Tektronix MDO32 3 Series Mixed Domain Oscilloscope

The Tektronix MDO32 3 Series Mixed Domain Oscilloscope integrates oscilloscope, spectrum analyzer, logic analyzer, and digital voltmeter functionality into a single portable platform. This instrument addresses embedded system design, power electronics, and complex signal analysis with 2 analog channels, selectable bandwidth up to 1 GHz, and an 11.6-inch HD capacitive touchscreen. The spectrum analyzer covers 9 kHz to 1 GHz standard (upgradable to 3 GHz) with dedicated RF input, while optional modules add 16-channel logic analysis, 50 MHz arbitrary waveform generation, and power quality measurements. FastAcq technology delivers waveform capture rates exceeding 280,000 wfms/s.
