ABSTRACT:
An interface signal gate and received interface and flaw signals are displayed by a cathode-ray tube on respective sweeps from a first sweep generator having coinciding baselines. The gate as displayed is adjustable in height, width and position to enable the operator to select the desired interface signal. When adjusted so that the height of the interface signal exceeds the gate height, a trigger signal is produced which controls a second sweep generator to display flaw signals occurring after the interface signal. Sweeps from the second generator are displaced from the sweeps of the first generator, as displayed, and alternately display received signals and a flaw signal gate which is adjustable in height, width and position to select flaw signals above an adjustable threshold level for indication, etc. Received signals and interface and flaw signal gates are continually displayed on predetermined sweeps from the two sweep generators. A first sweep and interface gate are produced by each transmitted pulse, and a second sweep and flaw signal gate are produced by each trigger signal, and respective sweeps and gates and the received signals are blocked from the CRT during other than the predetermined sweeps during which the received signals and gates are respectively displayed. Echo checking is provided in which a sub-multiple of the PRF of the transmitted pulses is employed.
