Why four channels?

High-power electronics are used increasingly to generate energy and conserve power consumption, especially in heavy-duty electro-mechanical applications. High-power inverters are used in solar and wind power equipment, while variable frequency drives help engineers conserve energy while precisely controlling electric motors for maximum efficiency. With the new Fluke 190 Series II ScopeMeter portable oscilloscopes, users can see more and fix more with four channels.

The new oscilloscopes’ fast sampling rate, up to 2.5 GS/s and 400 ps resolution, helps users capture electrical noise and other disturbances and diagnose exactly what is going on. With 100 MHz or 200 MHz models, the oscilloscopes deliver the bandwidth needed to cover both today’s needs - and tomorrow’s. With four channels, users can inspect input signals, output signals, feedback loops or safety interlocks simultaneously to solve problems like:

  • Signal variations, noise or disturbances across critical circuit pathways
  • Signal timing measurements and synchronization issues
  • Attenuation/input impedance mismatch
  • Signal fluctuation/drift

Four channels are indispensable in testing variable frequency motor drives and inverter power electronic technology used in wind energy and transportation applications. Users can test for:

  • Harmonics, transients and loads in three-phase power input
  • Troubleshoot dc to ac converters for faulty insulated-gate bipolar transistor (IGBT) gates or control circuits
  • Test pulse width modulation (PWM) output for reflections and transients

With four independent isolated channels, you can take on three-phase applications like industrial motors, variable speed drives, UPS, and inverters. By capturing and displaying input, output, and feedback loop signals simultaneously you can compare and contrast signal amplitude and timing relationships in automation control systems.

When you need four channels in a harsh, dirty, industrial environment, you need the Fluke 190 Series II oscilloscopes. They are the first four-channel scopes rated for CAT III 1000V/CAT IV 600 V environments.
