What can you expect from a high-speed and
high-density switching system that’s this affordable ?

Performance you can trust

While traditional switching mainframes open/close
relays in sequence, the HP 3499A/B use innovative
parallel driving circuits to open/close switches
simultaneously. The HP 3499A can drive up to 50
channels in 25 ms. The parallel operation of the HP
3499A/B significantly increases the test throughput of
an automated test system.

HP 3499 family also provides high-density modules with
up to 40 channels per module. Two multi-function
modules integrate switching and digital I/O in one
module and enhance system performance.

Powerful flexibility to get your job done

We put in a lot of effort to make the HP 3499 switching
family products as flexible as possible, so that it can be
tailored to meet your needs.

HP 3499 family includes two mainframes. HP 3499A is a
5-slot mainframe and HP 3499B, a 2-slot mainframe.
These two mainframes will accommodate a full range
of 19 different modules, including multiplexer, general
purpose relay, matrix, digital I/O, VHF module, RF
module, microwave module, Form-C relay, and two
special multifunction modules. By combining these
mainframes and modules, test engineers can set up
their test system with fewer modules in less space and
also reduce the cost and complexity of the test system.

High-speed and high-density switching solution ideal for automatic test

Customize your test system
with 2 mainframes and 19 modules

Test engineers want "just enough" testing and do not
want to pay extra for something they do not plan to use
immediately. The 2 mainframes and 19 modules allow
you to customize the HP 3499 switch and control
system to meet your unique requirements. Buy only
what you need - and add more modules later as your
application grows.

The HP 3499 family allows the user to select a cost­effective configuration for specific applications. Newly
designed high density switch modules reduce cost by
compacting a large number of channels on a single
module. The HP 3499A contains 5 slots that can
accommodate up to 200 channels switching for those
large switching applications on the manufacturing floor.
The HP 3499B contains 2 slots for switching up to 80
channels, a cost-effective solution for small
manufacturing or desktop applications. Both units are
designed for easy installation in a standard rack.

Use high-density modules or multifunction modules to
save money and space

HP 3499 family provides modules that contain up to 40
switching channels per module. This will greatly reduce
the per channel cost and save rack and floor space. T est
engineers can set up the test system with fewer
modules using less space and also reduce the cost and
complexity of the test system. The result is that users
spend less money without sacrificing performance and
quality.

Two multifunction modules are also introduced along
with the HP 3499 family. The N2264A includes 12
general purpose relay channels, 3 high current general
purpose relay channels, and 16 bits of digital I/O. The
N2265A combines a 4x4 matrix switch with 16 bits of
digital I/O on one module. With HP 3499B, users can
configure a small but versatile switching/control test
system. The 3 power relay channels in N2264A can
switch signals up to 5 A. These power relays are very
useful in test systems such as cellular phone test,
battery test and UPS test where only two or three high
current channels are required.

Easy wiring with versatile module connection
accessories

We understand that wiring requires a lot of your time
and energy, and the HP 3499 switching products have
been designed to make it easier for you. The HP 3499
family provides two connection accessories to minimize
your wiring time and effort. Both the removable screw
terminal blocks and crimp & insert terminal blocks are
detachable from the switching modules, eliminating the
need for rewiring the connector if a switching module
is replaced.

The six high-density modules use industry standard
DIN96 connectors for better flexibility. The modules
are equipped with DIN96-to-D50(25) cables for easy
connection to the DUT and test instruments. Using
these cables, you have completely eliminated all wiring.

Built-in relay cycle counter
to facilitate test system maintenance

In a high-speed automatic test equipment (ATE)
system, unplanned downtime can be fatal to a high­yield production line. To help test engineers perform
preventative maintenance by predicting relay end-of­life, there are built-in relay cycle counters on the 5
high-density switching modules, thereby avoiding
costly production line downtime. The relay cycle
counter automatically counts every individual relay
closure and stores the number in the on-board non­volatile memory. A simple "DIAG: CYC? Chan. xx "
command recalls the total number of cycles for
individual relays, making scheduled preventative
maintenance possible.

Compatibility with HP 3488A

The HP 3499 family is both hardware and software
compatible to the world's most popular switch/control
unit -the HP 3488A. All 13 of the HP 3488A modules
will work in the HP 3499A/B mainframes. The HP
3499A/B can be operated with SCPI (Standard
Commands for Programmable Instruments) or the HP
3488A command sets. Upgrading from an HP 3488A to
an HP 3499A doubles your channel capacity and lowers
your cost per channel with no additional cost in
modules.

Application examples

Cellular phone test

In a typical cellular phone final test system there is a
switch system, a GSM/CDMA test set, a DMM (digital
multimeter), a power supply, and a spectrum analyzer.
An HP 3499A with a multifunction module (N2264A), a
digital I/O module (N2263A), and a matrix module
(N2262A) provides the switching solution needed in
this test system. The 3 general purpose high current
relays in the N2264A switch the cellular phone power
supplies --- main battery, backup battery, or charger.
With the 3 relays on N2264A, the DMM tests the
sleeping, standby, and working current - between 0.1
mA and about 4 A. Eight bits of digital I/O drives the
external solenoid coils to simulate key pressing. Eight
additional bits of digital I/O are used to drive a coaxial
relay to route the RF signal coming from the phone
antenna to GSM/CDMA test set for camping, call setup,
power level, BER test, or to spectrum analyzer for
spectrum leakage tests. Three more bits of digital I/O
are used to communicate with the cellular phone under
test. Working with the DMM, the matrix module
switches the voice signals to/from the cellular phone for
audio testing.

Pager Test

A typical test system that tests the pager PC board
consists of an HP 3499B equipped with one multiplexer
module (N2260A), one matrix module (N2262A), one
DMM, and one power supply. This compact test system
can test one pager. In this configuration, one 2-meter
rack is capable of holding 6-8 test systems. One matrix
channel switches the DUT (pager) on/off. Using a
multiplexer channel, the DMM tests the bias voltage of
the mixer, front-end amplifier, and filters to ensure that
the different circuits of the pager are working properly.
Using a multiplexer channel, the DMM also tests the
working/standby current to ensure the battery
operating time specification is met.

Customize your HP 3499A/B with plug-in modules

We invested a lot of time and energy in studying actual switching applications and tailoring the switching
modules for different applications. Six high density modules (HP N2260A, N2261A, N2262A, N2263A,
N2264A and N2265A) plus the 13 existing modules (HP 44470A/D, 44471A/D, 44472A, 44473A, 44474A,
44475A, 44476A/B, 44477A, and 44478A/B) for the HP 3488A can cover a wide variety of signals with
superior flexibility.

Different switching for applications

A general purpose relay is used to turn on/off the DUT
(device under test), instruments, motors, pumps and
LEDs, or to form an attenuation network with L, C, R
components.

A multiplexer is used for switching signal to
instrumentation by connecting many test points to an
instrument, or a DUT to many instruments. The
instruments can include multimeters, oscilloscopes,
spectrum analyzers, and counters, etc. There are one­wire, two-wire, three-wire or four-wire multiplexers. A
one-wire multiplexer is very useful in high frequency
(30 MHz - 26 GHz) applications and common ended
signal switching. The two-wire multiplexer is very
useful for floating measurements where you need to
switch both the "high" and "low" paths. The three-wire
multiplexer is mostly used for the guarded
measurements that have very high CMRR (Common
Mode Rejection Ratio). The four-wire multiplexer is
mainly used for 4-wire precision ohm measurements.

A matrix switch is used when one or more instruments
are connected to one or more test points at the same
time. By using a matrix switch, you can connect any
point on a column to any point on a row. A matrix
switch offers maximum flexibility, but you need to use
more relays and be careful to avoid crosstalk between
channels.

A digital I/O module has both input & output bits for
digital sensing and is mainly used to control external
devices, such as motors, LEDs, and microwave relays.
The digital I/O can also be used to send and receive
digital patterns to/from the DUT, and to communicate
with other devices.

Six high density modules

Now test engineers have a 40-channel 2-wire
multiplexer in roughly the same space as only one of
the HP 3488A's 10-channel switching modules. The six
high density modules reduce cost by compacting a large
number of channels on a single module. There are also
two multifunction modules for applications a that
require variety of functions in limited space. The
N2264A includes 12 general purpose relay channels, 3
high current channels and 16-bit digital I/O. The
N2265A includes a 4 x 4 matrix switch and 16-bit of
digital I/O. With these two modules and HP 3499B, the
half-rack-width mainframe, you will have a compact
switching unit in a small space and at a low cost!

Flexible channel capacity

The 19 modules in HP 3499 family provide a large
variety of channel selections to match your test system
application (10-200 channels in one mainframe). The
total channel count ranges from 10, 20, to 40 channels
per module. You can customize your HP 3499A/B with
these modules to match the channel count and
switching topologies to meet your individual needs.

4 x 8 Matrix Switch Module

HP N2262A

Description

The HP N2262A is a 4 x 8 matrix module, containing 32 cross
points organized in a 4-row by 8-column configuration. It
provides the most convenient way to connect a group of test

Dual 1 x 4 RF Multiplexer (1.3 GHz, 50/75Ω)

HP 44478A/B

Description

The HP 44478A/B multiplexer module is an ideal choice
for broadband switching of high frequency or fast pulse
signals. Dual 1-to-4 mulitplexers provide bi-directional
switching of signals from DC to 1.3 GHz. High channel
isolation (>55 dB @ 1 GHz) assures quality dynamic­range measurements using spectrum, network, or
distortion analyzers. Each 1-to-4 multiplexer consists of
7 relays in a "tree" structure, which provides high
isolation and low VSWR (voltage standing wave ratio).
All the connectors on the module's edge are female
BNC for ease of wiring. Off-channels can be terminated
in resistors to maintain proper operation of DUT
circuitry. Simply plug a 50/75 Ω SMB type resistive
termination onto the on-board male SMB connector
provided for each channel.

HP 3499A Rack Mount Kit with Handles (Opt. 1CP)

Description

The HP 44477A is a Form-C relay module providing
seven independent Single-Pole-Double-Throw relays
for general purpose switching and control of external
devices. Using an external power supply, you can use
the module to drive remote RF, coaxial, and microwave
devices such as the HP 876xx, HP 8710xx series, and
mercury relays. This module is normally set up to use
an external power supply for voltages up to 250 V DC,
and can be easily configured to use the internal 5 V DC
power supply. In applications where the module's
voltage or current specifications are going to be
exceeded, use the module to drive a properly rated
external relay to switch those signals.
