TinySA Ultra+ZS407 Spectrum Analyzer 4″ Handheld 100kHz‑7.3GHz with

Description

Product Overview

The 2025 TinySA Ultra+ZS407 is a next‑generation handheld spectrum analyzer designed for precision RF testing across a remarkably wide frequency span. Featuring a 4.0‑inch 480 × 320 pixel capacitive touchscreen, the device offers intuitive navigation, real‑time waterfall displays, and on‑screen marker controls. Its measurement range stretches from 100 kHz up to 7.3 GHz, covering MF, HF, VHF, UHF, and emerging 5G bands. A built‑in 32 GB microSD card provides ample storage for trace logs, screenshots, and firmware updates. The unit also doubles as a signal generator, delivering sine, square, and dual‑tone outputs from 0.1 MHz to 900 MHz (square up to 6.3 GHz), making it a versatile 2‑in‑1 tool for both analysis and synthesis.

Usage

Engineers, field technicians, hobbyists, and educators can employ the Ultra+ZS407 in a variety of scenarios. In a lab environment, it serves as a quick‑check instrument for antenna tuning, filter verification, and component characterization. On‑site, its lightweight 13.76‑ounce chassis and rechargeable lithium‑ion battery enable uninterrupted measurements in remote locations, such as tower sites, vehicle installations, or emergency‑response setups. The device’s USB‑C interface allows seamless PC integration for extended data analysis via the Tinysa‑APP, while the included SMA cables and adapters simplify connection to a wide range of antennas and test fixtures.

FAQ

What is the minimum RBW setting?

The Ultra+ZS407 can achieve a resolution bandwidth as low as 200 Hz, allowing you to resolve closely spaced signals and perform detailed inter‑modulation analysis.

Can the device operate without a PC?

Yes. All core functions, including spectrum scanning, signal generation, and data logging, are available directly on the handheld unit via the touchscreen interface.

Is the built‑in battery replaceable?

The device ships with a rechargeable lithium‑ion battery that is user‑replaceable. Spare batteries are sold separately for extended operation.

How does the USB‑C interface work?

The USB‑C port follows the CDC protocol, allowing the analyzer to appear as a virtual COM port on a PC. Through the Tinysa‑APP you can stream live data, export logs, and update firmware.

What accessories are included?

Each package contains the Ultra+ZS407 unit, two 30 cm ALSR100 SMA cables, a USB‑C data cable, an SMA‑SMA barrel connector, a TL‑anyard with touch plectrum, an SMA‑connector antenna, and a pre‑loaded 32 GB microSD card.
