Mixed-signal circuit analyser

24 January 2007 Test & Measurement

The multifunction CircuitMaster 4000M from ABI Electronics is designed for use in all situations involving analysis and testing of circuits. The CircuitMaster is a unique circuit test instrument, designed with two aims in mind: to simplify the safe probing of fine pitch PCBs; to combine traditional and new test methods in one instrument

On fine pitch ICs and tiny components, probing component pins is difficult, and there is a constant risk of damage by shorting pins. With traditional instruments probing is 'blind' while instrument controls are adjusted. The CircuitMaster uses full automatic ranging to eliminate adjustments during probing, so the operator can continuously view the pin. In addition the CircuitMaster combines several types of instrument, further reducing probing operations without reducing measured information.

By combining active tests and passive measurements of AC, DC and frequency in one pass and then processing through the signal reasoning software (SRS), which applies thresholds and comparative criteria to signals measured. This gives a complete and accurate snapshot, with a comparison against expected thresholds for the component or circuit type.

The CircuitMaster has a 40 channel I/O for coverage of ICs and connectors. A much higher degree of understanding over normal passive measurements is achieved by utilising all the functions, making it invaluable in design, production, test and repair.

The CircuitMaster 4000M consists of: full colour wide viewing angle TFT LCD; two analog channels; four digital input channels; two pulse output channels; 40 channel clip testing connector; footswitch for operation; USB connection.
