PC based Oscilloscopes

This product search is based on the need to analyze the TTL bit stream coming out of the PRC-126 US Army Squad Radio to determine the protocol.
This should allow the construction of a Cloning Device, Lap Top cahnnel frequency progrmmer, and maybe a retransmission adapter.  The Pico Technology ADC10 dongle worked well for the slow data rate.
