leads to a series of menus used to deline limits or specifications
with which to compare a test device. Refer to Limit Lines and
Limit Testing.
turns limit testing on or off. When limit testing is on, the data
is compared with the defined limits at each measured point.
Limit tests occur at the end of each sweep, whenever the data
is updated, when formatted data is changed, and when limit
testing is hrst turned on.
Limit testing is available for both magnitude and phase values
in Cartesian formats. In polar and Smith chart formats, the
value tested depends on the marker mode and is the magnitude
or the fist value in a complex pair The message "NO LIMIT
LINES DISPLAYED" is displayed in polar and Smith chart
formats if limit lines are turned on.
Five indications of pass or fail status are provided when limit
testing is on. A PASS or FAIL message is displayed at the right
of the LCD. The trace vector leading to any measured point that
is out of limits is set to red at the end of every limit test, both
on a displayed plot and a hard copy plot. The limit fail beeper
sounds if it is turned on. In a listing of values using the copy
menu, an asterisk * is shown next to any measured point that is
out of limits. A bit is set in the HP-IB status byte.
puts the result of a limit test into the display title.
leads to the limit type menu, where one of three segment types
can be selected.
activates a linear frequency sweep displayed on a standard
preset sweep type.
displays the linear magnitude format. This is a Cartesian format
used for unitless measurements such as reflection coefficient
magnitude p or transmission coefficient magnitude 7, and for
linear measurement units. It is used for display of conversion
parameters and time domain transform data.
displays a readout of the linear magnitude and the phase of the
active marker. Marker magnitude values are expressed in units;
phase is expressed in degrees.
provides access to the Line/Match Menu for TRL/LRM
calibration.
selects the line type for the data trace plot. The default line
type is 7, which is a solid unbroken line.
selects the line type for the memory trace plot. The default line
type is 7.
