Handheld test set checks IPTV over VDSL2
Exfo Electro-Optical Engineering has developed the first handheld test set to support IPTV and HDTV over a standards-based VDSL2 test module.
Exfo Electro-Optical Engineering has developed the first handheld test set to support Internet Protocol television (IPTV) and high-definition television (HDTV) over a standards-based, very high-speed digital subscriber loop, version 2 (VDSL2) test module. This new product announcement marks the latest in a series of test modules for the CoLT-450P, a handheld, battery-powered test set for installation and maintenance applications on copper-based broadband access networks. VDSL2 is beginning to be deployed by network service providers (NSPs) as a part of their strategy to offer standard definition (SD), high-definition (HD) IPTV and IP video-on-demand (VOD) services over multiple channels.
NSPs use a fibre-to-the-node (FTTN) configuration to bring VDSL-based digital subscriber line access multiplexers (DSLAMs) within 900-1200m of subscribers.
This architecture enables VDSL2-based DSLAMs to deliver up to 100Mbit/s of downstream data to each subscriber with typical rates of 30Mbit/s.
As such, VDSL2 is regarded as an economical and rapid deployment alternative to fibre-to-the-home (FTTH).
Exfo's CoLT-450P, equipped with a new VDSL2 test module, allows NSP installation and maintenance personnel to confirm upstream/downstream connection rates, signal levels, VDSL2 error statistics and other important parameters of the VDSL2 link-up.
Once a link is established, technicians can use the CoLT-450P to test the various protocol layers and the quality of the applications themselves.
Exfo's solution interoperates with VDSL2 equipment that is based on several different chipsets.
In addition, it is backwards-compatible with some interim VDSL 1.5 solutions that exist in the field.
The CoLT-450P is used to install and troubleshoot digital subscriber line (DSL) circuits that deliver triple-play services (voice, data and video) over high-speed access networks.
The CoLT-450P is the first DSL test set to be purpose-built for assessing the high bit-rate throughput of multiple-channel HDTV.
This easy-to-use, modular test solution acts as a golden modem for confirming the rates and other measured parameters provided by asymmetric digital subscriber line (ADSL), ADSL2, ADSL2+, reach-extended (RE) ADSL and now VDSL2.
As well, the CoLT-450P performs functional testing and quality-of-service testing for voice-over-Internet Protocol (VoIP) and Internet services.
The CoLT-450P is an indispensable tool for rapid installation and efficient troubleshooting of IPTV services.
It supports an industry-leading and flexible suite for IPTV test capabilities.
The CoLT-450P features high-performance video-packet processing speed and throughput.
Once equipped with a CoLT-450P, technicians can establish a DSL connection, log onto a service provider's network: 'join' and 'leave' various streaming video channels, and measure the quality of the video stream.
The CoLT-450P has the power to support the highest DSL rates and performance, while simultaneously handling multiple standard and high-definition video streams.
A 10/100BaseT Ethernet interface enables the CoLT-450P to operate as a complete home/office DSL modem and router, allowing it to work 'in-line' on a live IPTV service in conjunction with a set-top box.
'With NSPs poised to make large-scale deployments of IPTV services, the CoLT-450P is an indispensable tool for rapid installation and efficient troubleshooting', said Robert Fitts, Exfo's Vice-President of Product Management, Copper Access Group.
'Launching this new VDSL2 test module barely a few weeks after receiving the 2006 Frost and Sullivan xDSL Growth Strategy Leadership Award proves that Exfo means business in the DSL and triple-play test space and is highly committed to deliver the best IPTV test solution on the market'.

Measurement products for aerospace testing
At Aerospace Testing Expo, Rohde and Schwarz will showcase a cross-section of its broad portfolio of test and measurement products.
At Aerospace Testing Expo (Munich, Germany, 27th to 29th March 2007), Rohde and Schwarz (Hall A1, Stand 1204) will showcase a cross-section of its broad portfolio of test and measurement products, ranging from high-end instruments for signal generation and analysis to network analysis and standards-compliant EMC measurements. Depending on customer requirements, the company offers complete system solutions or stand-alone applications. Plus, individual products can be integrated into existing systems.
To ensure flexible use, the instruments from Rohde and Schwarz are downward-compatible.
And features such as LXI compatibility provide the safety of investment demanded by customers.
In everyday operation, antenna and radar systems must often handle pulsed signals.
Amplifiers and on-wafer measurements also require pulsed signals in order to avoid overheating.
With the R and S ZVA-K7 software option, Rohde and Schwarz has integrated pulsed measurements into the R and S ZVA family of high-end network analysers, thus providing a compact and cost-efficient solution.
Absolute levels, complex S-parameters, and quantities derived from them can be displayed in real time by using pulses with a resolution of 12.5ns.
The option makes it possible to analyse periodic and nonperiodic pulses as well as single pulses with an IF bandwidth of up to 30MHz.
Special advantages of the new method include simple test setup and adaptive error correction when measurement settings are changed.
When equipped with the R and S SMA-K25 option, the analogue R and S SMA100A high-end signal generator operates as a source for precise VOR/ILS signals.
The instrument's low modulation errors and high level accuracy permit reliable tests on air navigation receivers.
With a frequency range of 9kHz to 6GHz, it can be used for all applications in the lab, in production, and in service that require signals of high spectral purity.
The compact R and S SMA100A generates amplitude modulation (AM) and pulse modulation signals as standard.
For mil/aero applications, the instrument can be upgraded with a high-end pulse generator by means of the R and S SMA-K23 option.
To enable users to check and maintain ILS and VOR systems, Rohde and Schwarz has developed the R and S EVS300.
This robust level and modulation analyser with a weight of less than 6kg is ideal for use not only in the laboratory but also at airports and for performing flight inspections with measurement aircraft.
An internal calibration generator enables it to achieve very high level measurement accuracy.
In addition to extremely fast measurement value processing, the R and S EVS300 features an internal data memory that records up to ten million measurement data records for applications with maximum measurement speed or for long-term monitoring.
The measurement values can be transmitted over standard interfaces or copied to a USB memory stick.
In the absence of an AC supply, rechargeable batteries provide an operating time of 8-10h during continuous measurements.
Rohde and Schwarz will also present the R and S SMF100A at Aerospace Testing Expo.
This new analogue microwave signal generator claims new standards in single sideband (SSB) phase noise.
Thanks to its unique value of -115dBc (at 10GHz/10kHz offset), the instrument is ideal for a variety of telecommunications and radar applications.
In addition, high output power and very short setting times enable flexible applications in production.
With level and frequency setting times of 4 and 3ms, respectively, the R and S SMF100A achieves an outstanding value.
Moreover, the instrument provides output power of typically up to +26dBm without an external amplifier.
The R and S SMF100A is designed for a frequency range up to 22GHz.
To develop and produce high-quality transmit and receive equipment such as communications systems and radar, users need the conventional measurements of both a phase noise tester and a spectrum analyser.
The R and S FSUP is the only instrument worldwide that combines a spectrum analyser and a phase noise tester up to 50GHz.
With the R and S FSUP, Rohde and Schwarz for the first time offers an instrument specially designed for characterising RF signal sources and in particular for measuring phase noise.
The R and S FSUP incorporates the company's many years of experience in developing high-quality spectrum analysers and low-noise oscillators and synthesisers.
The R and S FSUP allows extremely flexible and easy test setups and reduces investment costs significantly.
The R and S FSH18 handheld spectrum analyser from Rohde and Schwarz underscores the company's continued development of the 3 and 6GHz models of the R and S FSH, already firmly established on the market.
These models are highly regarded by users especially because of their extensive measurement functions, excellent RF characteristics, and compact design (2.5kg).
Accommodated in the same housing as the low-frequency models, the R and S FSH18 is ideal for a variety of applications in the microwave range.
In field use, this newcomer helps to detect spurious signals in a frequency range up to 18GHz - no matter whether in tests on radar equipment, air traffic control systems, satellite systems, or microwave links.
Plus, it covers the complete frequency range for WiMAX, thus providing a cost-effective solution for spectrum measurements in this field.
To enable users to perform complex measurements on radar and mobile radio signals, Rohde and Schwarz offers its R and S NRP-Z81 broadband power sensor.
For the first time, an RF detector, analogue and digital signal processing, as well as the entire evaluation logic of a peak power meter are combined in a compact sensor that can be directly remote-controlled via USB.
By featuring video bandwidth of up to 30MHz and a rise time of 13ns, the R and S NRP-Z81 allows high-resolution envelope analyses.
Complete statistical analysis of a signal can be performed within only a few milliseconds.
For average power measurements, it provides a dynamic range of 80dB.
The instrument's frequency range extends from 50MHz to 18GHz.
The R and S ESU from Rohde and Schwarz is a new family of CISPR16-1-1-compliant EMI test receivers that meets all civil and military standards for electromagnetic interference measurements.
A new, FFT-based test method considerably speeds up measurements.
The time-domain scan allows users to perform overview measurements more than 100 times faster than with existing EMI test receivers.
The instrument also features comprehensive test functions, a complete set of parallel detectors including the new CISPR-RMS detector, RF scan, IF analysis, and a flexible report layout function.
