New range of intelligent probes

August 2003 Maintenance, Test & Measurement, Calibration Integrated Solutions

Spescom MeasureGraph has announced a range of Intelliprobes for the Ultima and Accura families of digital and transient storage oscilloscopes, developed by Gould Nicolet Technologies.

The range includes differential voltage and current models. They all integrate fully with power and control, making a complete intelligent measurement system from probe tip to analysis and reporting. Range, coupling and offset are fully controlled from the main instrument as well as the automatic zero offset calibration maintaining overall accuracy. The probes are all high impedance and remove circuit loading providing safe operation when making off-ground measurements.

For high frequency analog and logic design, the 400 MHz model with up to ±40 V of input signal offset provides high sensitivity for off-ground signals. The 100 MHz model caters for switching signals while rejecting common mode voltages up to ±1400 V. The 25 MHz models maintain the 0,25% instrument accuracy. All models have high common mode voltage rejection. The current probe is a 100 A, DC-coupled model using Hall effect technology that operates up to a frequency of 100 kHz.

The Intelliprobes support the Ultima and Accura ranges of instruments making full use their performance in speed and accuracy. The Ultima 500 provides four measurement channels with the capability of achieving sampling speeds of 2 Gsps to 1 MB of memory. The Accura range also offers four channels with 0,25% accuracy and sampling speeds up to 100 Msps to 4 MB memory at 12-bit resolution. (At lower frequencies the resolution is increased to 16 bits.)
