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 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
software - see section 6.1.7.
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.
7.8 View on PC
The View on PC function is only available when the upgrade option U01 is fitted (see section 6).
A description of the menu keys used to control the function is given in section 4.10.3.1.
View on PC places the instrument into a special mode in which the graphics of the display are
sent to a PC via USB. The screen can then be viewed at any size using PSA-View software.
The message View on PC is displayed in blue at the top right of the graticule area.
When in this mode, screen update rate may be reduced.
