Freezing Waveforms
7-4
7.4 Waveform Recall
1. In the frozen mode, select the RECALL option in the FROZEN menu, and the
option name changes to L-RIGHT.
2. Rotate the control knob clockwise, and the frozen waveforms move to the right.
At the lower right corner of the lowest waveform is an arrow pointing upward.
The time is indicated below the arrow. The indication "0S" is used to mark the
moment when the waveforms were frozen.
3. With the waveforms move to the right, the time mark, in turn, changes to -1S,
-2S, -3S…
4. The time mark is applied to all waveforms displayed on the screen.
5. Rotate the control knob anticlockwise, and the waveforms move to the left.
7.5 Recording Frozen Waveforms
1. Select WAVE 1 and WAVE 2.
2. Select the REC option, and the recorder prints out the selected frozen
waveforms and the parameters measured at the moment when the waveforms
were frozen.
3. If OFF is selected from the WAVE 1 or WAVE 2 options, the recorder will
merely print out one waveform and the parameters measured at the moment
when the waveforms were frozen.
4. If OFF is selected from both the WAVE 1 and WAVE 2 options, the recorder
will not print out any waveform and will merely print out the parameters
measured at the moment when the waveforms were frozen.
5. The recording time length is identical to that of the waveforms displayed on the
screen. If a waveform is of faster sweep speed, its recording time is shorter.
6. During waveform recording, the monitor is still in frozen mode.
7. When the recording completes, you can select to record other waveforms.
8. If the recorder is not installed, selecting the REC option or pressing the
RECORD key triggers the "Recorder does not exit" message, which is
displayed in the prompt information area.
