Test fixture · MB-EXP-0002

Ethernet / PoE Tap

Insert between an Ethernet power source and device to access receive-only network monitor ports and separate PoE voltage and current outputs.

To be announcedPricing

SKU MB-EXP-0002

Connections

LAN IN / LAN OUT
Place between the PSE or switch and the powered device.
Monitor ports
Connect compatible receive interfaces to observe the two monitored pair directions. Monitor outputs are labelled 10/100 only.
Voltage / current BNCs
Observe both PoE pair groups with suitable scope or voltage-meter inputs. Current observation outputs are voltage signals.

Required equipment

Network equipment

The Ethernet source and device under test, patch cables and compatible receive interfaces for packet capture.

Measurement instruments

Use one oscilloscope for the PoE power analyzer bench: one voltage channel minimum, or four channels for voltage and current on both pair groups. Voltage meters can read individual tap outputs separately.

Connections

Use compatible monitor interfaces and a common measurement reference. Power the fixture separately from its USB-C input.
