It would appear Miniware didn’t do enough testing, and it’s impossible to distinguish a good signal from a faulty one when using a LA104 – arguably, the primary function of a logic analyzer.

The people at CWAV loaned me one of the USBee RX pods that combines an 18-input logic analyzer, 8-output logic pattern/signal generator, and 2-channel scope in a small package that communicates with a ...

Logic analysis is a common tool in FPGA development. If you use Altera, they have Signal Tap available that lets you build a simple logic analyzer into the FPGA that talks back to your PC.
