3MHz/6MHz Digital AC Millivoltmeter
SM2100 Series is a high-precision digital AC millivolt meter available in models SM2130 (3MHz) and SM2160 (6MHz). It is capable of measuring sine wave AC voltages within the range of 50µV to 400V for SM2130 and 50µV to 300V for SM2160, with corresponding frequency ranges of 5Hz to 3MHz (SM2130) and 5Hz to 6MHz (SM2160). The meter is equipped with dual independent channels, an LED display, and offers both auto and manual ranging options. It supports multi-unit display including V, dBV, dBm, Vpp, and dB, and comes with a standard USB interface (LAN is optional). Boasting high resolution, with SM2160 reaching up to 0.1µV in the 3mV range, along with reliable accuracy, it serves as a versatile tool for small signal measurement.
