6 Upgrade Option U01
The capabilities of the instrument can be enhanced by installing the upgrade option U01 which
adds additional firmware to the instrument.
Option U01 can be downloaded from the Aim-TTi website and can be installed by the user
without any requirement to return the instrument to its supplier. Activation of the upgrade is
achieved via an activation code which can be purchased from the Aim-TTi website, or from our
distributors and agents across the world.
6.1 Additional Functions from Option U01
The following facilities will be incorporated. Additional facilities may also have been added -
see the Aim-TTi website for up to date information.
6.1.1 Logging of Values, Traces or Screens
The Logging function enables results to be saved into log files in response to a timer or to a
trigger event. Individual amplitude values, complete traces, or full screen images can be saved.
See section 4.8.1 for more information.
6.1.2 Triggering
The triggering function enables sweeps or logging to be triggered in response to an internal or
external trigger event. The internal trigger event can be generated by the Limits function.
See section 7.4 for more information.
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-Manager.
6.1.7 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 for more information.
