is used to enter the standard numbers for the reverse
transmission (thru) calibration. (For default kits, this is
the thru.)
provides access to the menu for selecting an open
calibration type when the cal kit defines more than one
open standard.
adjusts the source frequency higher than the LO by the
amount of the LO (within the limits of the analyzer).
adjusts the source frequency lower than the LO by the
amount of the LO (within the limits of the analyzer).
draws a quarter-page plot in the lower right quadrant of
the page.
draws a quarter-page plot in the upper right quadrant of
the page.
displays lines that represent the ripple limits when the
ripple test is set to ON.
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.
