Compact bench power supply provides 175W
The EX355, new from TTi (Thurlby Thandar Instruments), is a single-output laboratory DC power supply providing an output from 0 to 35V at 0 to 5A.
Programmable power-supplies offer outputs to 1kW
The XHR range of programmable power supplies, offering output ratings up to 1 kW is power-factor corrected for low current draw and reduced generation of input current harmonics.
It also offers an intuitive user interface and graphical display that makes it extremely easy to use.
The PM 6690 combines a speed of 12 digits per second for frequency measurements with 100ps single-shot time resolution.
Phase measurements are carried out at a resolution down to 0.001 degrees and are speeded up by a "single pass" technique.

Programmable synthesised 1GHz RF generator
The TGR1040GP from TTi (Thurlby Thandar Instruments) is a programmable synthesised RF signal generator with a frequency range up to 1GHz.
The instrument can acquire and store up to 250,000 measurements per second, and 2000 measurements per second can be made over the built-in bus interfaces.
The internal memory can hold as many as 750,000 measurement results for further analysis.
The menu-driven instrument control structure reduces the risk of mistakes.
The main measurement result is supported by auxiliary parameter readings, which eliminate the need for other instruments like a DMM or an oscilloscope.
The phase relationship between the input and output signal of a device can be measured while the user simultaneously reads the test frequency of the signal and the voltage ratio (in decibels) between the input and output signals.
The graphical presentation of results using histograms and trend curves gives a clear understanding of random signal distribution and of system changes over time.
Auto-trigger automatically sets the optimum trigger level and hysteresis for the actual signal applied.
The PM 6690 incorporates a graphical display which presents the measurement results in numerical (up to 14 digits) or graphical format.
The display is also used to present the setup information as part of a convenient, menu-driven control system.
The display gives the main measurement as well as auxiliary measurement results, so that commonly asked questions like "what is the attenuation and phase shift of this network?" are answered directly by a single look at the display.
The results of statistical analysis can be presented as numerical data, as a trend graph, or as a histogram, giving an insight into the behaviour of the device under test without the help of external processing.
The PM 6690 is equipped with both GPIB/IEEE488 and USB interfaces for high-speed communications with a PC.
The GPIB interface allows easy integration in larger test systems.
Alternatively, the USB interface can be used for rapid communications with a PC in smaller test setups.
