The pattern generation device includes: a main memory for correlating a scan pattern data block containing pattern data for performing a scan test to a scan sequence data block containing an instruction indicating the sequence for supplying data of the scan pattern data block to the electronic device and storing them; and a data spreading section for executing the instruction in the scan sequence data block so as to spread pattern data in the corresponding scan pattern data block, thereby generating a test pattern.
A pattern generator includes: a main memory for storing a plurality of sequence data blocks for generating a test pattern; a first sequence cache memory for successively storing the sequence data blocks; a second sequence cache memory, a data spread section for successively executing the sequence data blocks stored in the first cache memory and generating a test pattern; and pre-read means.
A semiconductor test device, comprising a test device body generating a test pattern provided to a semiconductor device, a test head coming into contact with the semiconductor device to provide the test pattern generated by the test device body to the semiconductor device, a cable receiving the test pattern from the test device body and sending the test pattern to the test head, and a movable support part holding the cable and moving in the direction that releases a tension in the cable when the tension is produced in the cable.
A testing apparatus for testing a device to be tested is provided with a pattern generating section for generating a test pattern having a test signal to be supplied to the device to be tested; a timing signal generating section for generating a timing signal indicating timing for supplying the test signal to the device to be tested; a digital filter which filters the test pattern and outputs a jitter control signal indicating jitter corresponding to the test pattern; a jitter applying section for applying jitter to the timing signal by delaying the timing signal corresponding to the jitter control signal; and a waveform shaping section for generating a test signal by shaping the test pattern by having the timing signal to which the jitter is applied as reference.
The device includes: modulation means (103) for generating a test pattern containing at least a first recording mark length; recording pulse string conversion means (104) for converting the generated test pattern into a recording pulse string containing trial write recording pulses havingdifferent time widths corresponding to at least the first recording mark length; light emission means (106); reproduction signal processing means (109) for holding as a first signal index characteristic, the relationship between a first signal index acquired according to the reproduction signal obtained from a predetermined region and the recording power; and recording condition calculation means (111) for obtaining a desired time width of a recording pulse of the first recording mark length.
