TTi has replaced its best-selling EL302T triple-output laboratory power supply with a new model that incorporates a fully variable third output.
TTi (Thurlby Thandar Instruments) has replaced its best-selling EL302T triple-output laboratory power supply with a new model that incorporates a fully variable third output. The new EL302Tv is a linear regulated power supply with dual outputs of 0 to 30V at 0 to 2A. The third output is now continuously variable between 1.5 and 5.0V at currents of up to 2A, replacing the fixed 3.3/5V at 1A auxiliary output of its predecessor.
A 'push to measure' button allows the right-hand displays to show the settings for the auxiliary output, enabling the voltage to be set accurately without the need for an external meter.
The model change reflects the increasing use of low-voltage circuitry in most areas of electronics and the move away from standard operating voltages.
The price of the EL302Tv remains at GBP 305 (plus VAT), unchanged from that of the model it replaces.

Agilent Technologies has introduced what it believes to be the industry's first oscilloscope-based DDR2 compliance test application.Agilent Technologies has introduced what it believes to be the industry's first oscilloscope-based DDR2 compliance test application, ideal for engineers working in the computer, data storage, electronic data processing and consumer electronics industries. The Agilent N5413A DDR2 test application, which runs on Infiniium 54850 and 80000 Series oscilloscopes, provides DDR2 electrical compliance measurements based on the Joint Electronic Device Engineering Council (JEDEC) JESD79-2C DDR2 SDRAM Specifications and INTEL DDR2 667/800 JEDEC Specification Addendum Rev.1.1. The N5413A also features Advanced Debug mode, which provides crucial measurements such as eye-diagrams, mask tests, ringing measurements and other tests not covered in the JEDEC specifications that help engineers discover the root causes of problems in their designs.
DDR2 memory technology is an evolutionary upgrade to its predecessor, DDR.
DDR2 devices will feature higher bandwidths and smaller chip footprints and will consume less power and generate less heat.
'Adoption of DDR2 among system OEMs and system integrators is increasing, and we expect interest to continue accelerating into 2007,' said Jay Alexander, vice president and general manager of Agilent's design validation Division.
'We are pleased to be able to offer engineers the tools they need now for testing, debugging and characterizing DDR2 designs quickly and easily'.
With the N5413A DDR2 compliance test application, engineers can use an ordinary oscilloscope to perform automated testing and margin analysis.
The application automatically configures the oscilloscope for each test and provides informative reports.
It includes margin analysis that indicates how closely the device passes or fails each test.
When engineers conduct DDR2 tests, they may encounter difficulties connecting to the target device, configuring the oscilloscope, performing the tests and analysing the measured results.
The DDR2 compliance test application guides users through these steps and does most of this work for the user.
If a designer discovers a problem, the Advanced Debug feature in the test application and debug tools in the oscilloscope are available to aid in root-cause analysis.
The Advanced Debug functionality includes a unique technique that separates read/write burst signals on the same bus, which gives engineers a powerful tool for debugging their designs.
With the increasing data rate and decreasing window validity time of DDR2 memory systems, signal integrity performance of the measurement tools becomes critical to achieving accurate and repeatable measurements.
The advantages of Agilent's Infiniium 80000 Series award-winning oscilloscopes and InfiniiMax probing include the industry's lowest noise floor, lowest jitter measurement floor, lowest trigger jitter and flattest frequency response.
Superior signal integrity in measurement tools maximises DDR2 design margins.
The JEDEC Solid State Technology Association is the semiconductor engineering standardisation body of the Electronic Industries Alliance (EIA), a trade association that represents all areas of the electronic industry.
Current Agilent N5413A DDR2 clock characterisation application owners can upgrade to the new DDR2 compliance test application at no cost.

Aeroflex has announced that it has added the ability to undertake live receiver testing and transmitter testing including HSDPA on its highly successful 6413A UMTS basestation test system.
Aeroflex has announced that 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 as 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 increasing 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 base station 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 optimisation 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 environment 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 optimise network quality of service without adversely interfering with the live traffic on the network'.
