The Tektronix TPS2000 series of power analysis oscilloscopes, available from TTid, has been updated to improve the viewability of the screen in field-based applications. The new TPS2000B series incorporates a brighter and higher-contrast screen which strongly improves the viewing experience in difficult lighting conditions or when viewing the screen from an acute angle, as can occur when working away from the bench. The TPS2000B differs from conventional oscilloscopes in having four fully isolated channels, making it uniquely suitable for measurements on multi-phase power installations. Using P5120 passive high-voltage probes, floating and differential measurements up to 600 V RMS Cat II can be made. As well as mains operation, the oscilloscopes can be operated from their built-in "hot swappable" batteries, which provide up to 8 hours continuous operation, making them ideally suited to field-based measurements. Standard FFT analysis can be used to reveal signal interference, crosstalk and other effects visible only in the frequency domain. Optional power analysis software provides harmonics analysis, instantaneous power waveform analysis, switching loss, phase angles, and dv/dt and di/dt cursors. The TPS2000B series is available in three versions with bandwidths up to 200 MHz and real-time sampling rates up to 2 GS/s. Prices start at £2120 (plus VAT), and TTid keep models in stock for immediate delivery. www.ttid.co.uk
