These SMA adapters allow seamless integration of your Ossila micromanipulator with a range of measurement instruments. Start testing immediately by ensuring your systems are compatible with a common grounding scheme. These adapters allow for connections between:
- SMA - BNC Cables (Differential Interface)
- SMA - Banana Cables (Micromanipulator SMA to Banana Adapter)
- SMA - Triaxial Instruments/Cables (Triaxial Adapter)
The differential interface can accommodate up to three inputs from the Ossila Micromanipulator with dual channel outputs, ideal for interfacing with the Ossila Source Measure Unit. The Ossila Micromanipulator SMA to Banana Interface can accommodate 4 SMA inputs and 4 banana plugs (Force HI, Force LO, Sense HI, Sense LO) to achieve a true four-wire measurement. The triaxial adapters provide a simple SMA-to-Triaxial conversion for a single plug.

Grounding And Shielding
Differential Interface
The differential interface uses a common grounding scheme. The shields of all connected BNC and SMA cables are electrically continuous and referenced to a common point. This allows a third micromanipulator to serve as a ground reference. By connecting this probe to the COM port, the reference potential is distributed across the shields of the entire assembly.
Micromanipulator SMA to Banana Interface
Because the SMA shields on Ossila Micromanipulators are electrically isolated from the probe tip, leaving them floating would result in the cable shield acting as an antenna. This creates a risk of capacitively coupling environmental noise into the signal path.
To mitigate this, the adapter implements a centralized grounding configuration at the interface. The shields of all connected coaxial cables are shunted to the Force LO terminal. By referencing the shields to the measurement return path (Force LO), the setup ensures that the cable shields act as an effective Faraday cage. This preserves signal integrity for un-guarded measurements without introducing ground loops.
SMA to Triaxial Adaptors
The Triaxial adapters use the Type 2 Shielding Scheme. Type 2 shielding ensures operator safety when transitioning from triaxial to coaxial cabling. This connects the Triaxial Outer Shield to the Coaxial Shield, while the Triaxial Inner Shield (Guard) is terminated at the adapter.
While active guarding is standard for ultra-low current measurements, extending the Guard potential onto the shield of a coaxial cable creates a significant shock hazard. The Type 2 scheme eliminates this risk. Although the active guard stops at the adapter, this configuration maintains continuous EMI shielding via the chassis ground. It is the standard, safe protocol for interfacing coaxial probes with triaxial instruments.
