constant of the medium, and the speed of light.
completes the selection in the Offset Load Menu.
is used to specify energy loss, due to skin effect, along a
one-way length of coax offset. The value of loss is entered
as Ωs/nanosecond (or Giga Ωs/second) at 1 GHz. (Such
losses are negligible in waveguide, so enter 0 as the loss
offset.)
is used to specify the characteristic impedance of the coax
offset. (Note: This is not the impedance of the standard
itself.) (For waveguide, the offset impedance should always
be assigned a value equal to the system Z0.)
is used to omit the isolation portion of the calibration.
leads to the series of menus used to perform a
high-accuracy two-port calibration without an
S-parameter test set. This calibration procedure
effectively removes directivity, source match, load match,
isolation, reflection tracking, and transmission tracking
errors in one direction only. Isolation correction can be
omitted for measurements of devices with limited dynamic
range. (The device under test must be manually reversed
between sweeps to accomplish measurement of both input
and output responses.) The required standards are a
short, an open, a thru, and an impedance-matched load.
This mode does not measure each sweep, but corrects each
point with the data currently in the power meter
correction table.
provides a tabular listing on the analyzer display of the
key parameters for both channels. The screen menu is
presented to allow hard copy listings and access new pages
of the table. Four pages of information are supplied. These
pages list operating parameters, marker parameters, and
system parameters that relate to control of peripheral
devices rather than selection of measurement parameters.
defines the standard type as an open, used for calibrating
reflection measurements. Opens are assigned a terminal
impedance of infinite Ωs, but delay and loss offsets may
still be added.
for cal kits with different models for male and female test
port standards, this selects the open model for a female
test port. Note that the sex of a calibration standard
always refers to the test port.
