Burnham, UK–December 13, 2006–Aeroflex has announced it has added the ability to undertake live receiver testing and transmitter testing, including HSDPA on its highly successful 6413A UMTS basestation test system. The capability is ideal for the ongoing maintenance of UMTS basestations to ensure they perform to specification. It enables testing to be undertaken without any disruption to live traffic caused by taking the basestation out of service.

The performance of the basestation receiver is extremely important as it essentially defines quality of service in a cell. With the low operating power of mobile terminals, the performance of the receiver has to be exceptionally good at all times. A poorly performing basestation receiver will result in an increased number of calls being dropped due to lower sensitivity and signal quality. Phones will be required to transmit at higher power, impacting battery life and potentially causing signal interference. It will also make it difficult for revenue generating higher data rate services to be used. A poorly performing basestation will also significantly impact network planning as the number of calls a cell can handle will be restricted. Conversely, a 1dB improvement in basestation receiver sensitivity, for example, can mean that 11% fewer basestations are required in network (source: WCDMA for UMTS by Harri Holma and Antti Toskala (Wiley 2004)).

The Aeroflex 6413A UMTS basestation test system is designed specifically for the installation and commissioning, maintenance, fault-finding, performance verification and optimization of radio basestations. A single-box portable solution, it is able to take complete control of the basestation via the Iub interface and perform all of the critical transmitter, receiver and functional tests without external control equipment or the need for detailed knowledge of the basestation's operation and control.

The addition of a live receiver and transmitter testing capability to the Aeroflex 6413A UMTS basestation test system compliments its existing Iub-controlled test mode which facilitates the implementation of repeatable test scenarios in controlled environments based on the methods defined in the ETSI standard 3GPP TS25.141. The Aeroflex 6413A's user interface is intuitive to use. Based around an embedded PC and using touch-screen controls, all functions can be operated from the front panel. Measurement results can be viewed while tests are running or stored for later analysis. Tests can be run manually or automatically using pre-programmed test sequences.

"The addition of live receiver and transmitter testing to the Aeroflex 6413A will considerably improve its appeal to network operators," said Ross Broadhurst, Product Marketing Manager at Aeroflex Test Solutions. "Network operators will now be able to test basestation performance and optimize their network quality of service without adversely interfering with the live traffic on the network."

In order to view a computer screen image remotely or with multiple monitors, VGA distribution or signal extension devices are commonly used. Since these extension signals are analog, there are problems including image quality deterioration caused by inferior signals and restrictions on cable length and number of monitors that can be viewed.

With CONTEC's FlexNetViewer, users can easily distribute VGA images with no quality deterioration even when viewed over a long distance. FlexNetViewer converts VGA output to a LAN packet and sends the digital signals via Ethernet. Both transmitter and receiver include serial I/O for remote use of multiple RS-232C-compliant touch panel monitors. Users can also send VGA signals to multiple receivers and receive them from multiple transmitters by installing the application utilities on to their computer.

When using both transmitter and receiver, monitors can be connected in a 1:1 or 1:N configuration without requiring specific computer hardware or operating system.

EXTENDS ALLOWABLE DISTANCE BETWEEN PC AND MONITOR VIA ETHERNET

• When the cable length between a PC and monitor is limited, it can be easily extended by using commercially-available Ethernet cable (category 5 or higher).

• RGB image signals are converted into LAN packet signals before being transmitted. This prevents deterioration of the image data even when transmitted over a long distance.

SIMPLIFIES MULTI-MONITOR CONFIGURATIONS

• Using multiple receivers allows the image shown on the transmitter monitor screen to be shown on multiple monitors simultaneously. This requires the same number of receivers (RP-VL-R-01) as monitors.

NO NEED FOR SPECIFIC HARDWARE OR OPERATING SYSTEM

• When using both the transmitter (RP-VL-S-01) and receiver (RP-VL-R-01), transmitting screen images does not depend upon a specific platform (hardware or operating system). The same screen images can be sent to monitors in a 1:1 or 1:N configuration without requiring complicated utility setups.

APPLICATION UTILITIES ALLOW HOST PC TO FUNCTION AS SYSTEM TRANSMITTER OR RECEIVER

• By installing application utilities, the PC can serve as a transmitter for multiple receivers or as a receiver for multiple transmitters.

INCLUDES REMOTE SERIAL AND DIGITAL I/O

• Both the transmitter (RP-VL-S-01) and receiver (RP-VL-R-01) convert serial and digital I/O data into LAN packet signals before transmission.

• Application utilities enable remote serial I/O communications with RS-232C-compatible devices when connected to the receiver.

• An RS-232C-compatible touch panel can also be used to extend the distance between the PC and touch panel.

• Application utilities enable the PC to control the digital I/O (4channels non-isolated LVTTL level input, 4channels non-isolated LVTTL level output), on both the transmitter and receiver.

UTILITIES FOR IMAGE DISPLAY AND MAIN UNIT SET-UP

• Operating environment – Windows Vista, XP, 2000

• Installation of the image display utility enables the PC to be connected directly to either the transmitter (RP-VL-S-01) or the receiver (RP-VL-R-01) when displaying screen images. The user can them display screen images from one PC onto multiple monitors or to display screen images from multiple PC monitors onto one split screen monitor.

• The main unit setting utility is used for setting the IP addresses of the transmitter (RP-VL-S-01) and receiver (RP-VL-R-01), set-up of remote digital (DIO) and serial I/O (SIO) and communication specifications.

FUNCTION LIBRARIES

• The features used in the image display utility are available in the function library allowing users to develop custom applications.
  

OPTIONAL LCD MONITOR MOUNTING

• An optional adaptor is available to mount the receiver on the back of an LCD monitor.

• VESA-compliant (75mm x 75mm or 100mm x 100mm).

CONTEC's FlexNetViewer is ideal for a variety of applications, including multiple monitor displays in an adjacent lecture hall, informational kiosks in public areas, real-time digital billboards or in a manufacturing facility to view the same screen outside and inside of a clean room.

CONTEC's FlexNetViewer components are lead-free (exceeding JEITA Phase 2 requirements) and RoHS-compliant.

MIL-RAM utilizes 902- 928MHz frequency hopping spread spectrum technology to link any field-installed 4-20mA transmitter with new or existing control systems (controllers, PLC's, etc.) accepting standard 4-20mA inputs. One or more radio transmitters (MPT900T) are installed in the field and each can accommodate up to eight 4-20mA transmitter inputs. Each field radio transmitter (designed for hazardous or ordinary locations) converts the 4-20mA signals (16-bit, high resolution A/D conversion) into wireless data (sensor readings) and sends the data packets to a radio receiver (MPT900R) located at the control system. This receiver converts the wireless data back to discrete 4-20mA analog outputs for direct connection to control system. The MIL-RAM system simply and reliably replaces the wire that traditionally interconnects the 4-20mA transmitter and control system. A MIL-RAM wireless installation provides tremendous cost savings as installation costs associated with hard-wired systems can greatly exceed the cost of the equipment. The MIL-RAM Multi-Process Wireless Telemetry System is practical and cost effective for small systems consisting of only a few monitoring points up to much larger systems utilizing several hundred remote points. Distances between the field installed 4-20mA transmitter and control system can exceed 20 miles line-of-sight. Actual distances depend on antenna selection and specific factors in the environment (buildings, structures, terrain, etc.). Signal repeaters (MPT900RP) are available to extend distances especially in areas where line-of-sight installation is not possible. Additionally, field installed 4-20mA transmitters and radio transmitters can be powered by solar panels in the event local power is not readily available or practical.

The MIL-RAM Wireless Telemetry System is Multi-Process in that any 2-, 3- or 4-wire field installed process transmitter/transducer (temperature, pressure, humidity, flow, pH, conductivity, etc.) that generates a 4-20mA signal can be equipped with a radio transmitter and the data continuously sent to the control system via wireless communications. The radio transmitters/receivers utilize advanced data recognition techniques to ensure data reliability and integrity; corrupt data is automatically rejected. The radio transmitters/receivers have LCD displays for easy configuration which simply involves selection of specific addresses for each field installed 4-20mA transmitter. Addressing provides a unique identity for each 4-20mA transmitter to eliminate cross-talk interference with other devices. The Wireless radio transmitters/receivers are quickly and seamlessly integrated into any new or existing control system to provide continuous and reliable data links between field installed transmitters and the control system.
