The Sage 930A Communications Test Set combines the functions of a Voice band Transmission Measurement Set, Return Loss Measurement Set, and a Dial Pulse, Touch Tone (DTMF), and Multi-Frequency (MF) Sender in one lightweight instrument.
The 930A also provides Talk Battery to enable the user to talk over the trunk under test. The 930A is particularly useful for DEMARC and Central Office testing, as well as PBX and Digital Switch installation testing
