symbolic forms. See Section 7.3 Setup Operating Parameters (SOPRM) on
page 259 for details regarding the threshold parameters and TCF values.
4.1.4 @ – Display/Change Current Major
Mode
This command provides developers with a simple way of switching modes
enabling on–the–fly testing of code. The top level RVP900 operating
modes are described in the documentation of the SOPRM command word
#9. This question allows you to use the mode that has been selected by that
command, or to force the use of a particular mode.
4.2 View/Modify Dialogs
The M menu may be used to view, and optionally to modify, all of the
current settings. The current value of each parameter is displayed on the
screen, and the TTY pauses for input at the end of the line. Pressing
Return advances to the next parameter, leaving the present one
unchanged. You may also type U to move back up in the list, and Q to exit
from the list at any time.
Typing a numeric or YES/NO response (as appropriate to the parameter)
changes the parameter's value, and displays the line again with the new
value. All numbers are entered in base ten, and may include a decimal point
and minus sign. In some cases, several parameters are displayed on one
line, in which case, as many parameters are changed as new values are
entered. In all cases, the numbers are checked to be within reasonable
bounds, and an error message (listing those bounds) is displayed if the
limits are exceeded.
The M menu provides access to a large number of configuration settings.
As a result, all of the M menu commands begin with the letter "M" and are
followed by a lower case letter, which represents a subcategory, that is, Mb
(Burst Pulse and AFC), Mc (Overall Configuration), Mf (Clutter Filters),
Mp (Processing Options), Mt (Triggers and Timing), Mz (Transmissions
and Modulations), M+ (Debug Options). The ?? command by itself prints
the entire set of questions so that you can make a hard copy.
NOTE
Changes to the settings (generally) do not take effect until after the Q
command is typed, at which point the RVP900 exits the local TTY menu
and resumes its normal processing operations.
