Introduction
Introduction
This manual supplement describes the differences in the 85320A H50 and
the 85320B H50 as compared to the standard 85320A/B. It also describes the
manual changes necessary to document the Agilent 85320A/B option H50
Description
The 85320A H50 and the 85320B H50 are identical in function to the
standard 85320A and 85320B except that the frequency range of operation is
2 to 50 GHz instead of 2 to 26.5 GHz.
The 85320A H50 test mixer and the 85320B H50 reference mixer are
designed for use with the 85309A distributed frequency converter as
described in the 85320A/B Mixer Module User’s Guide. These mixers allow
operation over the full 2 to 50 GHz frequency range. See the System
Performance Notes section for more details.
Agilent 85320A/B H50 Operating and Service Manual Supplement 1
Operating Note
Operating Note
Internal Crystal
Detector Output
Voltage Label
The 85320B H50 reference mixer module has a label attached to it; the
bottom half of the label has a millivolt value scale marking. The marking
indicates what the internal crystal detector output voltage is when
approximately +16 dBm, at 6 GHz, is being applied to the 85320B LO Input
port.
The marked reading value can be used to set the 85309A front panel display
reading. This value should provide the required LO drive level to the
85320 mixers when used in an 85310 system configuration.
If the LO drive coax cables used to conduct this 2-18 GHz drive signal from
the 85309A to 85320 mixers has an excessive amount of loss, either by
being extremely long or lossy, the label reading will not be achievable over
the full 2 to 18 GHz range.
A failure to achieve this setting on the 85309A is indicated by the “Red”
front panel indicator coming on during some portion of the 2-18 GHz LO
frequency band. If the “Red” indicator flashes ON, refer to Appendix A for
an alternate L.O. drive power setting.
NOTE
The new drive power setting will require that you lower the drive power to
as low as the minimum +12 dBm level.

Optimizing LO Drive Power
There are special system configurations in which the recommended
“detector voltage” reading on the Agilent 85320B mixer module is not
compatible. The “detector voltage” value that is on the mixer module
assumes that the LO coax cables (B2, B3) used to interface the Agilent
85309A to the Agilent 85320 mixers are similar to the Agilent 85381A cable
assembly that is not greater than 5 meters in length or a cable loss of less
than 5 dB at 18 GHz.
Determining Detector
Voltage
Procedure
Figure A-1
To determine the correct “detector voltage” for your special application,
follow this procedure.
1. Configure your equipment as shown in Figure A-1 below.
Equipment Configuration
2. Calibrate and Zero the power meter and sensor
3. Connect the power sensor to the end of the “B3” cable.

4. Set the Agilent 85309A front panel display reading to the value
indicated on the Agilent 85320B mixer.
5. Manually set the RF source so that it will slowly sweep across the LO
frequency range that you wish to operate in. Note power meter settling
time requirement.
6. If the Red front panel indicator light on the Agilent 85309A does not
flash ON and the minimum power measured by the power sensor (minus
the 10 dB attenuator loss) is > +12 dBm, then use this detector voltage
setting.
7. If the Red indicator light flashes, readjust the Agilent 85309A front
panel adjustment to a lower value until the Red indicator light no longer
flashes. Now insure that the minimum measured power is > +12 dBm.
If you are not able to achieve a > +12 dBm power reading with no Red
indicator, you have one of these possible problems:
a. B2 and B3 cable length are too lossy, find alternative.
b. Cable B3 or B2 are not equal or one is defective.
c. The Agilent 85309A is defective. Insure that the power levels at
ports J2 and J3 (without the Agilent 85320B connected) exceed their
specified levels.
New Voltage Marking
ADD New Voltage Marking to Agilent 85320B Label
For future reference in this special system configuration, it is recommended
that you re-mark the Agilent 85320B millivolt scale to indicate the new
system detector voltage value.
Next to the new marked value, note the minimum LO power level measured
during the measurement portion of this procedure.
