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
reversed between sweeps to accomplish measurement
of both input and output responses.) The required standards are
a short, an open, a 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 ohms, but delay and loss offsets may still
be added. Pressing this key also brings up a menu for defining
the open, including its capacitance.
gets data from an HP-IB device set to the address at which the
analyzer expects to a power meter. The data is stored in a
title string. The analyzer must be in system controller or pass
control mode.
while creating a sequence, this will insert a command
that selects the single bit (0 to 4) that a sequence will be
looking for from the GPIO bus.
while creating a sequence, this
inserts a command to
jump to another sequence if the single input selected is in a
high state.
while creating a sequence, this
inserts a command to
jump to another sequence if the single input selected is in a low
state.
sets the printer or plotter port to
toggles the parallel output port between the copy and GPIO
output modes.
allows you to input a number (0 to 255) in base 10, and outputs
it to the bus as binary, when the parallel port is in GPIO mode.
pauses the sequence so the operator can perform a needed task,
such as changing the DUT, changing the calibration standard, or
other similar task. Press when ready.
