that uses this class.
REV MATCH (Specify Class). specifies which standards are in the reverse match class in the calibration kit.
REV MATCH THRU. is used to enter the standard numbers for the reverse match (thru) calibration. (For default kits,
this is the thru.)
REV TRANS (Label Class). lets you enter a label for the reverse transmission class. The label appears during a
calibration that uses this class.
REV TRANS (Specify Class). specifies which standards are in the reverse transmission class in the calibration kit.
REV TRANS THRU. is used to enter the standard numbers for the reverse transmission (thru) calibration. (For default
kits, this is the thru.)
REVERSE: OPENS. provides access to the menu for selecting an open calibration type when the cal kit defines more than
one open standard.
RIGHT LOWER. draws a quarter-page plot in the lower right quadrant of the page.
RIGHT UPPER. draws a quarter-page plot in the upper right quadrant of the page.
RIPL LIMIT on OFF. displays lines that represent the ripple limits when the ripple test is set to ON.
RIPL TEST on OFF. turns ripple testing on or off. When ripple testing is on, the analyzer sets the lower ripple limit line at
the lowest amplitude point within the frequency band and sets the upper limit line at the user-specified amplitude
above. If the trace data remains at or below the upper limit line, that portion of the ripple test passes. If the trace data
rises above the upper limit line within the frequency band, the test fails. Data within each frequency band is compared
with the defined ripple limit of the band. The ripple test checks each frequency band using this method. A maximum of
12 frequency bands can be tested on each channel. These bands may overlap in frequency. If all of the channel’s
frequency bands pass the ripple test, the analyzer displays a pass message. If the test passed, a message is displayed in
orange text in the upper right portion of the LCD. An example of this message is: RIPL1 PASS, where the “1” indicates
the channel where the ripple test is performed. If the ripple test does not pass, a fail message is displayed in red text.
An example of this message is RIPL1 FAIL.
RIPL VALUE [ ]. displays the ripple value of the selected frequency band. The ripple value can be displayed in two ways
or turned off. Selecting OFF removes the displayed ripple value from the display. Selecting ABSOLUTE or MARGIN
displays the ripple value. The ripple value is preceded on the display by an indicator of the selected band. For example,
when the ripple value is preceded by “B2”, this indicates that the ripple value shown is for Band 2. The frequency band
indicator and ripple value are displayed in the same color as the pass/fail message for the overall ripple test. When
ABSOLUTE is selected, the display shows the absolute ripple of the data trace within the frequency band. When
MARGIN is selected, the display shows the difference between the maximum allowable ripple and the absolute ripple
value within the frequency band. When the margin value is preceded by a plus sign (+), this indicates that the ripple
within the selected frequency band is passing by the value shown. When the margin value is preceded by a negative
sign (−), this indicates that the ripple within the selected band is failing by the value shown.
RIPL VALUE BAND. selects a frequency band to display the ripple value. When RIPL VALUE [ ] is set to the absolute or
margin choices, this softkey selects the ripple measurement for the selected frequency band.
RIPPLE LIM LINES. selects ripple limit line trace on the display color modification.
RIPPLE LIMIT. selects the ripple limit line choice. This selection leads to menus used to define ripple limits or
specifications with which to compare a test device. Refer to the “Using Ripple Limits to Test a Device” section in the
“Making Measurements” chapter of the user’s guide.
ROUND SECONDS. resets the seconds counter to zero in real-time clock.
S PARAMETERS. presents the S-parameter menu, which is used to define the input ports and test set direction for
S-parameter measurements.
S11 1-PORT. provides a measurement calibration for reflection-only. Measurements of one-port devices or properly
terminated two-port devices, at port 1 of an S-parameter test set.
S11A. is used to enter the standard numbers for the first class required for an S
11
1-port calibration. (For default cal
kits, this is the open.)
S11B. is used to enter the standard numbers for the second class required for an S
11
1-port calibration. (For default cal
kits, this is the short.)
S11C. is used to enter the standard numbers for the third class required for an S
11
1-port calibration. (For default kits,
