Portsdown Test Equipment

The Portsdown 4 includes some very useful test equipment features including 6GHz RF signal generator, Noise figure meter, frequency sweeper and noise power meter.

Most of these facilities can be run from a basic RPi running the free Portsdown software.

Constructors can build their own SD Cards using the install file on GitHub BATC Portsdown 4 GitHub Page. Pre-programmed SD Cards are also available from the BATC Shop - https://batc.org.uk/shop/portsdown-transmitter-pre-programmed-sd-card/
