Saving a Captured Waveform Record
1.
Select "Export-Oscillographics" from the File
Menu.
2.
Select the record you want to save and click
“Save To File”. See Figure 10-6.
3.
Type the path and filename you want for the
record and click “Save”.
The Waveform Capture feature also allows the user to choose certain data recording options. In addition to the Trigger
Sources, there are four other settings in the Waveform Capture folder. They are Record Type, Trigger Position, Single-
Shot Mode, and Append Record Mode. The factory default condition has Oscillographic Data Acquisition set to “ON”.
Record Type:
There are four types of records, “0”, “1”, “2”,and “3”. Selecting “0” will yield eight records of eight cycles each. “1”
gives four records of sixteen cycles each, “2” gives two records of 32 cycles each, and “3” gives one 64 cycle
record.
Trigger Position Setting:
This setting is the amount of pre-event data that will be recorded with each oscillographic record (in quarter
cycles). For example, if you wish to have one cycle (4 quarter cycles) of pre-trigger data recorded, choose “4” for
the Trigger Position setting.
Single-Shot Mode:
Single-Shot Mode can either be “ON” or “OFF”. When it is “OFF”, the oldest oscillographic record will be over
written when the buffer becomes
filled. When “ON”, oscillograpic
records will be recorded until the
buffer is filled to capacity. The buffer
size is determined by the Record
Type setting chosen (0, 1 ,2, or 3).
After the buffer is filled, data
acquisition will be stopped. If more
data recording is desired, the “Start
Oscillographic Data Acquisition”
command must be selected from the
Control Menu in WinECP.
Append Record Mode:
Append Record Mode can either be “ON” or “OFF”. When it is “ON”, a new record will be generated if a trigger
occurs while a previous oscillographic record is being recorded. Append Record mode will only work when the
Record Type setting is either 1, 2, or 3.
NOTE: Download the captured waveform records to a file before changing any Waveform Capture setings. Changing
settings may lose waveform records. From the factory, Waveform Capture is running, all trigger sources are set
to “NO”. The proper sources must be set to “YES” for the capturing of Waveforms.
