HP 85105A mm-Wave Controller
Rear Panel Features
5. RF Input
This input comes from the RF source via the RF switch. When the test set
module is selected by the HP 8510 the RF is amplified and then input to a
switch that directs the RF to either port 1 or 2. When the coaxial test set is
selected by the HP 8510 the RF is switched to the connector labeled
"RF OUTPUT" located on the rear panel of the HP 85105A.
NOTE The HP 85105A standard and Option 004 connectors, number 5 and 6, are
3.5 mm female.
The HP 85105A Option 050 connectors, number 5 and 6, are 2.4 mm female
adapters to accommodate 50 GHz operation.
6. RF Output
When the port is selected by the analyzer, an amplified RF source signal is
available to an HP 85104A test set module, or to a multiplier for customer
configured systems.
7. J10 Test Set Interconnect
Should be connected to J11 of the coaxial test set. This connector transmits
the IF signals from the test set to the HP 85105A.
8. J11 Test Set Interconnect
Should be connected to the J1 Test Set Interconnect on the HP 85102
IF/Detector. This connector transmits the IF signals from the HP 85105A to
the HP 85102 IF/Detector. It also transmits control signals.
9. HP 8510 System Bus Address Switch
This five-pole binary-weighted switch sets the system bus address of the
instrument. The binary weight of each pole is indicated on the rear panel as
are the on and off positions. Decimal twenty one, binary 10101 (on, off, on,
off, on) is the default setting.
10. J12 EP 8510 System Bus Connector
This connector is used for system HP-IB communications with the
HP 85101 display/processor.
