Introduction
LXI Class-C Compliant N432A
The N432A is a single- channel, average RF power measurement meter that
supports thermistor sensors. The N432A has the capability to measure and
display average power, RF bridge voltages (V
bridge voltages (V
a set of features such as zeroing and a built- in self- test.
Developed using LXI technology, the N432A is an LXI Class- C compliant
instrument. LXI, an acronym for LAN eXtension for Instrumentation, is an
instrument standard for devices that use the Ethernet (LAN) as their
primary communication interface.
The N432A basic configuration consists of two key sections; bridge and
meter logic. When a compatible thermistor sensor is connected to the
N432A, the RF and compensation bridge circuits are formed in the bridge
section. V
to both input RF power and ambient temperature changes. On the other
hand, V
is responsive only to ambient temperature changes. The V
values are used in calculating the RF power. Meanwhile, the meter logic
section processes V
to RF power.
In general, the N432A is an easy- to- use instrument especially with the
availability of an integrated Web browser that provides a convenient way
to view and modify the instrument network configuration.
Besides the LAN interface, the N432A also supports industry standard
GPIB and USB interfaces for measurement automation.
