2-in-1 Handheld Tiny Spectrum Analyzer 2.8/4inch Display Signal Generator Portable Spectrum Analyzer 100kHz-350MHz with 32GB Card Upgraded V0.3.1 with ESD Protect MF/HF/VHF UHF Input
Feature:
1.Wide Frequency Range: Our mini handheld tiny spectrum analyzer covers an extensive range of frequencies, with high-quality MF/HF/VHF inputs from 0.1MHz to 350MHz and a lower-quality UHF input from 240MHz to 960MHz. Whether you're working with low or high frequencies, this device has got you covered.
2.Built-in Calibration Signal Generator: Not only does this portable spectrum analyzer function as a spectrum analyzer, but it also doubles as a signal generator. The MF/HF/VHF outputs sinusoidal signals between 0.1MHz and 350MHz, while the UHF output provides square wave signals from 240MHz to 960MHz. The built-in calibration signal generator ensures accurate self-checks and low-input calibration.
3.Versatile Filtering and Scanning: Switch between different resolution bandwidth filters, allowing you to fine-tune your analysis between 2.6kHz and 640kHz. The color display screen of spectrum analyzer provides 290 scan points, covering the entire low or high-frequency range. With its compact size and rechargeable battery, the tinySA is your portable scanning solution, offering at least 2 hours of continuous usage.
4.Enhanced Performance with ESD Protection: The latest version 3.1 of our mini spectrum analyzer guarantees improved stability and sensitivity. Additionally, it now features ESD protection, providing higher resistance to electrostatic discharge and a longer lifespan. With this added feature, your device is built to withstand more rigorous environments.
5.PC Control and Connectivity: Connect the tinySA to your PC via USB, transforming it into a PC-controlled spectrum analyzer. The USB interface supports the Serial over USB (CDC) protocol, enabling the use of various commands through the serial interface. These commands allow you to perform measurements or update internal settings. When connected to a Windows PC, the device automatically installs the necessary Windows drivers, while Linux users can enjoy built-in kernel support. Take full control of your analysis and maximize efficiency with PC connectivity.

For for tinySA is a portable spectrum analyzer developed by Dutch developer Erik Kaashoek. After we launched NanoVNA, the community has always hoped to have a portable spectrum analyzer similar to it, and now we have manufactured it using the same volume and cost as NanoVNA.
Attention!!!
Input signals exceeding the damaged power (20dBm (100mW)) will damage for tinySA. Please connect a suitable attenuator when testing the transmitter!
For tinySA is not an SDR receiver and does not provide any receive demodulation function!
For tinySA is not a frequency scanner and does not provide tracking source output. If you need a frequency scanning function, please use NanoVNA!
