Model: 8970A
Date: 1985
Category: Measurement instruments
Group: Level Meter
Description: Noise Figure Meter
Information:
                                    The 8970A Noise Figure Meter is a very sensitive, tunable,
automatic receiver. Its capability is greatly enhanced by a
microprocessor used for many control, timing, and
calculation purposes. With an appropriate solid state noise
source, such as the 346B Noise Source, it automatically
measures the noise figure of the device under test (DUT)
inserted between the output of the noise source and the
input of the 8970A. The 8970A may be tuned to any frequency
between 10 and 1500 MHz and digitally swept over all or part
of this range. To measure DUT’s with output frequencies
greater than 1500 M Hz, an external mixer and local
oscillator (LO) are required to down convert the frequency
into the 10 to 1500 M Hz range. The 8970A can also
automatically remove the noise contribution of the second
stage (the measurement system) from the measurement. It can
measure and display both gain and noise figure of the DUT.
