VTI Instruments Corporation has introduced the EX1200-7416, a transient capture and time-stamp module that extends the capabilities of the EX1200 Series of configurable LXI Class A instruments. The new module supports a broad range of applications that require level comparison, event detection, and time stamping.

TTi has improved its BS407 micro-ohmmeter by increasing its accuracy at the lowest values of resistance. The BS407 can resolve resistance down to 1 microhm, and has ranges with full scales from 2 milliohms up to 20 kilohms with a basic accuracy of 0.1%. It uses a 4-terminal measurement system via high quality Kelvin clip leads, and has a maximum excitation current of 250 mA. Current reversal can be selected to identify errors from thermal EMF.

TTi has upgraded its well known EX354D bench power supply to improve its precision. The new model, the EX354RD, has 4-digit meters for both voltage and current along with switchable remote sense terminals. The EX354RD has two independent and isolated outputs of 0-35 V at 0-4 A. Separate meters are provided for voltage and current on each output, providing resolutions of 10 mV and 1 mA, respectively. The outputs can be wired in series or parallel ...

TTi has extended its range of USB RF and microwave power meters with the release of the TTi-Satori ST265. The new instrument pushes the frequency limit for high dynamic range USB power meters up to 26.5 GHz. The ST265 now covers a frequency range of 10 MHz to 26.5 GHz.

The new QPX1200L from TTi is a revised version of the company’s PowerFlex regulated 1200 watt power supply unit with extra features including an extended remote control interface option. The new unit incorporates an LXI compliant Ethernet interface that can provide a low-cost alternative to GPIB in many system applications.

In response to changing industry demands, the Dynaload division of TDI Power has developed a new line of electronic loads. The Dynaload XBL Series features 800, 2000, 4000, and 6000 W models with a wide range of voltage inputs and sophisticated computer programming via GPIB, Ethernet, or RS232. These units also feature an integrated web page for local system operation and control.

The new counter has a frequency range from 0.001 Hz to over 3000 MHz with high sensitivity across the range. The high-quality TCXO timebase is stable to within ±1 part in 106 over the full temperature range, and provides a low aging rate. Its short warm-up time allows accurate measurements to be made even under portable battery-powered conditions.

The TTi PL-P(G) Series of ultra-compact linear regulated power supplies incorporate five types of remote-control interface making them suitable for an unusually wide range of applications. The interfaces include GPIB, USB, RS232, Ethernet (LXI) and analogue. USB and RS232 are most likely to be used for small systems or single PC control, while GPIB and LXI are more appropriate for larger system use.

The new EX355R from TTi is a compact laboratory bench-top power supply generating voltages from 0 to 35 V at currents from 0 to 5 A. Unlike other power supplies of similar power levels, it uses entirely convection-based cooling and is consequently silent in operation.

The QPX1200 auto-ranging DC power supply from TTi is now available with a LAN interface in addition to USB and RS-232. The QPX1200 is a 1.2 kW unit featuring PowerFlex regulation. This enables it to offer voltage and current combinations between 60 V/20 A and 20 V/50 A, making it suitable for a very wide range of applications.

The new Sorensen XG Series of DC power supplies offers the highest power level currently available in a 1U half-rack casing. The 850 W of output power is provided in 12 different models with maximum output voltages up to 600 V and currents up to 110 A. High-frequency soft-switching technology is used to provide low output noise coupled with high power efficiency. This technology also minimises the stress on the switching devices, thus providing h...

TTi Instrument Distribution has announces the acquisition of the programmable power business of Xantrex Technology by AMETEK, Inc. for $120 million in cash. Based in San Diego, California, USA, the Xantrex Programmable Power division is a leader in AC and DC programmable power supplies, with annual sales of approximately $80 million.

The EL302RT from TTi is a triple-output laboratory power supply which incorporates switchable remote sense terminals that enable the output voltage to be precisely controlled at the load end. Remote sensing is essential to maintaining precise regulation and true metering of the load voltage. Many other power supplies omit remote sense, and quote regulation figures that could never be achieved in practice.

Now available from TTi, the Tektronix DPO3000 Series is a family of lower-cost mid-performance oscilloscopes incorporating the long record length needed for serial data analysis in embedded systems. All DPO3000 models incorporate a 5 megasample record length on each channel and can sample at up to 2.5 GS/s on all channels simultaneously. Two- or four-channel models are available with bandwidths of 100 MHz, 300 MHz or 500 MHz.

The new APx585 from Audio Precision is the only audio analyser in the world capable of interfacing with HDMI and Blu-ray disc audio. With the APx HDMI option, engineers can now use the same familiar Audio Precision tools to measure HDMI audio quality and audio format compatibility on devices such as surround sound receivers, set-top boxes, HD TVs, and DVD and Blu-ray Disc(tm) players.
