reformats a reflection measurement into its equivalent
SWR (standing wave ratio) value. SWR is equivalent to
(1+ρ)/(1−ρ), where ρ is the magnitude of the reflection
coefficient. Note that the results are valid only for
reflection measurements. If the SWR format is used for

is the mode used when peripheral devices are to be used
and there is no external controller. In this mode, the
analyzer can directly control peripherals (plotter, printer,
disk drive, or power meter). System controller mode must
be set in order for the analyzer to access peripherals from
the front panel to plot, print, store on disk, or perform
power meter functions, if there is no other controller on
the bus.
The system controller mode can be used without
knowledge of HP-IB programming. However, the HP-IB
address must be entered for each peripheral device.
This mode can only be selected manually from the
analyzer's front panel, and can be used only if no active
computer controller is connected to the system through
HP-IB. If you try to set system controller mode when
another controller is present, the message ANOTHER
SYSTEM CONTROLLER ON HP-IB BUS is displayed. Do not
attempt to use this mode for programming.
Each data point is measured during the initial sweep and
the correction data is placed in the power meter correction
table. This provides data usable in the
mode.

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.
