Applications

Communication Pulse Shape or Eye Pattern Testing
Electrical Communication and Video Signal Interface for 50 Ω Terminated Instruments

The AFTDS Differential Signal Adapter and the AMT75 75 Ω Adapter provide an effective means for 50 Ω terminated instruments to connect to, and analyze differential and high speed electrical communication signals, as well as video signals.

Both adapters are rugged and have the TEKPROBE interface, which provides convenient auto-scaling of waveforms on Tektronix TDS Series oscilloscopes. Also, the low VSWR (Return Loss) performance minimizes measurement errors commonly associated when interfacing with complex electrical signals.

Ideal for use in pulse shape compliance testing of high speed electrical communication signals.
