Basic Operation

For the ITO and xDSL Throughput Tests, starting the test causes the following actions:

1.The local unit (ATU-R for xDSL) sends an ARP request to the remote unit (ATU-C for xDSL) specified in its Remote IP Address (Target ATU-C IP in xDSL) and waits for a response to that request.

2.After the ARP response is received, the local unit (ATU-R for xDSL) requests the remote unit (ATU-C for xDSL) to generate traffic using the local unit’s (ATU-R for xDSL) user-configured duration, data pattern, rate, and frame length. The local unit (ATU-R for xDSL) waits for the remote unit (ATU-C for xDSL) to acknowledge the receipt of the traffic generation request.

The number of frames per second for the upstream and downstream bit rates is also calculated and displayed. The Ethernet preamble and inter-frame gap are used in this calculation and the number of frames per second is rounded up.

3.After the remote unit (ATU-C for xDSL) acknowledges the receipt of the traffic generation request, both units zero their counters and setup for

tracking the number of packets received from the other unit. Then, both units generate the user- configured traffic for the specified duration. The traffic generated is IP level data-grams, which allows routing. Both units transmit traffic simultaneously.

4.After the user-configured duration, the local unit (ATU-R for xDSL) requests the remote unit (ATU-C for xDSL) to send the number of packets counted from the local unit (ATU-R for xDSL). Knowing the number of packets sent and received from the remote (ATU-C for xDSL) and itself, the local unit (ATU-R for xDSL) calculates and displays the results.

Conducting a Throughput Test

The Throughput Test is part of the Internetwork Throughput Option (ITO) or xDSL. The Throughput Test is a double-ended test of line or network bandwidth that requires two Network Assistants. After configuring each unit, you connect the remote and local units to your network in locations that allow you to test between the two units. Figure 7-2 shows the relationship between the local unit (ATU-R unit, for xDSL) and remote (A, B, C, or

D)units (ATU-C unit, for xDSL). Figure 7-3 shows the equivalent connections for xDSL.

The Series II boasts a range of measurement capabilities. With the ability to measure voltage, current, and resistance, as well as additional readings such as frequency, capacitance, and temperature, these multimeters deliver unparalleled versatility. Many models in the Series II also feature True RMS (Root Mean Square) measurement capabilities, enabling accurate readings of non-linear and distorted waveforms, which are increasingly common in modern electronics.

Another significant feature is the advanced display technology. The Series II multimeters often come with large, high-contrast LCDs that facilitate easy reading in various lighting conditions. Some models even offer graphical displays, enabling users to visualize trends in measurement data over time.

User-friendliness is also a hallmark of the Fluke Series II. With intuitive interfaces and simplified navigation, users can access advanced features quickly. Auto-ranging capabilities allow the meter to automatically select the appropriate range for the measurement, minimizing user errors and streamlining the testing process.

Fluke's commitment to safety is underscored by the design of the Series II, which includes features such as safety-rated test leads, protective rubber booting, and a high-voltage warning indicator for added peace of mind.

Moreover, the connectivity options within the Series II enable seamless data transfer to PCs and mobile devices, facilitating easier logging and analysis of measurement data. Many models support Bluetooth or USB connectivity, making it easier than ever to integrate multimeter readings into existing data collection and analysis workflows.

In conclusion, the Fluke Series II multimeters stand out for their durability, versatility, and user-centric features. Their combination of advanced measurement technology, rugged design, and safety functions makes them essential instruments for professionals who demand accuracy and reliability in their work. The commitment to innovation and excellence that Fluke exemplifies ensures that the Series II remains a trusted choice in the field of industrial measurement tools.
