The four input channels are completely isolated from each other for floating differential measurements, a key aspect for troubleshooting three-phase electronic devices such as variable frequency drives. The Fluke ScopeMeter chassis is isolated from the environment, with no cooling slots or fans exposing the instrument. It is IP-51 rated for dust and splash resistance, making it rugged enough for safe use in factories and installations. Its fast sampling rate of up to 2.5 GS/s and 400 picosecond resolution help users capture electrical noise and other disturbances to accurately diagnose the problem. With 100 MHz and 200 MHz models, these oscilloscopes offer the bandwidth needed to meet current and future needs. With four channels, users can simultaneously inspect input signals, output signals, control loops, or safety interlocks to troubleshoot issues such as:

 

 

- Signal amplitude or shape variations, noise, or disturbances induced through critical circuit nodes.
- Signal synchronization and timing problems.
- Attenuation, jitter, or drift as a result of impedance problems or environmental impacts.

The four channels are essential for testing variable frequency drives and electronic power inverters used in sustainable energy generation and transportation applications. Users can:
- View and measure harmonics, transients, and loads in three-phase electrical systems.
- Troubleshoot DC-to-AC converters by identifying faults in insulated-gate bipolar transistors (IGBTs) and control circuits.
- View and measure pulse-width modulation (PWM) waveforms and check for reflections and transients.

These new tools are comfortable and easy to use. With new high-performance lithium-ion batteries, the Series II ScopeMeters operate for up to seven hours. The external charger and easily accessible battery compartment cover allow for convenient battery changes and extended operating time. Two USB ports, electrically isolated from the measurement input circuitry, enable waveform capture and sharing. Users can easily store data on a USB memory device or connect the oscilloscope to a PC via the USB port and transfer waveforms or images for data analysis or archiving.
