J2114A High CMRR Isolation Amplifier – Ground Loop Breaker
The J2114A is a solid-state high CMRR (> 100dB) Amplifier or ground loop isolator, that provides the BEST isolation for low impedance measurements. The J2114A removes the groups loops associated with VNAs and Oscilloscopes which occur in many different types of test setups.
Key Features
- Enables measurement of micro-ohm impedances
- Greater than 100dB isolation
- Eliminates DC ground loop down to DC
- Works up to 10MHz
- Supports the 2 Port Shunt Thru impedance measurement required for Power Distribution Networks (PDNs)
- Works with all types of test equipment to eliminate ground loops, such as Network Analyzers, Oscilloscopes and Spectrum Analyzers
- Excellent CMRR performance
- Popular for oscilloscopes – isolate probe grounds – J2114A is optimized for pulse response
- Perfect for ultra-low impedance PDN measurements
