Waving Measurement Procedures
1. Press “SPACE” key for make the Peak Hold during 30 seconds when linearity is displayed.
2. After finish the Peak Hold, press “SHIFT” and “ } “ key simultaneously on the Key Board, then display the
numerical values of “Linearity” and “Waving” on left lower portion of screen. And confirm the numerical values
are in the specification. Also confirm the range of waving waveform is same quantity from entrance side to
exit side. If the “Linearity” and “Waving” are out of specification and it caused by not enough limit of entrance
or exit side of envelope, then adjust height of S1 and T1 post.
3. After this measurement is finished, press the ESC key to return to the main menu.
Information : How to save the LISTA Data
The LISTA software can be saved linearity waveform and measurement value of linearity and waving as one file
data to PC.
1. Basically this operation should be performed after linearity and waving measurement finished.
2. Select the item “<3> Data Save/Load” on the LISTA main menu, and select the item “<1> Save”.
3. The linearity waveform as Peak Hold displayed on the screen, and after appeared message “File Name?” on
the screen. Then entry the File Name less than 8 letters, and after appeared message “Comment?” on the
screen. Then entry the Comment less than 20 letters. As comment, entry the Serial Number, Model Number,
Head Rotation Hours etc, for use management of linearity data of each VTR and Camera Recorder.
4. After completion of saving, select the item “<2> Load” of the item ”<3> Data Save/Load”, then appear the
saved File Name on the screen. And select it previous saved file for confirm the waveform and numerical
value displayed correctly. By press “SHIFT” and “ } “ key simultaneously on the Key Board, then display the
numerical values of “Linearity” and “Waving” on left lower portion of screen.
