General Information
VNA Interface Kit Overview
VNA Interface Kit Overview
This manual provides reference information for the Agilent 85097B vector network
analyzer (VNA) interface kit for electronic calibration (ECal).
The VNA interface kit is part of the VNA-based ECal system. The interface kit provides
the hardware to connect and allow data transfer between ECal modules and compatible
network analyzers. See Table 1-1 below.
ECal modules are precision, single-connection devices that provide consistent calibrations
for your network analyzer. ECal uses fully traceable and verifiable electronic standards.
The interface kit does not include the ECal modules, but they can be ordered separately.
For ordering information, see “Contacting Agilent” on page 2-4.
NOTE For more information about ECal modules, refer to the Electronic Calibration
Module Reference Guide (included with the VNA interface kit).
Option 100
Adds an adapter cable that allows the interface kit to connect to N469x (microwave) ECal
modules. The Option 100 adapter cable can also be ordered separately.
Compatible Network Analyzers
Refer to Table 1-1 for network analyzers and ECal modules compatible with the 85097B
VNA interface kit. The network analyzer must have the appropriate firmware revision
installed to operate with the ECal models shown.
NOTE PNA network analyzers are not compatible with the 85097B VNA interface
kit. PNA analyzers allow direct connection of the ECal modules through a
USB connector interface. Refer to the PNA analyzer on-line help system for
more details.

VNA Interface Kit Contents
Description of the VNA Interface Kit Contents
This section describes the contents of the 85097B VNA interface kit. Refer to Figure 1-3 on
page 1-7 for a system setup diagram using the kit contents.
NOTE ECal modules are not included in the 85097B VNA interface kit, but are
ordered separately. Refer to the Electronic Calibration Module Reference
Guide (part number N4693-90001) for information on the types and
specifications of ECal modules.
Interface Unit
The interface unit (shown in Figure 1-1) functions as the digital interface and power source
for ECal modules. The interface can connect to one or two ECal modules. Power is
automatically turned off when an ECal module is disconnected.
NOTE If you are using an 8506xA microwave module with a serial number below
800, a jumper must be installed in the module to make it compatible with the
interface unit. Contact Agilent for information about returning your module
for this modification. Contact information can be found in Table 2-1 on
page 2-4.
Shielded Cables, DB25 to DB25
The shielded cables (shown in Figure 1-1) are male to male RS-232 cables. Three shielded
cables are included in the kit. The cables connect between the VNA and the interface unit
and between the interface unit and one or two ECal modules (except N469x series). The
length of each shielded cable is 1.8 m.
Adapter Cable, DB25 to AMP Champ (Option 100)
The adapter cable (shown in Figure 1-1) is configured with a DB25 to AMP Champ (36-pin)
connector. The adapter cable connects N469x (microwave) ECal modules to the interface
unit. The adapter cable (part no. 8121-1047) can be ordered separately or by adding
Option 100 to the interface kit. The length of the adapter cable is 1.0 m.
CAUTION Use only the interface cables supplied with this kit. Other cables may cause
the system to fail EMC specifications.

ECal Power Supply Unit
The ECal power supply unit (shown in Figure 1-1) provides 24 Vdc to the interface unit
and power to the ECal modules through the interface unit.
WARNING To prevent electrical shock, disconnect from mains before cleaning.
Use a dry cloth or one slightly dampened with water to clean the
external case parts. Do not attempt to clean internally.
CAUTION Always use the three-prong ac power cord supplied with this product. Failure
to insure adequate earth grounding by not using this cord may cause product
damage.
WARNING The detachable power cord is the instrument disconnecting device.
It disconnects the mains circuits from the mains supply before other
parts of the instrument.

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.
CAUTION Exercise the necessary ESD precautions before connecting the devices. Refer
to “Electrostatic Discharge” on page 1-10.
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”.
CAUTION Connecting the interface cable to an unspecified connector on the VNA will
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 Cal button on the VNA to
access the calibration types available with ECal.
