ABSTRACT:
A transmitter test circuit (40) for serially transmitting multiple packets of digitized analog signals comprises translation circuitry in the form of analog-to-digital interface (142) that translates an analog signal into a digital representation of the analog signal. The digital representations comprise a plurality of binary bit positions. A shift register (200) receives and outputs the digital representations. The load/shift control bus operates between the shift register or PSA/sample register (200) and a serializer circuit (204) for loading the digital representations into the shift register (200). Output circuitry shifts the digital representations out of the shift register to an intermediate integrated circuit (43) and on to a test bus controller (44). Test bus controller (44) includes input/output circuitry (61), a memory (59), a processor (63) registers (45 and 47) and a test port controller (71). Test bus controller (44) may output to a plurality of external test port devices.
