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. 2 Agilent 85320A/B H50 Operating and Service Manual Supplement Specification Specification Operating Frequency Range 2 to 18 GHz (fundamental mixing mode) Maximum Input Levels Maximum RF level at RF and LO inputs (damage level): +20 dBm 18 to 50 GHz (3rd harmonic mode) Table 1 LO Frequency Minimum Power Typical Power Maximum Power 2 - 18 GHz +12 dBm +14 dBm +17 dBm Table 2 General Specifications LO Input Levels Conversion Loss (LO at +12 dBm) RF Frequency LO Harmonic LO Frequency Typical Loss Maximum Loss 2 - 18 GHz fundamental 2 - 18 GHz -6 dB 15 dB 18 - 50 GHz 3 rd. 6 - 16.7 GHz -24 dB 30 dB Connector Types Type-N female except for R.F.

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. Agilent 85320A/B H50 Operating and Service Manual Supplement A-1 Appendix A 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.
