Fluke 120B Series Oscilloscope, 20MHz Bandwidth, 17.5ns Rise Time - FLUKE-123B/UK/S

This oscilloscope is a portable, digital handheld instrument designed for on-site signal inspection and diagnostics. It provides colour waveform visualisation on a TFT display and operates from a rechargeable lithium‑ion power source, making it suited to field technicians and engineers who require mobility and clear signal representation in diverse environments.

Features and Benefits:

• 20MHz bandwidth enables accurate low-frequency signal capture
• 17.5ns rise time supports fast edge measurement capability
• 500V/div vertical range for high-voltage waveform analysis
• 5mV/div sensitivity allows detailed low-amplitude measurements
• RS232 interface facilitates data transfer to external systems
• CAT II and CAT III safety ratings protect against common site voltages

Applications

• Suitable for troubleshooting industrial control circuits
• Ideal for verifying mains-derived signalling and sensors
• Used with portable test kits for field maintenance tasks
• Can be used for educational labs requiring visual waveform study
• Appropriate for service engineers working on power electronics

What power arrangements enable extended field work?

It runs from an internal lithium‑ion battery so measurements can be taken without mains supply and recharged between uses.

How does the instrument meet electrical safety expectations?

It is rated to CAT II and CAT III voltages and conforms to EN 61010‑1 standards for safe measurement on specified circuits.

What connection options exist for logging waveform data?

Data export and remote control are available via an RS232 port to compatible recording or analysis equipment.

Which plug configuration is supplied for mains charging?

It is provided with a UK plug suitable for connection to local AC supplies.

Supplied with

Li-ion battery pack, charger/power adapter, shielded test leads (2) with ground leads, black test lead, red and blue hook clips, banana to BNC adapter, carry case,
FlukeView for Windows software, magnetic hanger, screen Protector
