12 Agilent 85309A H20, H21 Operating and Service Manual Modification
Introduction Introduction This operating and service manual modification describes the differences in the Agilent 85309A H20 and H21 options compared to the standard Agilent 85309A LO/IF distribution unit. It also describes the manual changes necessary to document the Agilent 85309A H20 and H21. Description The Agilent 85309A H20 and H21 are broadband, distributed frequency converters that utilize fundamental mixing to provide the performance required for antenna measurement systems.
Introduction • At the recommended +10 dBm setting, spur levels should be no greater than –100 dB. • With a power level of as much as +23 dBm, spurs may be detected as high as –60 dB.
Revised Installation Revised Installation The following modifies the “Installation” section of the Agilent 85309A Operating and Service Manual, pages 2-5 through 2-7. AC Power Connections No line voltage selector setting is required. The ac input power that the option H20 and H21 can accept is 90 to 132 Vac or 198 to 264 Vac at 50-60 Hz.
Revised Operations Revised Operations The following modifies the “Operations” section of the Agilent 85309A Operating and Service Manual, page 3-2 through 3-4. Front and Rear Panel Feature Changes A green LED on the instrument’s front panel (left side) indicates which measurement band has been selected. LED ON indicates HIGH BAND has been selected and LED OFF indicates LOW BAND has been selected. Figures 1 and 2 show typical front and rear panels.
Revised Operations All rear panel functional descriptions are the same for the HIGH or LOW band operations. J15 Rear Panel Port, HIGH/LOW BAND SELECT When the front panel BAND SELECT switch is set to EXT, this port can be used to select the operating band desired by the following TTL levels: HIGH BAND: > + 4 Vdc LOW BAND: < 0.5 Vdc J7 and J8 (using nondiplexed mixers) These two rear panel ports are not available on the Agilent 85309A H20, and H21 options.
