| Application Notes: Fluke 225C Color ScopeMeter® Data Sheet 190 Series Color ScopeMeter Test Tool with Industrial Bus Health Test
 | Industrial Bus Health Test verifies electrical signal quality on industrial buses including Profi®, Foundation™, Modbus®, CAN-bus, AS-i bus, RS-485 and more Easy signal validation of all relevant signal parameters Complete 190C Color ScopeMeter® (200 MHz or 100 MHz model) built in Floating and fully isolated inputs for true differential signal measurements | The Fluke 225C ScopeMeter® Test Tools are the instruments of choice for maintenance specialists who deal with industrial buses and networks as well as general electronics. You can verify the electrical integrity of your bus and network physical layer, performing tests and getting answers quickly and easily. Based on the 200 MHz or 100 MHz 190C Series Color ScopeMeter® digital storage oscilloscopes , these instruments offer all the functions found in the 190C Series, plus added measurement capabilities for industrial networks such as Profi®, Foundation™, Modbus®, CAN-bus, AS-i bus, RS-485 and more. Bus Health Test Bus Health Test analyses the electrical signals on the industrial bus or network and gives a clear "Good", "Weak" or "Bad" validation mark for each of the relevant parameters, presented next to the actual measurement value. Measured values are compared to standard values based on the selected bus type, or you may set your personal reference values if you need different tolerances. The Fluke 225C 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 terminators. Floating independently isolated input channels Thanks to the independently isolated input channels and the floating inputs, the ScopeMeter can take floating differential measurements from balanced 2-wire systems such as RS-485 and CAN. 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.  Large color screen
The large color screen of the 225C shows the individual parameters with validation, the actual measured value, the minimum and maximum values recorded over time, and the reference values used for the validation. The choice of parameters differs with the bus type and may include bias voltage, signal high- and low-levels, rise- and fall-times, in-band and out-band noise levels, jitter, pulse width, baud rate, and more. Activity indicators The activity indicators tell you the data flow is ongoing and they stop flashing the moment communications come to a halt. Signal integrity analysis In the eye-pattern 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. Fluke 225C 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 (see full line ScopeMeter® Test Tools brochure) supports industrial network verification using a common reference ("ground") connection, and includes a 40 MHz Industrial ScopeMeter®.
