tinySA Spectrum Analyzers and Signal Generators

The tinySA is a compact, low-cost handheld spectrum analyzer and RF signal generator designed for hobbyists, radio amateurs, educators, and engineers. It comes in three different variants and can be used for RF debugging, signal inspection, interference hunting, filter testing, antenna-related measurements, and basic RF education, both in the field and on the bench. The product line includes the tinySA Basic, tinySA Ultra, and tinySA Ultra+, which mainly differ in their supported frequency ranges and performance. The tinySA Basic supports 100 kHz to 350 MHz on its low input and up to about 960 MHz on the high input, while the Ultra and Ultra+ models can observe signals up to 12GHz. The devices run from an internal rechargeable battery with USB-C charging, support firmware updates, internal self-test and calibration routines, marker and peak detection, configurable frequency span and amplitude settings, and PC control over USB. Input protection limits are specified at +10 […]
