HP 3048A Description
What is the HP 3048A?
The HP 3048A provides you a standard process for measuring phase noise.
It allows you to measure sources of many types with a flexible system
configuration.
The HP 3048A Phase Noise Measurement System includes:
• The HP 11848A Phase Noise Interface, an interface box specifi-
cally designed for high performance phase noise measurements. The
HP 11848A supports several measurement techniques for phase noise
and AM noise measurement. Built in to the interface are phase de-
tectors, amplifiers, filters, and switches necessary to measure phase
noise over a frequency range of 5 MHz to 18 GHz. An input for an
external phase detector outside the above mentioned frequency range
is also provided. Internal sources are provided to allow the system to
functionally check all of its signal handling circuits insuring proper
operation prior to making a measurement.
• The HP 3561A Dynamic Signal Analyzer, a Fast Fourier Transform
analyzer of a wide frequency range (125 fiHz to 100 kHz). The
HP 3561A has built-in data averaging capabilities, large dynamic
range, and fast measurement speed which make it ideal for quantifying
demodulated phase noise (noise voltages).
• Measurement software, a program that includes all drivers necessary
to run both standard and optional instruments of the HP 3048A
system.
• Operator's Training, an operator's training course that explains all of
the operating modes and measurement techniques of the HP 3048A,
when each technique is appropriate, and how to analyze the measured
data.
