Eyepattern Mode
The Fluke 225C and 215C can make the signal quality validation as soon as electrical signals are passed along the network, without looking at the data content. They find errors like improper cable connections, bad contacts, incorrect grounding and missing or superfluous terminations.

In the eyepattern mode, a waveform display is built over successive signal passes to give you a visual indication of overall signal quality, noise levels and signal jitter, using the scope's user selectable persistence mode.

Floating Independently Isolated Input Channels
Thanks to the independently isolated input channels and the floating inputs, the ScopeMeter can take truly floating differential measurements from balanced 2-wire systems such as RS-485 and CAN, giving a high level of suppression for common mode disturbances and noise.

One input channel can be connected to measure the voltage between the two signal wires, and the other can be connected to measure the common mode voltage over ground at the same time, independently. This way, you may also measure the signals passing through the twisted wires of the 100Base-T Ethernet.

Fluke 225C and 215C
Compared with other ScopeMeters
All ScopeMeters allow you to perform the basic electrical tests (such as copper resistance and isolation tests) on an electrical system or a cable.

The Fluke 125 offers a cost-effective solution for making tests on industrial buses and networks, using a common reference ('ground') connection. The Fluke 125 also includes a fully featured 49MHz Industrial ScopeMeter.

The 225C and 215c give more extensive industrial bus signal analysis capabilities. Thanks to the isolated channel structure, the 225C and 215C give a far better immunity to common mode noise and disturbances and can measure common mode voltages separately.

On top, the 225C and 215C come with higher measurement speeds and give you all the measurement capabilities associated with the 190C Series.

Apart from the Bus Health Test functionality, the 225C and 215C incorporate the full functionality of the 199C and 196C Color ScopeMeters.
