Designed as a direct but improved replacement for the obsolete American Reliance 186T and 188T.

   The Convex 806F TIMS Transmission Test Set is a basic telecom instrument designed to replace the 186T and 188T Transmission Impairment Measuring Sets. It measures LEVEL, NOISE, NOISE-with-TONE, SIGNAL / NOISE RATIO, NOISE-to-GROUND, and FREQUENCY in accordance with IEEE Standard 743-1984. It has the basic features needed to trouble- shoot, characterize and qualify transmission facilities for services ranging from Plain Old Telephone Service (POTS) to Digital Subscriber Line (DSL). It is packaged in compact portable unit and may be rack mounted using attachable mounting ears. All metal construction permits heavy use.

   The 806F is accurate, rugged and economical. CONTROLS Front panel controls are simple and utilize large bright LED displays and indicators which are grouped for ease of use. The 806F also comes with software that runs under DOS, or a DOS window under Windows Operating Systems. The PC communicates with the test set through an RS-232 Port which is locatedon the side of the test set. The LEVEL and FREQUENCY measurements operate from 20 Hz to 110 kHz. LEVEL and NOISE readings are fully auto-ranged. LEVEL is measured in dBm (power relative to 1 milliwatt). NOISE is measured in dBrn (power relative to 1 picowatt) or dBm.

   NOISE is measured with one of four weighting filters. Noise-to-ground (or Power Influence) is measured directly using standard test leads. A 1010 Hz Notch Filter is provided to measure NOISE-with-TONE, Signal to Noise Ratio, or Signal to Total Distortion Ratio.

Filters

   The C Message Filter is provided to frequency weight noise in terms of its interference with voice traffic related to Plain Old Telephone Service. The 3 kHz Flat Filter weights noise as it relates to VF modem or fax traffic. The 3 kHz Filter is also used to detect noise associated with power line or 20 Hz ringing energy. The 1010 Hz Notch Filter is used in conjunction with weighting filters to measure Noise with Tone or S/N Ratio. The 15 kHz Filter is used to weight noise as it impacts broadcast quality audio and other wide band transmission. The 50 kBIT Filter weights noise as it impacts Digital Data Service (DDS) and Digital Subscriber Line (DSL)

Filter Application
  • C MSG POTS Voice Traffic
  • 3 kHz POTS power line / ringing interference
  • 15 kHz Modem Traffic / Program Noise
  • 1010 Notch POTS S/N Ratio / Noise or S/N on PCM
  • 50 kBIT DDS and DSL

Accesories

   The 806F includes a rechargeable, lead - acid, battery and padded canvas field case. The battery powers the test set for 8 hours and can be recharged while in operation or when convenient. The field case has a pocket which includes the following accessories: two miniature phone plug / clip test leads, an Operating Manual, PC Software, and AC Charger. The 806F comes as a complete, road ready, kit.
