North American and CCITT In-Service TIMS & Datalogger
 
Keysight 4948A Features
  • Voice-grade data circuit testing - without disturbing traffic
  • True preventive maintenance
  • Network management information - without special modems
  • Suitable for North American and CCITT environments
  • Test data circuits carrying voice grade modem traffic while they are still in service
  • A simple connection to the data circuit carrying the modem signal, at a voice frequency access point, is all that is required
  • To measure the impairments that have been added between signal generation and the measurement point
  • Measuring Impairments on a Modem Signal: measures the effects of the same line impairments that are measured by a conventional, intrusive TIMS
  • Data Logging: result data can be stored in the test set's own internal non-volatile memory
  • Out-of-Service Testing: transmit and measure on a tone, so it can interwork with tone sources and conventional test sets
  • Transmit & Receive Connectors: WECO 310 & Bantam
