Title: Cross talk measuring instrument
Inventor: KAWAGUCHI MORIYUKI
IPC: H04N5/782
Filed: 1985-12-04
Abstract: PURPOSE:To easily measure cross talks between adjacent tracks, by measuring a cross talk component from the signal level of frequencies to be measured in the reproduced signals of a tape. CONSTITUTION:A-channel head 14 and B-channel head 16 which constitute a pair of magnetic heads at an angular interval of 180 deg. are slid on a tape and the signals of frequencies (5MHz, 1.5MHz, and 750KHz) to be measured are recorded at the rate of 1 field to 9 fields which are an odd numbers of fields above 7 fields. Then the signals of a frequency of 4.5MHz which is distinguishable from the signals of the frequencies to be measured are recorded in the other tracks of the 9 fields. Thus the patterns of the recording tracks are formed. The patterns are alternately traced by the A- and B-channel heads 14 and 16 and the selected channel and distribution of signal components of the frequencies to be observed are observed by means of a spectrum analyzer 23 from the reproduced signals of the heads 14 and 16. Therefore, each cross talk or A- and B-channels can be measured with the same recording pattern.
