Explanation/Annotation:For determination of channel and paths of systems of connection with frequency multiplexing
in case of their adjustment, operation and repair in the range of frequencies
0, 2. 2100 kHz.
Detailed model description:The Ï-326-4 device may be used in-the-fields in case of
temperature from - 10 degree. With to +50 degree. With, as well as in case of relative
moisture 95. 98% in case of 35 degree. S. the device keeps its parameters of po
le of temperature effect from - 50 degree. With to +60 degree. S.
device together with measuring generator of Ï-326-1 and general-purpose
level meter of Ï-326-2 provides:
- measurement of transducer attenuation;
- measurement of transient attenuation;
- measurement of working strengthening;
- attenuation measurement of inconsistency;
- attenuation measurement of asymmetry.
