The AIM-TTI Instruments PSA2702 is a fully portable RF spectrum analyzer that incorporates a high resolution color TFT touch screen. It is sufficiently small and lightweight to be operated as a true handheld instrument and has a battery life of more than eight hours from each charge. The on-screen amplitude range is 85 dB with a reference level of -20dBm or 0dBm. Amplitudes can alternatively be displayed in dBμV. Vertical magnification down to 1dB/div can be selected. Average noise floor is better than -95dBm at -20dBm reference level and 15 kHz RBW (video filter on).
Specifications.
Frequency Measurement.
Frequency Span;
Frequency Range: 1 MHz to 2700 MHz in one range.
