. The software interface that controls the hardware simplifies waveform creation with a navigation tree that allows easy access to all channels.
The ArbStudio series includes four models: two- and four-channel versions with analog-waveform capabilities plus two- and four-channel versions offering a combination of analog-waveform- and digital-pattern-generation capabilities. The four-channel models have an expansion port that allows you to connect as many as eight units. All models have a 125-MHz bandwidth, 1G-sample/sec maximum sample rate, 2M-point/channel memory, and 16-bit resolution. The instruments support both true arbitrary and DDS (direct-digital-synthesis) technologies. ArbStudio software runs on an external PC. The base price for ArbStudio ranges from $2490 to $4990.
The LogicStudio 16 brings logic-analyzer functions to a PC, providing 16 channels with a sample rate of 1G sample/sec and maximum input frequency as high as 100 MHz. LogicStudio 16 software provides a dynamic waveform display with an intuitive user
interface.
Tools for digital debugging include timing cursors, zooming and panning functions, a persistence display, and a history mode that can replay old data captures. LogicStudio supports protocol analysis for I2C (inter-integrated-circuit) interfaces, SPIs (serial-peripheral interfaces), and UART (universal asynchronous-receiver/transmitter) interfaces. It can trigger on bus addresses or data packets.
LogicStudio provides a communication link to LeCroy's WaveJet oscilloscope, thereby turning a PC into a mixed-signal debugging environment. The base price for LogicStudio 16 is $990.
