Portable vector network analyzer

The Thinkstar NanoVNA covers 50 kHz to 6.3 GHz in a pocket-sized unit with a 4.0 inch 480 x 320 touchscreen. It measures S11 reflection and S21 transmission using a single mixer and internal RF switches. A 2000 mAh battery powers field sessions and a MicroSD slot stores data.

Single-mixer architecture and storage limits

One mixer handles both S-parameter ports through electronic switching, which keeps the device small but means simultaneous two-port measurement is not possible. MicroSD cards must be 32 GB or smaller and formatted FAT or FAT32; larger or differently formatted cards will not work. The SPI interface limits write speed compared with SDIO.

Touchscreen operation and connector layout

The resistive touchscreen responds to stylus or gloved fingers, useful for outdoor antenna work. SMA ports sit on the top edge for direct cable attachment without adapters. MicroSD and USB-C sit on the side, leaving the bottom clear for a bench stand or magnetic mount. No protective case is included.

Questions about this item

Which frequency range should I choose between the 50 kHz to 6.3 GHz model and earlier 1.5 GHz or 3 GHz versions?

The 50 kHz to 6.3 GHz range covers amateur radio, IoT, 5.8 GHz Wi-Fi and 5.8 GHz video links, while the older 1.5 GHz and 3 GHz models stop well below those frequencies.

What does the 6.3 GHz upper limit mean when I connect an antenna or filter?

You can measure S11 return loss, S21 insertion loss, SWR, phase, cable attenuation and amplifier gain up to 6.3 GHz, plus TDR and DTF distance-to-fault data via IFFT.

What does the MicroSD slot support and what capacity limit applies?

The slot accepts MicroSD cards up to 32 GB formatted FAT or FAT32 in SPI mode for saving SNP data files or BMP screenshots.
