Table 34 Plot Command Conventions
Convention Description
Display commands Most plot commands support subcommands that alter the appearance of the display,
for example, zoom, stretch, and so on.
These subcommands make no changes to the working RVP900 calibrations.
Display settings are stored in nonvolatile RAM, like the other setup parameters.
Previous display settings are restored when you restart each plot command.
If the initial list of subcommands disappears o the top, type ? to force a reprint.
Exit To exit the plot command and return to the TTY main menu, type Q or ESC.
All other keys return the plot command to its normal live updating, but the key is
otherwise discarded (for example, subcommand keys are not executed while exiting
from single step mode).
Lower case
commands
Upper case
commands
Most commands have a lowercase and an uppercase version.
If a lowercase command does something, then its uppercase version does the same
thing, but even more so (or in reverse).
For example, if the w subcommand widens something by a little bit, the W widens it a
lot. This simple convention reduces the number of
dierent subcommand keys that are
needed, and makes the interface easier to memorize.
Single Step mode By default, the graphical display and TTY status lines are updated with fresh data
several times per second.
If you wish to freeze a plot for further analysis or comparison enter Single Step mode
by typing: ." (period)
This causes the display and TTY status lines to freeze in their present state, and prints
the message "Paused..." is printed.
To move to the next data update, retype ." (period). The plot and printout remain
frozen at the next data update.
Scrolling The TTY screen scrolls upward each time a new subcommand is executed to show a
history of information lines and command activity. Press ENTER to scroll the display up
at any time.
% Press % to toggle between the IF input SMA connectors on the IFDR.
