UPGRADED NANOVNA-H: NanoVNA-H with extra 9 SMA calibrations and connectors, you will get SMA simple calibration kit OPEN x2, SHORT x2, LOAD x2, SMA female to female connector x2, SMA male to male connector x1. Added SD card port, can save the measurement data or screenshots at any time. ABS material case can protect the nanovna from damage during transportation and is dust-proof WIDE FREQUENCY RANGE: The improved frequency algorithm can use the odd harmonic extension of si5351 to support the measurement frequency up to 1.5GHz. The 50K-300MHz frequency range of the si5351 direct output provides 70dB dynamic, The extended 300M-900MHz band provides 60dB of dynamics, and the 900M-1.5GHz band is 40dB of dynamics MULTIPLE FUNCTIONS: The default firmware main function is used for antenna performance measurement and lots of measurement types. The TX/RX can measure the complete S11 and S21 parameters. If you need to obtain S12 and S22, you need to manually replace the transceiver port wiring. Designed a practical and simple control application on PC, you can download (SNP) files for radio design and simulation software. Support time domain analysis function (TDR) PORTABLE SIZE & EASY TO READ: The portable size VNA analyzer (2.1in x 3.4in x 0.4in) come with a nice box which have 2.8inch TFT display(resolution 320x240)can be taken everywhere and the screen is more larger and easier to read Colour: Black material: metal Package Contents: 1 set spectrum analyzer Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
