VNA Interface Kit Setup and Operation
VNA Interface Kit Setup and Operation
The VNA-based ECal system requires the following components:
• VNA (with appropriate firmware revision) — functions as the ECal system controller
• ECal module — acts as the calibration device for the ECal system
• VNA Interface kit — provides an interface between the ECal module and the VNA
Setup Procedure
Refer to the graphics on the following page for all connections.
Exercise the necessary ESD precautions before connecting the devices. Refer
CAUTION
to
"Electrostatic Discharge" on page
Connect Interface Unit to VNA (DB25 to DB25 Cable)
1. Connect one end of the DB25 to DB25 cable to the connector on the interface unit
lableled "DB25 Interface to Parallel Interface on Network Analyzer."
2. Connect the other end of the DB25 to DB25 cable to the connector on the rear panel of
the VNA lableled "Parallel Port".
Connecting the interface cable to an unspecified connector on the VNA will
CAUTION
cause damage.
Connect RF Module to Interface Unit (DB25 to DB25 Cable)
1. Connect one end of the DB25 to DB25 cable to the parallel port on the ECal module.
2. Connect the other end of the DB25 to DB25 cable to the connector on the interface unit
labeled "DB25 Interface to ECal Module A" or "DB25 Interface to ECal Module B".
Connect Microwave Module to Interface Unit (DB25 to AMP Champ Cable)
1. Connect the AMP Champ end of the adapter cable to the parallel port on the ECal
module. Press the tabs on the connector housing to engage the connector.
2. Connect the DB25 end of the adapter cable to the connector on the interface unit labeled
"DB25 Interface to ECal Module A" or "DB25 Interface to ECal Module B".
Connect Interface Unit to Power Supply
1. Connect the interface power supply to the interface unit and then connect to AC power.
2. Allow the ECal module to warm up for 15 minutes (20 minutes for a four-port module)
or until the module indicates READY.
3. ECal module is ready to perform a calibration. Press the
access the calibration types available with ECal.
