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.

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.

General Information
Electrostatic Discharge
Electrostatic Discharge
Protection against ESD (electrostatic discharge) is essential while connecting, inspecting,
or cleaning connectors attached to a static-sensitive circuit (such as those found in test
sets).
Static electricity can build up on your body and can easily damage sensitive internal
circuit elements when discharged. Static discharges too small to be felt can cause
permanent damage. Devices such as calibration components and devices under test
(DUTs), can also carry an electrostatic charge. To prevent damage to the test set,
components, and devices:
•always wear a grounded wrist strap having a 1 MΩresistor in series with it when
handling components and devices or when making connections to the test set.
•always use a grounded, conductive table mat while making connections.
•always wear a heel strap when working in an area with a conductive floor. If you are
uncertain about the conductivity of your floor, wear a heel strap.
•always ground yourself before you clean, inspect, or make a connection to a
static-sensitive device or test port. You can, for example, grasp the grounded outer shell
of the test port or cable connector briefly.
•always ground the center conductor of a test cable before making a connection to the
analyzer test port or other static-sensitive device. This can be done as follows:
1. Connect a short (from your calibration kit) to one end of the cable to short the center
conductor to the outer conductor.
2. While wearing a grounded wrist strap, grasp the outer shell of the cable connector.
3. Connect the other end of the cable to the test port.
4. Remove the short from the cable.
Figure 1-4 shows a typical ESD protection setup using a grounded mat and wrist strap. For
parts numbers of ESD protection supplies, refer to “Replaceable Parts” in chapter 6 of the
Electronic Calibration Module Reference Guide.
