U.S. technical distribution firm Saelig has announced the introduction of new Aim-TTi PSA Series 3 RF spectrum analyzers, offering improvements over the previous Series 2 instruments that include a lower noise floor for increased sensitivity, a new frequency counter, additional RMS, sample, and average detector modes, and RBW selectable down to 300 Hz.
Available in 1.3 GHz and 2.7 GHz versions, the handheld PSA Series 3 analyzers incorporate a 4.3-inch (11cm) backlit TFT color touch-screen display with a rechargeable Li-ion battery stated to provide more than three hours of continuous operation per charge. Model PSA1303 has a frequency range of 1 MHz to 133 GHz while the PSA2703 operates up to 2.7 GHz, both offering a noise floor stated to be as low as -115 dBm and a dynamic range of 84 dB.
Features include sweep modes (continuous, single, peak hold and sweep average), AM/FM audio demodulation with built-in speaker, and data logging for traces, data points, or screen images (with storage for 10,000 entries per file triggered from a key press, internal timer, external trigger, or the limits comparator). Traces or complete screen images can be saved to file and compensation tables for antennae or other external transducers can be created and loaded.
USB host and device connectors allow the use of USB Flash drives or direct connection to a PC. Control of PSA Series 3 analyzers is by finger-operated touch-screen soft keys in a hierarchical menu system that gives rapid access to menu functions. Additional hard keys are provided for marker movement and short cuts to all major functions.
PSA Series 3 RF analyzers weigh 20 ounces and are 3.6 inches wide, making them suitable for portable RF service kits. The ruggedized case incorporates a rubber protection buffer, a bench stand, and screen protection. For bench-top use, units can be operated continuously from their AC chargers. Battery life can be further extended by selecting auto-off which turns the instrument off (retaining all data) after a selectable delay of 5 to 60 minutes from last key press.
