Compact N2PK VNA with Graphic display

The VNA uses small reflection bridge ZEDC-10-2B from Mini Circuits. To fit the VNA into small enclosure and make it real handheld I cut off a second detector. 3600 mA/H Li-Ion battery supplies 12V.   DC/DC converter used to step down voltage to 5V.

Graphic interface controlled by PIC32MX460F512L from Microchip. Code is written in C language under MPLAB IDE Microchip Graphic library used to create the interface.

Please let me know if you have any questions.
