The 11970 Series Harmonic Mixers are fully com-
patible with the Agilent E4407B, 8560E/EC Series,
8566B, and 71000 Series Spectrum Analyzers.
Accurate frequency and amplitude measurements
are made directly from the spectrum analyzer’s
display after calibration using the mixer’s calibra-
tion chart. The 11975A Microwatt Power Amplifier
can be used with the 8566B Spectrum Analyzer to
provide the necessary LO power of 14 to 18 dBm to
the mixers. The 11975A has internal power leveling
to achieve maximum measurement accuracy.

1. The Agilent 11975A amplifier (2 to 8 GHz) or a similar amplifier can be used to provide sufficient LO power (14 to 18 dBm) to the mixers.
An LO power of between 14.5 to 16 dBm at the mixer’s LO input is necessary to achieve the given frequency response and spectrum
analyzer amplitude accuracy specifications. When LO power varies between 14 to 18 dBm at the mixer’s LO input, add ±1 dB to the
frequency response and spectrum analyzer amplitude accuracy specification. 3
