6.1.3 Limit Lines and Patterns
Limit lines and patterns can be shown on the display, and compared with the trace. They can
be used to trigger a logging event, generate an audible warnings or output a trigger pulse.
Limit lines are simple straight lines whereas limit patterns are frequency dependent amplitude
limits that are stored as files. Two limits can be used simultaneously.
See section 7.6 for more information.
6.1.4 Level Offsets
The level offset function enables the level values for the graticule and markers to be corrected
for external attenuation or gain. Compensation can also be made for signals coming from a
75
source.
6.1.5 Compensation Tables
Compensation tables are lists of amplitude versus frequency which enable frequency related
amplitude variations from antennae or transducers to be compensated for within the spectrum
analyzer. Compensation tables are stored as files. See section 7.5.2 for more information.
6.1.6 View on PC
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 PC
software. See section 13 (Appendix A) for more information.
6.1.7 Custom Presets
Custom Presets enables multiple presets (set-ups) to be saved/recalled just by entering a
number. See section 7.2.5.
6.1.8 PSA-Manager Software
PSA-Manager is a Windows based software application which is used in conjunction with the
instrument. It provides the capability for displaying and printing Traces and Screen Images,
display and analysis of Log files, and creation of Limit Patterns and Compensation Tables.
See section 13 (Appendix A) for more information.
