Dual Channel VI Curve Testing Conduct comprehensive circuit analysis with dualchannel signal input, enabling simultaneous component comparison and precise analog signature analysis without powering the boards. ASA Testing Solution Perform Analog Signature Analysis on all component types, including digital, analog, and mixed circuits. Features 4 adjustable frequency levels and 4 internal resistance settings for versatile troubleshooting. Practical Technical Specifications Display options: adjustable B channel positioning; choose A channel display or A+B channel display. 5V trigger signal output. Housing: compact ABS construction. Dimensions: 140 x 80 x 40 mm. Weight: 270 g. Advanced Measurement Mechanism Frequency range: 40 Hz to 14 kHz. Internal resistance adjustments: 56R to 20K. Interface: DC 5*2*1. Operation requires a userprovided power adapter: 24V 1A. Use scenarios Incircuit testing of unpowered boards: analyze components and compare responses without applying power, reducing risk and simplifying fault isolation during or verification. Troubleshooting digital, analog, and mixedsignal circuits: leverage ASA capabilities and multiple frequency and resistance settings to identify defective components or inconsistent signatures. Prototype development and design verification: use dualchannel VI curve analysis and A or A+B display options to validate component behavior and compare alternatives efficiently, with a compact, portable instrument.
