Brief Summary The PSA-T series (PSA1301T and PSA2701T) are fully portable spectrum analyzers incorporating a handheld computer (a Palm T|X). They are sufficiently small and lightweight to be operated as a handheld instrument and has a typical battery life of four hours from each charge. Alternatively they can be used as bench instruments using the supplied mains adaptor/charger. They can be set horizontally or vertically, or at an angle of about 25 degrees using the built-in tilt stand. The spectrum analyzer has a frequency range of 0.15 MHz to 1300 MHz (PSA1301T) or 1MHz to 2700MHz (PSA2701T). The span can be set anywhere between 0.320 MHz and 1299.850 MHz (PSA1301T) or 2699.000 MHz (PSA2701T) with a resolution of 1kHz. Start, stop or centre frequencies can be set to the same resolution. The resolution bandwidth is selectable as 280 kHz or 15 kHz (PSA1301T) or 1 MHz, 280 kHz or 15 kHz (PSA2701T). The on-screen amplitude range is 80 dB with a reference level of -20dBm or 0dBm. Amplitudes can alternatively be displayed in dBμV. Vertical magnification to 5dB/div can be selected. Average noise floor is better than -90dBm at -20dBm reference level and 15 kHz RBW. Sweeps can be continuous, single shot, peak hold or average (2 to 256 sweeps). Sweep time is defined by the span and resolution bandwidth, and varies between 0.1 sec and 30 sec. A zero span mode is available with AM or FM audio demodulation. Twin vertical marker lines are available giving a readout of frequency and amplitude to a resolution of 0.1 kHz and 0.1 dB. Markers can be manually positioned or automatically peak finding and tracking. A reference trace can be displayed in addition to the live trace. Limit lines can also be created and displayed. The graticule is fully controllable. Any number of traces can be stored to permanent memory for recall to the screen or for data export. Limit lines, instrument set-ups and complete screen bitmaps can also be stored. Battery life depends upon screen brightness, but is around four hours of continuous operation from a charge. To conserve the battery, auto-sleep mode can be selected whereby the unit turns off automatically after a defined period from the last key press. All data is retained when off. Pressing the Help hard key brings up a help screen relevant to the current menu position.
