11H01 - Fluke 225C ScopeMeter Handheld Oscilloscope

Fluke 225C – Color ScopeMeter with Industrial Bus Health Test capability

Based on the 199C and 196C Color ScopeMeters, the 225C offers 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.

Features

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.

Automatic analysis and validation of electrical signal parameters

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.

All common bus types are supported and accessible through a simple menu structure

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.

BHT190 Break-out adapter with DB-9 connectors gives access to all individual wires and pins of the connection system.

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 super?uous 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 scope’s 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, two-wire systems including Ethernet 100Base-T.

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 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 40 MHz Industrial ScopeMeter. The 225C gives more extensive industrial bus signal analysis capabilities. Thanks to the isolated channel structure, the 225C gives a far better immunity to common mode noise and disturbances and can measure common mode voltages separately. On top, the 225C comes with higher measurement speeds and gives you all the measurement capabilities associated with the 190C Series.
