Editing Downloading offline scope capture in Granity

[[Granity]] version 1.12 and later allows downloading capture graphs that were recorded offline (i.e. when drive was not connected to granity). This may be useful when diagnosing a problem that occurs rarely or is hard to reproduce under Granity connection.

Usage:
# Connect to a drive
# Setup a desired capture. Configure following values:
## Choose a desired trigger source such as ''Capture on setpoint change'' or ''Capture on fault''
## Choose sample rate [[TSR]]
## Choose capture signals to be recorded
## Untick "Continuously repeating capture"
# Press Start capture
# Disconnect from drive and wait the capture to occur
# Connect back to device. Don't change any capture settings, or restore them to same than in step 2 if changed or software restarted) 
# Press keyboard hotkey Alt+W to download and view the previously recorded offline capture

== Notes & limitations ==
* Offline capture will be preserved only when drive logic power stays on. If device is powered off, no capture will be available for download.
* If no capture is in device memory, or it has been captured with different settings than the ones active in Granity UI, the downloaded graphs may be corrupt/invalid

== Example use ==
See [[Troubleshooting position control faults]]. You may apply offline capture to catch faults described in that page.
