Custom Slope Integrating A/D Converter
The M3500A features a proprietary slope integrating analogue-to-digital converter that delivers superior measurement stability and noise rejection. This advanced design filters environmental interference while maintaining excellent linearity across all measurement ranges.
Performance Advantage: At 6½ digits, the M3500A achieves 55 triggered readings per second via USB interface. For high-speed applications, 4½ digit mode delivers over 2000 readings per second into internal memory.
Data Acquisition and Connectivity
Beyond basic multimeter functions, the M3500A transforms into a comprehensive data acquisition system with optional 10 or 20-channel scanner cards. Temperature measurements support both RTD and thermocouple sensors with built-in cold junction compensation.
Mathematical Functions
Eight integrated mathematical operations enhance measurement capability: RATIO, %, Min/Max, NULL, Limits, mX+b, dB, and dBm. These functions eliminate the need for external calculations in many test scenarios.
PC Integration
TMC compliant USB 2.0 interface ensures compatibility with SCPI test programs, including direct emulation of Agilent 34401A commands. Included PC software provides:
- Real-time graphing and trend analysis
- Microsoft Excel and Word integration
- Data logging with 2000-reading internal memory
- Statistical analysis tools
Note: All accessories included: USB cable, test leads with safety probes, power cable, and comprehensive software suite.
