The CB8H looks similar to the CB8, but is designed to operate at higher voltage.

As long as the connectors under test are suitably voltage-rated, the board configurations you see below may be realized with either the CB8 or CB8H.

Clearly, high voltage testing requires an HVX-series tester.

See how these boards are customized for diverse test applications — examples and photos below.

1 - In the photo you see at the right, two pigtail cables provide an interface for circular connectors. Separate circular and DB9 male connectors are mounted on standoffs. The pigtails flow under the board and connect to the test point pads underneath. The flexibility of pigtails make them a good choice when the cable under test is large, heavy, or unwieldy.

You may purchase the CB8 board and ask an in-house technician to mount your custom connectors, or ask us for a quotation to configure and test a CB8 for you.

2 - Here, you see how a circular connector is supported by standoffs and wired to the underside of the board.

3 - Mounted directly to a CB8 board, this LIF block provides quick connection and disconnection while accomodating both an awkwardly shaped connector shell, and the need to test the shield.

The single pogo pin assigned to test the shield is clearly visible in the upper image. The lower image shows a connected sample connector.

Application: Portable Radios

4 - Four different Amphenol/Cannon MIL-Spec circular connectors are mounted with standoffs to this CB8H.

Application: Electric Power Distribution

5 - A large, 19-pin, Amphenol MIL-Spec circular connector is mounted with standoffs to this CB8.

Application: Electric Power Distribution

6 - The DB15 connector mounted to this CB8 has a connector protection device attached (the device with the blue plastic insulator) which looks like a mini gender changer but does not change the gender. It absorbs the wear of repeated cable insertion and can be replaced in seconds when the pins become intermittent or break.

7 - In this photo, you see two DIN8 connectors are mounted to the surface and a miniDIN9 connector recessed into the board and wired from below.

8 - The blue-green wires you see here are actually miniature coaxial cables that mount to a mixed pin Dshell connector at the end of the pigtail. Note the individual flying leads available for power and ground connections.

9 - These large, 56-pin Elco connectors easily mount to our CB8 board, which can support connectors with up to 64 pins. 24-gauge red wire link each pin to one of the terminal pads on the board. For larger pin counts, our CB30 board (Item 760, similar in design to the CB8) can support up to 128 pins.

Note: Each stock CB11 board (Item 741) supports a single 90- or 120-pin Elco/Edac Rack and Panel connector.

10 - We designed this special arrangement to handle a wiring harness that included weatherproof connectors, battery terminals, and single-conductor rubber-insulated high voltage leads.

11 - The black connector and its mate are one-of-a-kind connectors designed for a specific automotive test application. An FR4 fiberglass sheet may be placed over exposed wiring to protect it from damage and insulate it from the surroundings for high voltage testing.

12 - These 8W8 connectors contain eight coaxial conductors mounted in a DB37-size shell, an unusual arrangement requiring a pair of these custom-built interface boards.

13 - This CB8 board has multiple adapter cables mounted to take advantage of as many test points as possible on this single board. The green wires lead to lug terminals whereas the sheathed wires go to multi-pin mating connectors.

Labels made by a labelmaker may be applied to the board as shown here, or lables handwritten in pencil or pen written on the bare green fiberglass area shown in the upper right.

14 - The adapter cable on this board interfaces a large mixed-signal rectangular connector seen below. In addition to standard signal pins, the connector also has coax and power pins.

Notice the blue, white, and black wires in the upper right corner of the board. These wires break out the coaxial cables into individual conductors that can be soldered to terminal pads on the CB8.

Keep in mind that we need not be concerned with keeping the round shape of coaxial pins or the heavy gauge wire of power pins because the CableEye tester applies no more than 3 mA at 10 V to check continuity and resistance. Dynamic properties (RF impedance, for example) are not tested with CableEye testers.

If you are using our HVX tester to make a 4-wire Kelvin resistance measurement (sensitive to 1 mΩ), an AMPMODU interface rather than this CB8 interface would provide lower resistance for the 1A test current used with 4-wire applications.

15 - This special interface board was build for an automobile manufacturer to test OBD (on-board diagonstic) cables that link a car's system computer to a hand-held computer. Only a single board was needed since the cable has only 16 conductors.

Cables like this have a male connector on one side and a female on the other, so we could easily make this interface by taking a known-good OBD cable, cutting it in half, and wiring each half to the CB8 as shown here.

We attached a felt strip to the front edge of the board to prevent chafing as the adapter cables move around.

 

Application: Automotive

16 - This unusual application involved a panel-mount mating connector for one side of the unit under test, and a cable-mounted mating connector for the other. We mounted a fiberglass plate on standoffs over a CB8 board so the panel-mount connector could be securely attached. Also, with all of the wiring under the fiberglass plate, it is protected from possible flexing or abuse.

 

Application: Automotive

17 - We had just enough pads available on this CB8 board to mount the 62-pin adapter cable you see here.

Mating connectors may come either as cable-mounted connectors as you see here, or bulkhead connectors which would mount directly to the CB8. If a mating connector is available either way, then the method used depends on the customer's test process. While a bulkhead connector mounted directly to the board produces a more compact interface, it may not be appropriate if the test cable consists of heavy-gauge wire or is bulky. Heavy or bulky test cables can apply unreasonable force to the board or tester when attached, or even pull the tester off the workbench.

18 - Customer, CMS has built a series of fixtures, using the CB8, to accomodate the wide range of connectors found in motorsports. Tests performed with HVX series testers.
