Analyzer Functions
is the mode normally used for remote programming of the
analyzer. In this mode, the analyzer and all peripheral
devices are controlled from the external controller. The
controller can command the analyzer to talk, and the
plotter or other device to listen. The analyzer and
peripheral devices cannot talk directly to each other
unless the computer sets up a data path between them.
This mode allows the analyzer to be either a talker or a
listener, as required by the controlling computer for the
particular operation in progress.
A talker is a device capable of sending out data when it is
addressed to talk. There can be only one talker at any
given time. The analyzer is a talker when it sends
information over the bus.
A listener is a device capable of receiving data when it is
addressed to listen. There can be any number of listeners
at any given time. The analyzer is a listener when it is
controlled over the bus by a computer.
makes target value the active function, and places the
active marker at a specified target point on the trace. The
default target value is −3 dB. The target menu is
presented, providing search right and search left options
to resolve multiple solutions.
For relative measurements, a search reference must be
defined with a delta marker or a fixed marker before the
search is activated.
sets the value for target searches, without activating a
search.
is used to specify the (arbitrary) impedance of the
standard, in Ωs.
is used to set configurations before running the service
tests.
is used to direct the RF power to port 1 or port 2. (For
non-S parameter inputs only.)
is used to support specialized test sets, such as a test set
that measures duplexers. It allows you to set three bits
(D1, D2, and D3) to a value of 0 to 7, and outputs it as
binary from the rear panel test set connector. It tracks the
coupling flag, so if coupling is on, and FWD channel 1 is
the active channel, FWD channel 2 will be set to the same
value.
