Utility Card for In-Circuit Test

The Keysight Medalist i3070 Series 5 In-Circuit Test (ICT) system introduces a new Utility Card that enables: 

1. Flexibility to incorporate external circuits to balance between ICT & Functional testers and reduce investment on functional testers 
2. A wider range of power handling capabilities for today’s high powered products, to reduce investment on power supply hardware  

This data sheet describes the features found on the Keysight Technologies, Inc. utility card. These include: 

• Capability to add external electronics circuit boards by plugging the boards directly onto the utility card.
•  Connection of external signals and instruments through two balanced 1:4 multiplexed signal ports. 
• Control and isolation of external signals through eight general purpose relays. 
• Flexible power supply multiplexing that allows up to six boards on a panel to be powered up using one power supply, or to allow for high current power to be supplied to one board. 

Utility Card Features Balanced 1:4 multiplexed 75 Ω ports and general purpose relays

Two balanced 1:4 multiplexed 75 Ω ports are available on the utility card to allow users to add differential signals to the board under test through the utility card. These ports can be used individually for single sided signals allowing for up to four single ended signals to be channeled through the utility card.  

Flexible 1:6 multiplexed power supply channels

 The utility card allows 50 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. 

 Plug-in electronics 

Plug-in card mechanical speciications The mechanical specifications of the plug-in card are described in Table 2. 

 Utility Card Features Plug-in electronics 

Electrical speciications of the utility card There are three empty slots designed into the utility card to allow users to add three external electronics on the card. The external electronics or plugin card will drive or receive signals from the unit under test through the MINT pins on the utility card that are connected to the slots. Each MINT pin is isolated from the external electronics using relays. Like other pin cards, there are 78 MINT pins on the utility card. Keysight Medalist software or the control card on the testhead will only control the 18 disconnect relays to the 18 signals pin on the 30 pins connector and not the plug-in card circuitry or features. All controls to the plug-in cards will be done by the application software in the form of a .dll that comes from the manufacturer that is installed and run on the PC controller of the test system. The .dll is written by third party vendors who will provide the plug-in card that will be installed on the utility card. The Keysight Medalist software has included APIs that allow the BT-Basic environment to communicate with the .dll in order to control the plug-in card on the utility card. The PC controller communicates with the plug-in cards via USB or Ethernet. The USB would be provided as a main port connected to a hub class device on the utility card. Each plug-in card would then implement its own class of USB device as to be interpreted by the Window XP based PC controller. For more details on the design of the plug-in card or associated .dll, please call your nearest Keysight sales representative who will put you in touch with our in-circuit test experts for further discussions.
