Recording Scope
Recording Scope can be Spooled Recording or Conventional Single-Buffer Recording.
Select the radio button to choose one or the other.
Spooled Recording
Spooled recording displays the trace in real-time during recording.
Spooled recording records the trace on the hard disk drive, not the analyzer hardware.
Conventional single-buffer recording has a limit of 1GB or 2GB in the analyzer hardware.
For spooled recording, recording size has the limit specified in the Maximum Disk Usage
field or Recording Size Limits field. If you do not specify a limit, available recording size
is the free disk space available on your hard drive.
Spooling divides recorded data into 350-MB chunks. If you enable the Maximum Disk
Usage option, after recording size passes the limit you specify, the software deletes the
oldest chunk to allow disk space for the most recently recorded chunk.
For spooled recording, you can indicate both or either of:
• Max Disk Usage: Enter the number of gigabytes (GB), as a whole number
(no decimal point). Default is 5 GB.
• Recording Size Limits: Select one of:
• Record for a selected number of days, hours, minutes, and seconds.
Default is 0 days.
• Record a number of megabytes (MB). Enter a whole number, with no
decimal point. Default is 120,000 MB.
• Until triggered plus a selected number of days, hours, minutes, and
seconds. Default is 0 days.
• Until triggered plus a number of megabytes (MB). Enter a whole
number, with no decimal point. Default is 120,000 MB.
Conventional Single-Buffer Recording
For single-buffer recording, you can set buffer size and trigger position.
Buffer Size
The program records the entire trace and stores it in the analyzer buffer before uploading
it to the host PC. The buffer size determines the maximum size of a recording.
Use the Buffer Size slide bar to set the recording buffer size from 1.6 MB to 2048 MB
(Figure 12.2).
Figure 12.2 Recording Options: Buffer Size Slider
Note: With a regular license, maximum recording buffer size is 1024 MB. You need
a unit with a 2-GB license to have a maximum recording buffer size of
2048 MB.
