measures the absolute power amplitude at input B.
calculates and displays the complex ratio of input B to input R.
deletes the last character entered.
sets the background intensity of the LCD as a percent of white.
The factory-set default
value
is stored in non-volatile memory.
(Option 010 only) sets the time-domain
bandpass
mode.
toggles an annunciator which sounds to indicate completion of
certain operations such as calibration or instrument state save.
turns the limit fail beeper on or off. When limit testing is on
and the fail beeper is on, a beep is sounded each time a limit
test is performed and a failure detected. The limit fail beeper is
independent of the warning beeper and the operation complete
beeper.
toggles the warning annunciator. When the annunciator is on it
sounds a warning when a cautionary message is displayed.
switches off the analyzer’s display. This feature may be helpful
in prolonging the life of the LCD in applications where the
analyzer is left unattended (such as in an automated test
system). Pressing any front panel key will restore the default
display operation.
adjusts the brightness of the color being modified. See Adjusting
Color for an explanation of using this softkey for color
modification of display attributes.

standard in a calibration kit, which is the constant term of the
cubic polynomial and is scaled by 10-15.
is used to enter the Cl term, expressed in
F/Hz
