✅ Store logs and measurements directly on the device so you can review and manage data whenever needed.

✅ Carry a single compact tool that reduces the need for bulky benchtop equipment, helping you stay agile and efficient.

Explore detailed RF behavior with a portable tool that adapts easily to hobby, lab, and field workflows.

The TinySA Ultra is built for precision, offering low noise performance and refined filtering that help you capture clean, reliable measurements. It reaches noise levels around -89dBm on average and supports an internal LNA up to 4GHz for improved sensitivity when analyzing weak signals. Fine-tuning your view is simple with selectable resolution filters ranging from 200Hz to 850kHz, available in 1, 3, or 10 step adjustments.

Its output capabilities make it useful not only for observation but also for generating test signals. You can produce sinusoidal outputs up to 800MHz or square waves reaching 4.4GHz, giving you flexibility when exploring circuits, antennas, or RF modules. Output power ranges from -104dBm to -16dBm, suitable for a wide variety of low-power experiments.

Despite its compact footprint, the analyzer provides strong connectivity options. USB Type‑C and UART‑TTL interfaces allow easy integration with computers, firmware tools, and automation setups. The ergonomic 117×72×23mm housing fits comfortably in the hand and travels effortlessly in a bag or toolkit.

Scan performance is responsive, with up to 450 points per sweep and scan times as short as 165ms in lower bands. When you need to study modulation or time‑based behavior, zero‑span mode offers fast response at around 17ms.

A wide accessory set supports immediate use: SMA cables, an antenna, a barrel connector, a data cable, a lanyard, a touch plectrum, and a preinstalled microSD card for convenient storage.

The device's design makes it easy to bring RF testing into any workspace, from benches to field sites.

Use the included cable whenever you need fast data transfer or firmware access.

SMA cables help you connect antennas, modules, and signal sources cleanly and securely.

The barrel connector offers quick coupling for RF chains or test setups.

The supplied antenna lets you start capturing signals right out of the box.

These small accessories make handling the device easier during long sessions.

The large-capacity card supports extensive logging without frequent file management.

Everything in the kit is organized to help you start measuring and exploring RF signals immediately.

Enhance your toolkit with a portable analyzer that helps you solve challenges faster and more effectively.
