Keywords: base band I/Q  signal-analysis measurements  probing techniques 

[Summary of tips] Designing and testing communications systems with analogue base band I/Q (BBIQ) circuits can be a challenge for RF engineers. The goal is to make traditional signal-analysis measurements in the spectral and time domains, along with digital-modulation analysis. However, compared to IF and RF, BBIQ presents unique connection chal......
