1-28 N67xx DUT Power Supply Installation

Updating the Configuration Files

The power supply connections must be defined in the system and standard config

files:

\I3070_ICT_ROOT\diagnostics\th1\config

\I3070_ICT_ROOT\standard\config

Use the supplies statement.

supplies <type> <#> asru channel <#>

• The supplies type can be ps6751, ps6752, ps6746, or ps6773 depending on

which power supply was installed.

• The first number or range of numbers gives the testhead supply number

(

1 through 24). The numbering of the supplies in the supplies statement is

arbitrary. The software will accept any mapping of supply numbers to modules.

However, you cannot assign a power supply number more than once in a

testhead. If the customer has more than one system, make the new

supplies

statement compatible with the other system.

• The second number or range of numbers gives the ASRU Card DUT channel.

This must match the physical connection of the supply to the ASRU card. You

cannot assign a channel number (1 through 6) more than once in a module.

The following table shows the default and alternate power supply mapping for each

module and the proper syntax for each type of power supply.

After the

config files have been updated, compile both files.

If the new power supply has been placed on a wrong channel,

you will get a compiler error.

Verifying Operation

1 Look at the Testhead Config screen and verify that the official configuration

agrees with the actual configuration.

2 Run Diagnostics, especially the DUT power supply tests, with a pin verification

fixture.

In Case of Difficulty

If you need phone support, go to www.keysight.com/find/contactus for contact

information.

If Diagnostics fails, verify that there are no shorting straps on

the terminals. Some supplies come from the factory with

shorting straps. They must be removed to do remote sensing.
