Tester for collision-detect circuitry

摘要: A tester for the collision detector of a transceiver multiple access data communications network using carrier-sense detection controlling to network. squelch circuit is employed in transceiver's transmitter enabling and disabling output. An end-of-transmission monitors detect termination transmission. Upon transmission, simulator supplies receiver signal predetermined amplitude duration, simulate input gets when actually occurs. If working properly, it signals host (i.e., computer, terminal, etc). does not receive at appointed time, knows that either or working.
