General-purpose data loggers feature USB interface

Pico Technology has announced two competitively priced, multi-channel USB-powered data loggers. With resolution up to 12 bits and sampling rates up to 1 MS/s, the PicoLog 1000 series of multi-channel voltage data loggers offer excellent price/performance. In addition, the units provide up to four software-configurable digital output lines and one PWM control output, as well as a current-limited sensor excitation output, all in a compact, portable unit that plugs into the USB port of a standard Windows-based PC with no need for an external power supply.

Designed to suit a wide range of general-purpose voltage, sensor and transducer logging applications, the PicoLog 1000 series data loggers feature independent software-configurable control outputs, an external terminal board to facilitate connections and custom front-end circuitry, and a choice of 10-bit or 12-bit input resolution. They include everything needed for immediate use, and the free, comprehensive PicoLog data logging software package includes an SDK for custom programming.

Both loggers feature three sampling modes to meet most data logging needs: real-time continuous, streaming, and block mode. Streaming mode allows channel voltage readings to be logged continuously at 1 kS/s on any number of channels, while real-time continuous mode provides averaged, time-accurate readings with automatic measurements available in PicoLog. Block mode captures at the full 1 MS/s sample rate of the logger for the duration of the 8k sample buffer.
