Fluke 120B Series Oscilloscope, 20MHz Bandwidth, 5.7 inch Screen Size - FLUKE-123B/EU

This oscilloscope is a handheld digital instrument designed for portable waveform capture and analysis in field and workshop environments. It uses a TFT colour display to present signals from two input channels and operates from an internal lithium‑ion battery, enabling untethered measurements where mains power is unavailable.

Features and Benefits:

• 20 MHz bandwidth delivers accurate low-frequency signal reproduction
• 17.5 ns rise time captures fast edge transitions
• 5 mV/div sensitivity resolves small amplitude signals
• 20 ns minimum time base enables fine time‑domain detail
• 500 ns/div maximum time base supports slower waveform observation
• USB, CAN, RS232 and RS485 interfaces allow diverse data connectivity

Applications

• Suitable for automotive CAN bus diagnostics and logging
• Ideal for on‑site industrial control signal verification
• Used for educational lab demonstrations of analogue signals
• Can be used for maintenance on low‑voltage electrical systems

How long will it operate between charges?

The internal lithium‑ion power pack provides approximately 7 hours of continuous operation.

Which safety voltage category is it rated for?

It is specified for use up to 600 V within CAT III and CAT IV safety classifications.

What connectivity options are available for remote data transfer?

Built‑in interfaces include USB alongside CAN, RS232, RS422 and RS485 ports.

How many channels can be measured simultaneously?

The instrument accepts two separate input channels for concurrent signal observation.

How does the weight of the device affect its usability?

At 1.4kg, it is lightweight and easy to carry, making it suitable for mobile use in diverse environments without causing user fatigue.
