**What is Multiple Bus Architecture?**

With MBA switching, functional testing is simplified by connecting power sources and other devices directly to the UUT through a single adapter cable rather than the “Y” cable required with standard switching and separate EE/LM points.

MBA switching can connect your product to DC and AC power supplies, load panels, potentiometers, and indicator LEDs.

**Determining When to Use MBA**

- When you need to test complex assemblies with multiple active devices
- When you have a large mix of products to be tested that require EE/LM activation

**The MBA Difference**

- Simpler universal adapter cables – eliminate complicated spider cables required to separate EE/LM connectors 
    - Reduce adapter cable inventory and material costs
- Each test point is an EE/LM point and a standard switching point
- Easily accommodate changes to the UUT by changing the test program, not the adapter cables
- Provides maximum versatility when combined with DIT-MCO’s Adapter ID System
