Improved isolated high voltage four-channel 200MHz oscilloscope

Saelig Company Inc now offers the Cleverscope CS548 Oscilloscope, a 2kV DC isolated channel oscilloscope intended to be employed wherever isolation and high CMRR are required. It improves on the past successful CS448 for power electronics and high-side test measurements. The device is an individually isolated channel high CMRR oscilloscope with four channels developed for measurements in situations, including an operating full or three-phase power electronic switching bridge on the low and high sides. It takes 14-bit measurements with isolated channel 2kV DC Class III capture and 100dB CMRR at 50MHz. The instrument provides frequency response analysis utilising an internal isolated signal generator, component LCR measurement, multiple-hour streaming to disk at >2MSa/s, high-resolution spectrum displays, sophisticated math, with Matlab and Excel live compatibility plus mixed signal features. The optional remote isolated digitiser CS1200 IsoPod connects to the CS548 by fibre link at up to 30yds for usage in high voltage enclosures to offer 30kV isolation.

The device may be employed to make measurements of all high-side nodes, do EMC measurements, check out start-up behaviour, calculate power loss and switching energy, and study message contents. Employ it for stability analysis and gain/phase on working power electronics modules, impedance measurement of power planes, inputs and outputs, and measurement of inductors and capacitors over frequency. Application examples comprise gate drives to measure voltage and charge, the power switch to measure loss and parasitic stress, the output to measure power and spectrum for EMC compliance, and the control system for Gain/Phase and stability. It can be employed to make measurements of all high-side nodes, do EMC measurements, check out start-up behaviour, calculate power loss and switching energy, and examine message contents.
