Product Overview
The YB2173/YB-2173 Dual-Channel AC Millivoltmeter is a high-performance electronic measuring instrument designed for laboratories, production lines, and scientific research. It simultaneously measures two independent AC signal voltages with advanced circuitry featuring high input impedance, low noise, and excellent frequency response. Compatible with sine, triangular, square waves, and other irregular waveforms, its dual independent channels support synchronous/asynchronous operation for comparative analysis. The sturdy desktop chassis with plastic front panel ensures both aesthetics and durability.
Key Features
Offering a broad measurement range of 30μV~300V and frequency coverage of 5Hz~2MHz (resolution down to 1μV), this millivoltmeter captures微小信号 with precision. Digital/analog displays (model-dependent) show true RMS values and dB/dBm readings, while overload alert flags enhance safety. The ground/floating input option adapts to varied reference potentials. Dual-range switches and isolated amplification circuits streamline multi-signal testing workflows.
Technical Highlights
Equipped with ultra-β low-noise transistors and shielded isolation technology, it minimizes interference for high accuracy in weak-signal measurements. Input impedance ≥10MΩ and capacitance ≤50pF reduce loading effects. Stable frequency response (±3% error within 20Hz~200kHz) and auto-ranging (smart models) optimize usability. Reliable operation is ensured with 220V/50Hz power supply and a 5-minute warm-up time.
Applications
Ideal for audio system calibration, telecom engineering, circuit R&D, and educational labs. Typical uses include stereo channel balancing, power supply ripple analysis, and filter characterization. Its compact design suits both mobile and benchtop applications.
