Overview
This procedure describes how to use the HP 70427A Downconverter
Module and the HP 11970 series harmonic mixer with the HP 3048A or
HP 3047A Phase Noise Measurement Systems. The external harmonic
mixer accepts a signal from 18 GHz to 110 GHz, depending on the mixer’s
frequency band, and applies a signal to the downconverter’s
SIGNAL
input
between 5 MHz and 1200 MHz. The downconverter supplies the external
harmonic mixer with mixer bias current and a 2.4 GHz to 6 GHz signal
which the harmonic mixer multiplies internally to produce the mm LO.

Millimeter Phase Noise Measurement - User Control Connection
Refer to Hewlett-Packard Application Note 385 for information on making
millimeter phase noise measurements and to the harmonic mixer manual for
information on the harmonic mixer.
This procedure can be used for all HP 3048A and HP 3047A software
versions. The HP 70427A is controlled manually.
The HP 8662A and HP 8663A can be used under system control with the
any HP 3048A software version. See the HP 3048A manual for details.
