Sage Instruments 930A Communications Test Set Description:

The 930A Communications Test Set combines the functions of a Voiceband Transmission Measurement Set, Return Loss Measurement Set, and a Dial Pulse, Touch Tone (DTMF), and Multi-Frequency (MF) Sender in one lightweight package. The test set also provides Talk Battery to enable the user to talk over the trunk under test.

Sage Instruments 930A Applications:

This test set, while of general purpose in nature, is particularly useful for DEMARC and Central Office testing, as well as PBX and Digital Switch installation testing. It is capable of performing all transmission and signaling tests required at these locations, including those for Feature Groups A – D (Equal Access). The 930A can completely simulate either a PBX or Central Office switch (Local or Toll).

Sage Instruments 930A Standard Features:

The following list shows the standard features and capabilities of the standard 930A (for standard Voice Band applications).

The standard 930A transmission measurements are:

  • Level and Frequency
  • Noise (C-Message, C-Notch, and 3 kHz Flat Weighted)
  • Noise-to-Ground
  • Signal-to-Noise Ratio
  • Return Loss (2- and 4-wire)

The standard 930A signaling and supervision simulation capabilities are:

  • Loop Start (2- and 4-wire, normal and reverse battery)
  • Ground Start (normal and reverse battery)
  • E&M Signaling Types I through V
  • Wink Detection and Timing
  • Delay Dial
  • SX Supervision
  • DP, MF, and DTMF Signaling (parameters may be varied from nominal)

In addition to its supervisory signaling capability, the 930A can establish the talk conditions for transmission testing and has the ability to hold circuits for testing. The basic 930A also includes the ability to store and recall up to 999 tests, receive multi-wink sequences, and perform frequency sweeps such as those used for attenuation distortion measurements.
