turns limit testing on or off. When limit testing is on, the data
is compared with the defmed 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 first 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 first 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
shown next to any measured point that is out of limits A bit is
set in the HP-IB status byte.

leads to the limit type menu, where one of three segment types
can be selected.
activates a linear frequency sweep displayed on a standard
graticule with ten equal horizontal divisions This is the default
preset sweep type.
displays the linear magnitude format. This is a Cartesian format
used for tmitless measurements such as reflection coefficient
magnitude p or transmission coefllcient 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.
provides a tabular listing of all the measured data points and
their current values, together with limit information if it is
turned on. At the same time, the screen menu is presented, to
enable hard copy listings and access new pages of the table. 30
lines of data are listed on each page, and the number of pages is
determined by the number of measurement points specified in
the stimulus menu.
