TTi (Thurlby Thandar Instruments) is a leading manufacturer of electronic test and measurement instruments. These products are sold throughout the world via carefully selected distributors and agents in each country.
An initial AC and DC power platform launch from AMETEK is for its California Instruments AsterionTM AC Power Source, available in 500VA, 750VA and 1500VA power levels. It is available from TTi. The Asterion offers up to 1500VA in a 1U height package. At its heart is AMETEK’s powerful new iX2 current-doubling technology.
The new RSA500 and RSA600 series of analysers from Tektronix, available at Ttid, offer frequency coverage from 9 kHz up to 7.5 GHz with 40 MHz acquisition bandwidth, a measurement dynamic range from -161 dBm/Hz Displayed Average Noise Level, and up to +30 dBm maximum input.
The PA3000, a 1- to 4-channel AC/DC power analyser from Tektronix optimised for testing single- and multi-phase, high efficiency AC-DC and DC-AC power supply designs is available from TTid. The analyser offers 10 milliwatt standby power measurement capabilities and a 1MHz bandwidth with mid-range pricing.
Aim-TTi has added a 6GHz version of their best selling TF900 series of bench/portable frequency counters. The TF960 has a TCXO timebase, can measure and count between 0.001Hz and 6000MHz, and incorporates a USB control interface. The TF960 can measure frequency, period, pulse width, duty cycle and frequency ratio, as well as event counting (totalise).
Aim-TTi has introduced a lower-cost version of the company’s best-selling QPX1200 series laboratory power supply. The new model is designated QPX1200S and is intended for applications where digital remote control is not needed.
Aim-TTi has launched an entirely new type of current probe which is cable of measuring currents in PCB tracks. The Aim I-prober 520 positional current probe uses a patented technology to observe and measure current without the need to break or surround the conductor.
The TF930 3 GHz low-cost universal frequency counter from Aim-TTi now incorporates a TCXO (temperature-controlled crystal oscillator) timebase, giving it a stability within ±1 ppm over its full operating temperature range, combined with a low aging rate. The UK price is £251 (plus VAT).
TTid has been appointed by N4L to provide distributor support in the UK for the new PPA1500 Series of power analysers. The PPA1500 has been introduced to meet the increasing demand for smaller and more efficient products. This push for greater efficiency has resulted in the development of power conversion techniques of ever-increasing frequency, and with these new techniques comes the need for power measurement instruments with superior wideband performance and higher accuracy.
The new TG5011G from Aim-TTi is a combined function/arbitrary/pulse generator with a frequency range covering 1 µHz to 50 MHz. The new model has a GPIB interface in addition to the USB and LAN (LXI) interfaces of the standard model.
Sorensen has extended the DLM600 series of high-density programmable DC power supplies to cover voltages up to 300 V and currents up to 75 A. The DLM600 provides up to 600 W of power with unusually low levels of both differential and common-mode noise.
The new QPX600D from Aim-TTi is a dual-output 1.2 kW power supply using the company’s latest PowerFlex+ regulation technology to provide up to 80 V or up to 50 A on each 600 W output.
Whereas a conventional power-supply unit has a fixed current limit giving a power capability that decreases directly in proportion with the output voltage, the PowerFlex+ design of the QPX600D enables higher currents to be generated at lower voltages within an overall power limit envelope.
The new GaGe CS1250X is a range of 12-bit single- and two-channel 500 MS/s digitiser cards with 350 MHz of input analogue bandwidth. Designed for high-speed data-acquisition applications, the new cards provide the highest available ENOB (effective number of bits) performance at high signal frequencies that is available on the market.
The TTi HA1600A mains and harmonics analyser has been updated to include a full implementation of the two alternative special assessments for Class C Discharge Lighting equipment below 25 W, as specified in EN61000-3-2.
TTi (Thurlby Thandar Instruments) has launched a lower-cost version of the best-selling TG5011 function/arbitrary/pulse generator. The new TG2511 has a maximum frequency of 25 MHz for sine and square waves and costs only £795. It offers similar facilities to the more expensive 50 MHz generator, but with proportionately lower maximum frequencies for pulse and arbitrary waveforms.
Now available in the UK from TTi Distribution, the Sorensen SGI Series represents the next generation of high-power programmable DC power supplies, designed for exceptional load transient response, low noise and the highest power density in the industry.
The TG1000, new from TTi, is a 10 MHz function generator using direct digital synthesis (DDS) yet costing less than £400. Direct digital synthesis delivers low-distortion sine waves with improved spectral purity in comparison with analogue function generators. Frequency stability and phase noise are excellent, and absolute frequency accuracy is equal to that of the crystal based master clock.
