Fluke 225C Color ScopeMeter with Industrial Bus Health Test Capability
Based on the 199C and 196C Color ScopeMeters, the 225C and 215C offer the full functionality of those instruments yet with the addition of powerful test capabilities for a wide variety of Industrial Bus systems. When in Bus health Test mode, these ScopeMeters automatically make an analysis of the electrical signals passing through the bus, and compare the parameters to standard values as described in the industry standards for that bus type. Alternatively, the user may select an Eyepattern display to visually check the overall signal quality.
Parameters are automatically qualified as good, weak or bad based on a comparison to the appropriate industrial standards or to user set reference values. Each of the measured parameters is presented with momentary value and with statistical minimum and maximum values measured over time. The reference values used are also displayed, to give the user an easier grip on the systems behaviour. Tested parameters include signal amplitudes, bias voltage, rise- and fall-times, jitter, distortion and noise levels (in-band noise as well as out-of-band noise) depending on the requirements of the associated industry standard.

Bandwith:
|
200 MHz

|
Bus Health Test:
|
Verifies the electrical parameters of industrial bus systems using automatic measurement and analysis functions. Next to that, an Eyepattern mode is provided for visual inspection of signal quality.

Parameter Classification:
|
Default values:
-
well within limits = good, gives green tick mark
-
within specified percentage of the limit values = weak, gives orange tickmark
-
beyond limit values = bad, gives red tickmark
Limits values, as a default, are based on industry standard for the selected bus type or may be set by the user. The tolerance band (percentage) taken into account for the classification weak may be altered by the user.

The Fluke 225C and 215C are the instruments of choice for maintenance specialists who deal with industrial buses and networks as well as with general electronics. You can verify the electrical integrity of your bus and network, performing physical layer tests and getting answers quickly and easily.
Based on the 200 MHz or 100 MHz 190C Series Color ScopeMeters, these instruments offer all functions found in the 190C Series, with Bus Health Test capabilities added on top.
|
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.
|
|
|
All common bus types are supported
The 225C and 215C ScopeMeters support not just one or two bus systems but all commonly seen industrial buses. From the lower speed AS-i and CAN to the higher speed Ethernet 100Base-T based systems are covered by a single instrument. A simple menu structure allows for selecting the main bus type and, where applicable, sub-types listed in a sub-menu for easy selection. Tested parameters and reference values are then set according the selection made.

|
Large color screen
The large color screen of the 225C and 215C 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-of-band noise levels, jitter, pulse width, baudrate, and more. The activity indicators tell you the data ow is ongoing and they stop ashing the moment communications come to a halt.
|
|
Making test connections
The large screen also gives wiring information for each of the supported bus types, giving the user guidance in making the test connections. A set of break-out adapters is included with the 225C and 215C to give access to each of the wires and pins of the commonly used connection systems M12, DB-9 and RJ-45.

|
|
On screen help information includes visual guidance on making the test connections. The independently isolated input channels of the 225C support truly differential measurements on bus systems.

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 nd errors like improper cable connections, bad contacts, incorrect grounding and missing or superuous terminators. 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, using the scopes user selectable persistence mode.

 Eyepattern mode allows for a visual check of signal quality |
|
Floating independently isolated input channels
Thanks to the independently isolated input channels and the oating inputs, the ScopeMeter can take truly oating 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.
|
 Isolated, floating channels give a high immunity to common mode noise and allow for direct measurements on balanced |
