We have designed a holder to hold a Saleae logic analyzer, for use with the PCBGRIP system. The idea was to design a holder that would hold the Saleae logic analyzer against the OpenBeam used in the PCBGRIP system, providing the following benefits:
Here is a photo of the holder holding a Saleae Logic 8:
Open source models for the Logic 4, Logic 8, Logic 8 Pro, Logic 16 Pro can be found on Thingaverse. If you do not have access to a 3D printer, there are 3D printing services, such as Shapeways (no affiliation) which you can upload the models to and they can print them for you.
Here is a photo of the Saleae Logic 8 being held on the PCBGRIP system:
The Saleae analyzers are a very well made product and are encased in a durable anodized aluminum case (we are especially partial to the red anodized version !). The analyzers are relatively small, making them ideally suited for mounting on the PCBGRIP system. For those situations where it is difficult to attach the mini-grippers that come with the Saleae analyzer to the location to be tested, the PCBGRIP system can be used to hold other testing components. One of the simplest solutions is to hold a pogo pin against the contact you want to test. To isolate the pogo pin, we first place some heat shrink tubing over the pogo pin:
The pogo pin can then be held with one of the PCBGRIP components. In this picture, a Variable Tee is being used to hold the pogo pin:
The pogo pin can then be used to test a pad (or other component) and the pogo pin is connected to a mini-gripper (supplied with the Saleae logic analyzer) and lead from the Saleae logic analyzer:
Rotating the PCB and holding it vertically, easily allows both sides of the PCB to be probed. With the holder keeping the Salaea analyzer in the same relative position to the PCB, the test leads do not become tangled and are not pulled off the PCB:
