Australia’s electronics magazine siliconchip.com.au Stand B27 siliconchip.com.au Australia’s electronics magazine September 2018  49 Come and see Cleverscope’s VERY clever “scope” – CS448 – at ElectroneX Cleverscope will be demonstrating their CS448 fourchannel PC-based isolated oscilloscope at ElectroneX 2018 in Sydney. The design work for this new product took more than five years. The result is a scope with outstanding performance. It’s designed for challenging applications such as probing high-voltage, high-frequency variable speed drives which involve very fast common mode voltage rise and fall rates. This sort of application requires a scope with multiple isolated channels, wide bandwidth, high precision and low capacitance. The high precision is especially important for accurately measuring current flowing through very low value shunts in high-power devices. The CS448 uses 14-bit analog-to-digital converters (ADCs) with very low noise, which give a resolution of 0.1V on the 800V range. Its high precision means an error of less than 1% when measuring current in a sense resistor with a common mode voltage slewing 680V in 10ns. Channel capacitance is under 10pF to minimise common-mode capacitive current when probing highvoltage switching systems. The CS448 uses high-bandwidth digital fibre-optic isolators to provide 1000V isolation between channels, and between each channel and the controlling PC. It also uses a carefully crafted isolated power supply and shielded digital circuitry, to keep noise injection into the scope front end to a bare minimum. The common-mode rejection ratio (CMRR) exceeds 100dB up to 65MHz; an outstanding result. That means less than 2mV of common-mode signal injection for a common mode voltage swing of 680V in 10ns! That’s for a 1:1 probe; it’s still a modest 20mV when using a 10:1 probe. The CS448 also incorporates a low-jitter clock system to keep measurements synchronised. This also allows multiple scopes to be synchronised, as a way to expand the number of available channels. Extremely low jitter in the clocks allows full advantage to be taken of the 14bit ADC resolution. Come see us and have a chat to the designer, Bart Schroder, at stand A13 at the ElectroneX show. 50 Silicon Chip New Electrolube resins on display at the HK Wentworth Stand (A16) Electrolube, distributed in Australia by HK Wentworth, will showcase some specialist encapsulation resin systems and thermal management materials for Australia’s LED manufacturers at this year’s ElectroneX.
