Analyzer Functions
(Option 010 only) remembers a specified window pulse
width (or step rise time) different from the standard
window values. A window is activated only for viewing a
time domain response, and does not affect a displayed
frequency domain response.
lets you control the analyzer with the computer over GPIB
as with the talker/listener mode, and also allows the
analyzer to become a controller in order to plot, print, or
directly access an external disk. During this peripheral
operation, the host computer is free to perform other
internal tasks that do not require use of the bus (the bus is
tied up by the network analyzer during this time).
The pass control mode requires that the external
controller is programmed to respond to a request for
control and to issue a take control command. When the
peripheral operation is complete, the analyzer passes
control back to the computer. Refer to the GPIB
programming chapters in the programmer's guide for
more information.
In general, use the talker/listener mode for programming
the analyzer unless direct peripheral access is required.
selects the A or B power sensor calibration factor list for
use in power meter calibration measurements.
is used to select the preset condition defined by the user.
is used to define kits other than those offered by Agilent
Technologies.
selects a menu of user settings, including preset settings
that can be changed by the user.
enters the velocity factor used by the analyzer to calculate
equivalent electrical length in distance-to-fault
measurements using the time domain option. Values
entered should be less than 1.
Velocity factor is the ratio of the velocity of wave
propagation in a coaxial cable to the velocity of wave
propagation in free space. Most cables have a relative
velocity of about 0.66 the speed in free space. This velocity
depends on the relative permittivity of the cable dielectric
