Portable Spectrum Analyzers

TTi Portable Spectrum Analyzers PSA1301T and PSA 2701T
Big on performance, Small on size and cost The PSA-T series is an entirely new type of instrument. It utilises the power of a handheld computer* to provide a level of performance that was previously impossible for an instrument of this small size and low cost.
A fully integrated instrument. The PSA-T series incorporates the handheld computer within its housing to create a single integrated instrument. The unit is very compact and lightweight. It fits easily into the hand and takes up very little room within a toolkit. Access to the USB port of the handheld computer is provided within the body of the instrument, and all of the functionality of the Palm T\|X is retained. High resolution display. The Palm T\|X handheld used with the PSA-T series has a high brightness 3.7” (9.5 cm) TFT screen capable of displaying 65,000 colours. Despite it’s small size it has a resolution of 320 x 480 pixels (half VGA), giving it twice the total pixels of the quarter VGA displays used by many bench-top instruments. The graticule area of 320 x 300 pixels compares with a figure of 260 x 200 for a typical spectrum analyzer. This allows the PSA-T series spectrum analyzers to show more sample points at a higher vertical resolution. Extended battery operation. The PSA-T series operates from rechargeable batteries that can provide more than four hours of continuous operation. To conserve battery life, it can be turned on or off by a single key press. The unit can also be set to switch off automatically after a set time from the last action. For continuous bench top operation it can be powered from its AC adaptor which also recharges the batteries in less than 4 hours. Unlimited data storage. By its use of interchangeable flash memory cards, the PSA-T series can store thousands of waveforms, instrument set-ups, or complete screen images. Waveforms, set-ups and screens can be saved with either default file names or with user defined names using the alpha-numeric keypad. * The PSA1301T and PSA2701T incorporate a model T\|X handheld computer from Palm - for more details visit www.palm.com
