BRIEF TECHNICAL SPECIFICATION
OF
TRANSMISSION TEST SET
SBOM
make Transmission Test Set Model TTS-1 is made
for testing of telephone channels in audio frequency
range from 300Hz to 4,000Hz. Parameters such as
level, Gain, Attenuation, Frequency response etc.
can be easily measured by the set. |
Model
No. TTS-01
|
|
The
set consiststs of a self frequency generator and
a level meter. The frequency and level of generator
can be selected by switches on the panel. The
output has 600 Ohms output impedence.
The
meter has high impedence of hook which can be
switched to 600 Ohms. The meter shows level in
dbm. 3 ranges are provided for level measurement.
