Fluke 120B Series Oscilloscope, 20MHz Bandwidth, 2 Channels - FLUKE-123B/EU/S


This oscilloscope is a handheld instrument for diagnosing and observing electrical signals in field and workshop environments. It offers a practical balance of frequency capability and portability, supporting both mains and battery operation and providing a USB Interface for data transfer and integration into test setups. The instrument is suitable for technicians who require on-site waveform capture and Basic signal analysis.

Features & Benefits


• 20MHz bandwidth enables accurate low-frequency signal inspection
• Two input channels allow simultaneous comparative measurements
• 17.5ns rise time captures fast transient edges
• 200V/div maximum vertical range accommodates high-voltage signals
• 5mV/div minimum sensitivity resolves small-amplitude waveforms
• 500ns/div maximum time base supports slower repetitive signals

**Applications**


• Suitable for commissioning and troubleshooting industrial automation signals
• Ideal for fault-finding on electronic control modules and sensors
• Used for verification of power-electronics switching transients
• Can be used for field validation of cable and connector integrity
• Used with portable test rigs where mains and battery operation are needed

How is the instrument powered during extended field use?


It accepts mains supply for bench work and runs from an internal battery for mobile diagnostics, allowing uninterrupted operation when mains are unavailable.

What interfaces are available for recording or analysing captured data?


A USB connection provides a direct link for transferring waveforms and interfacing with analysis software or storage devices.

What timebase range does it support for detailed timing measurements?


The device provides timebase settings down to 20ns/div for fine detail and up to 500ns/div for observing longer-duration repetitive signals.

Which approvals relate to safe use in professional environments?


It conforms to recognised IEC standards for electrical safety and measurement performance applicable to test instruments.

How Compact is the unit for use in constrained spaces?


The design focuses on a narrow profile to ease handling and access in tight panels and confined test locations.
