Record Constant On
DS2000A provides record “Open” (record constant on) mode for waveform record.
When this mode is enabled, the oscilloscope records the waveform continuously
according to the current memory depth. The length of the waveform recorded is
limited by the memory depth and the waveform data recorded before will be
overwritten by the waveform currently recorded. In this mode, the other oscilloscope
operations (except
Pass/Fail Test as well as Acquisition Mode, Sample Mode,
Sample Rate and Memory Depth in the sample system setting and Time Base
Mode in the horizontal system setting) are not affected.
Press Utility Record Mode and use to select “Open”. At this point, the
waveform record key at the front panel turns red and the oscilloscope records
the waveform continuously according to the current memory depth. The oscilloscope
stops recording until users press RUN/STOP and at this point, users can play back
or analyze the waveform.
In constant on mode, the oscilloscope can capture the accidental abnormal signals
during the adjustment. Following is an application example of the record constant on
mode. Use DS2000A (CH1) to observe a pulse which might contain runt pulses.
1. Connect the pulse under test to CH1 of the oscilloscope. Adjust the oscilloscope
to make it trigger stably.
