See Data Logger Trigger (Y06).
Single (0):
If Data Logger Arm (Y11) is set to 1 the scope starts to acquire pre-trigger data (i.e. enough data to provide information for the pre-trigger period) and
Data Logger Data Not Ready (Y12) is set to 1. The scope can then be triggered on the next trigger event (i.e. a rising edge on the trigger input of the
main scope block). Note that the scope can only be triggered once the required amount of pre-trigger data has been sampled. Failure to do this will
result in the scope function not triggering correctly. When the trigger event occurs Data Logger Arm (Y11) is set to 0, and when the post-trigger data
has been stored Data Logger Data Not Ready (Y12) is set to 0. If Autosave Mode (Y17) is non-zero, the data in the scope trace buffer is saved to a
non-volatile media card fitted in the drive. When the save is complete (or data cannot be saved, i.e. no card installed or no space left) the scope is
ready again to receive data. If Data Logger Arm (Y11) is set to 1 the scope will start to acquire data again.
It is possible to read scope files via comms or into an option module. However, scope file transfer can only be initiated when Data Logger Arm (Y10)
= 0, Data Logger Data Not Ready (Y12) = 0, Data Logger Saving Data (Y13) = 0 and at least one trace has been set up. While the file transfer is in
progress Data Logger Saving Data (Y13) is set to 1.
The scope system is reset under any of the following conditions:
1. At power-up.
2. If the drive is reset when Data Logger Trace 1 Source (Y02) to Data Logger Trace 4 Source (Y05) have been modified.
3. The drive mode is changed.
4. If Data Logging Mode (Y10), Data Logger Sample Time (Y14) or Data Logger Trigger Delay (Y15) are modified.
When the scope is reset Data Logger Arm (Y11) is reset to 0 and the trace data is all cleared to 0.
Normal (1):
The scope operates in the same way as single mode except that Data Logger Arm (Y11) is automatically set back to 1 after a time delay of 1s once
the post-trigger data has been acquired, and the scope dat
a has been saved to a n
on-volatile media card if Autosave Mode (Y17) > 0.
