Waving Measurement Procedures
1. Press "SPACE" key to perform the Peak Hold in 30 seconds when linearity is displayed.
2. After finishing the Peak Hold, press "SHIFT" and " } " key simultaneously on the Key Board, then the numerical
values of "Linearity" and "Waving" is displayed on left lower portion of screen. And confirm the numerical values
are in the specification. Also confirm the waving is same level from entrance side to exit side. If the "Linearity"
and "Waving" are out of specification and also it caused by insufficient limit of entrance or exit side of envelope,
adjust height of S1 and T1 post.
3. After this measurement is finished, press the ESC key to return to the main menu.
Confirm this value
Information : How to save the LISTA Data
Linearity waveform data, measurement value and waving value can be saved as one file data to PC.
1. Basically this operation should be performed after linearity and waving measurement is 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 is displayed on the screen, and message "File Name?" appears on the
screen. Then enter the File Name less than 8 letters. Nextly enter the Serial No. and press enter, then message
