Agilent 85309A H40, H41, H42 Operating and Service Manual Modification 1
Introduction
Introduction
This operating and service manual modification describes the differences in
the Agilent Technologies 85309A H40, H41 and H42 options compared to
the standard Agilent Technologies 85309A option 001 LO/IF distribution
unit. It also describes the manual changes necessary to document the Agilent
Technologies 85309A H40, H41 and H42.
Description The Agilent Technologies 85309A H40, H41 and H42 are broadband,
distributed frequency converters that utilize fundamental mixing to provide
the performance required for antenna measurement systems. The
Agilent Technologies 85309A H40, H41 and H42 have one reference
channel, up to three test channels, and operate from 100 MHz to 18 GHz in
two overlapping bands, as follows:
The measurement bands can be selected manually from the instrument’s
front panel BAND SELECT switch or the TTL interface provided at the rear
panel SELECT port for automated control.
Option Definition The Agilent Technologies 85309A H40, H41 and H42 are distinguished by
the number of test channels available, as follows:
NOTE Use Agilent Technologies 85320A/B option H20 external mixer modules to
utilize the 0.1 to 3 GHz frequency range of operation.
Agilent Technologies
8836xx Series LO
Source Operation Note
When using an Agilent Technologies 8360 series synthesized sweeper as the
LO source, set the output power level to approximately +10 dBm in order to
minimize potential Agilent Technologies 85310A system-generated spurious
signals in the 0.1 to 3 GHz range.
Band Operating Frequency
Low band 0.1 to 1 GHz
High band 0.3 to 18 GHz
