Aim-TTi PSA1303 1.3GHz Handheld Spectrum Analyser

The Aim-TTi PSA1303 Handheld RF Spectrum Analyser is designed for field engineers who need a compact, rugged, and highly capable instrument. Covering a frequency range from 1MHz to 1300MHz, it offers a typical noise floor of –115 dBm and resolution bandwidths from 300Hz to 10MHz, enabling precise measurement of weak and complex signals. Its 4.3 inch colour TFT display with a hierarchical menu system provides quick access to all major functions, assisted by hard keys for marker control and frequently used operations. This portable analyser delivers rapid start up, with the first sweep available in under two seconds.

The PSA1303 has a comprehensive set of measurement features, including AM/FM audio demodulation in zero span mode, trace modes such as normal, peak hold, and averaging, and twin markers with absolute and delta readouts. The instrument supports multiple measurement units (dBm, dBµV, mV, µW), offers smart peak tracking, and includes a frequency counter with 10Hz resolution and auto find capability for locating major signals. With 1.8GB of internal memory and USB connectivity for flash drives and PC interfacing, it allows extensive storage and easy data export. Battery life extends up to six hours of continuous use, making it highly practical for field deployment.

Typical applications include interference analysis, antenna alignment, signal strength mapping, covert transmitter detection, spurious emissions checks, and EMC related frequency evaluations. The rugged casing, removable sun shield, and compact 0.58kg form factor make the PSA1303 particularly suitable for outdoor and mobile diagnostic work.
