Latest Features on the Series 5 ICT System
Incorporating External Electronics
This capability is enabled through
both hardware and software features
added to the i3070 Series 5 test
system.
Introduction of utility card
The new utility card is an optional pin
card that will fit in a card slot in any
of the modules on the testhead. It
has three cavities in the card to allow
users to plug in their own custom
electronics for added functional test
or functionality during ICT. The user
can now design his own card and
make it part of the tester. One utility
card can be installed on each module.
Each custom electronics unit should
come with the necessary software
drivers that can be installed on the
testhead controller.
Each cavity on the utility card has two
connectors; one is mainly for a signal
bus to the board under test and the
other for power and control to the
external electronics installed in the
cavity.
Please refer to the Agilent data sheet
5990-4411EN (Agilent Utility Card
Specifications) for more details on the
utility card.

functional tests to be added at the in-circuit test process
Connecting external
instruments or equipment
Balanced multiplexed 1:4 75 Ω ports
Two balanced 1:4 multiplexed 75Ω
ports are available on the utility card
to allow users to add differential
signals to the board under test. These
ports can be used individually for
single sided signals.
Parameter Rating
Number of ports 2
Multiplexing 1:4
Bandwidth 3 dB
(at 35 MHz ±3 MHz)
Crosstalk < 1 MHz
(–55 dB ±2 dB)
Maximum current 2 A ±0.5 A
Impedance 75 Ω per pair
General purpose relays
Eight general purpose relays are avail-
able on the utility card. The control of
these relays in software is the same
as for the general purpose relays on
the ASRU.
Flexible 1:6 multiplexed power
supply channels
The Utility Card allows 48 V at
10 A on each of two 1:6 port power
supply channels. Each power supply
channel can be user-configured to be
multiplexed to supply power to up to
six individual boards on a panel or the
individual relays can be configured to
switch together to enable testing of
a single board which requires 10 A
current power supplies.
