摘要： A combined logic timing and state analyzer comprises an internally clocked, timing analyzer section receiving a first set of logic signals, and an externally clocked, state analyzer section receiving a second set of logic signals. The timing analyzer section samples the first set of logic signals, as well as the external clock signal associated with the second set of logic signals, at a rate determined by the internal clock pulses and stores the samples in a first set of memories. The state analyzer section samples the second set of logic signals at a rate determined by the external clock pulses and stores the samples in a second set of memories. Data introduction into the memories terminates when they are triggered, as in the event of a malfunction of the system being investigated. The logic analyzer further includes a display circuit for repetitively reading out the first and the second sets of memories and for causing a display device to visually present the output data of the first memory set in the form of a timing diagram and the output data of the second memory set in the form of a state table. The time relationship between the two display formats can be readily ascertained since the timing diagram includes a waveform, or other visual representations, indicative of the external clock pulses used for sampling the second set of logic signals.
