upward under the right side of the last waveform. There is also a time scale beside the arrow. "0 s" is used to mark the
moment when waveforms are frozen. With waveforms moving right, this time mark will turn into "-1 s, -2 s, -3 s…".
6.4 Recording Frozen Waveform
In the Freeze status, you may output displayed frozen waveforms via the recorder. Maximum 2 waveforms can be
output at one time. On the FREEZE menu, the pull-down lists of both "WAVE 1" and "WAVE 2" give you all names of
frozen waveforms on the screen, from which you may select two waveforms. Select the "REC" option on the FREEZE
menu to output parameters generated upon the freezing moment and the two selected frozen waveforms. If one of the
two selected waveforms is set off or not available, only parameters and the other waveform are recorded. If these two
selected waveforms are all set off or not available, only parameters are recorded. As for the function of recording frozen
waveforms, you can only record the waveforms displayed upon the freezing moment. The recording time length is the
same as the length of the waveform displayed on the screen. For example, if the speed of a waveform is relatively fast,
then it needs shorter time to record it. When recording frozen waveforms, the system is still in the Freeze status. After
completion of this recording, if required, you may select another waveform to be output, and select "REC" option again
to record until the all necessary waveforms are recorded. You may also record frozen waveforms by pressing the
"REC/STOP" button on the front panel. If selecting "REC" option without installing a recorder, the system will prompt
"RECORDER ERROR" in the status bar. For more detailed information about recording, please refer to the chapter
