Agilent/Keysight E7580A

The Keysight E7580A ProBER 2 is a handheld test set for bit error rate (BER) testing and signal quality measurements on 2 Mb/s and 64 kb/s digital circuits. It delivers comprehensive diagnostics to isolate frequency, level, pulse shape, and jitter problems on PDH signals, enabling rapid installation and maintenance troubleshooting.
