To achieve the fastest possible logging use Continuous trigger - see section 7.7.6.
7.7.4 Logging from External Trigger
The logging function can be set via the Log Trigger key to save entries on either a positive or
negative going edge applied to the Trigger socket - see section 7.4.1.
The data that is logged will relate to the sweep that was in progress when the trigger signal
occurred.
7.7.5 Logging from Amplitude Limits
The logging function can be set via the Log Trigger key to save entries when a signal is
generated by the Amplitude Limits Comparator. The data that is logged will relate to the sweep
that was in progress when the limit condition occurred.
The Limits function must be set to have a potentially valid condition. See section 7.6 for an
explanation of the Limits function.
7.7.6 Logging Every Sweep (Continuous)
The logging function can be set via the Log Trigger key to save entries continuously, i.e. after
every sweep. The actual speed will depend upon the sweep rate and the type of data being
logged. The fastest possible logging rate is about two per second.
7.7.7 File Sizes and Maximum Logging Times
Logging files can vary in size from a few kB to more than 100MB depending upon the number
of entries and the type of data being logged.
Although the filing system allows up to 999 .LOG files to be stored, the practical number may be
limited by the internal memory size (approximately 1.8GB). Where large files are being created,
care must be taken not to overflow the memory. Memory space can be restored by copying
files to a Flash drive or directly to a PC, and then deleting them on the instrument.
The instrument has the potential to log over very long periods. Where it is required to log for a
period close to or exceeding the battery life, the instrument must be operated from external AC
power.
In the event of the memory becoming full or the power being lost, the current logging file will be
automatically closed.
7.7.8 Viewing and Analyzing Logging Files
The instrument has no capability for viewing the contents of a logging file. Instead, the file must
be copied to a Windows based PC where the file can be viewed and analyzed using the PSA
Manager software - see section 6.1.8.
Log files have the extension .LOG and are located in the folder named LOGS. Up to 999
logging files can be stored within the memory of the instrument. Files can be transferred using
either a USB Flash drive, or by direct connection to the USB port of a PC.
See section 5 for an explanation of copying and transferring files.
