Product Description

Circuit Master 4000M

The Circuit Master 4000M Precision Active Oscilloscope is unlike any other oscilloscope as it provides some innovative test and measurement functions that enable engineers and technicians to perform several new types of circuit analysis. It is designed for safe probing of closely spaced components by adding precision DC measurement, signal storage and analysis functions to a traditional oscilloscope design. Indeed, a built in accurate voltmeter (24 bit) removes the need for multiple instruments, thus making the Circuit Master a complete test and measurement station.

In addition, the Active mode allows signals (AC and DC) to be injected into the board when required, allowing circuit conditions such as drive strength and source impedance to be checked - which is not possible with traditional oscilloscopes. In AC Active mode, the unit behaves much like a function generator. The Circuit Master even has a built-in Logic View 4 channel analyser for logic signal display along with the 2 analogue inputs. Firm Flex and VI Curve functions provide impedance signature analysis on powered and un-powered boards.
