J-Testr+ Midi
|
|
The J-Testr+ Midi incorporates a J-Testr mounted inside of a medium sized fixture with a base foot print of 465mm x 500mm (465mm x
|
515mm with extended handle). Even though not as small as the J-Testr+ Mini, these dimensions still make the J-Testr+ Midi easily portable and compact enough to be used as part of an inline production process.
The fixture UUT probe plate is fully inter-changeable and supports PCB sizes up to 285mm x 240mm with a recommended maximum of 2000N contact force (up to 1000 pins). This inter-changeability allows ultimate flexibility such that the same tester setup can be used for multiple UUTs, thus maximising the customer's return on investment. The J-Testr+ Midi can include a horizontal ‘interim pylon connection’ between the inter-changable unit and the main fixture frame. The pylon connection supports up to 480 “EZ-Wired” compatible connections, or up to 850 using more traditional connection methods. The pylon interconnect can support other connection types including high power, optical, RF, etc. For more information on the ‘interim pylon connection’ please contact Eiger Design on [email protected] |

The J-Testr system itself is mounted centrally at the very rear of the J-Testr+ Midi fixture base box. This allows the J-Testr rear connections, including the customisable interposer connector edge, to be available at the back of the fixture for easy external access. This allows users the convenience of placing connections to the outside of the test system directly from the J-Testr interposer, e.g. Debug ports, USB connection, etc.

|
A rectangular slot is provided at the top rear of the J-Testr+ Midi, directly above the J-Testr's interposer, to allow cables to exit the fixture base box.
This is particularly useful if external equipment is required to be connected or for connection access to the top of the fixture, e.g. for a top mounted LED analyser system. If the slot is not used a cover plate is provided. |
|
The front slope of the J-Testr provides an area such that the user can add LED indicators, such as pass/fail, or buttons/switches for direct user interaction with the tester. The plate is fixed/removed with 6x M3 bolts and CAD data is available for user to create custom panels from ‘front panel’ vendors like Schaeffer AG located in Germany

The J-Testr+ Midi base box has a 100mm x 100mm VESA mount on the top left side to enable the direct mounting of miniature computers such as the Gigabyte BRIX or Intel NUC models. This allow the the computer to effectively become a permanent part of the test fixture as well as saving more valuable bench space.
Extra fixings are also available at the rear of the fixture base box to attach brackets to mount ethernet hubs or even a PC monitor* 
* Requires a custom designed bracket.

The J-Testr+ Midi comes with the option of an RF chamber and includes standard mounting points for a Min-Circuits FCPM6000 power meter/frequency counter within the fixture base box. This allow the J-Testr+ Midi to be made into a full RF testing solution, for applications such a Bluetooth, ZigBee and WIFI, with the ability to test RF output power and RF frequency all within an ultra-compact RF test system.
