L'explication/l'anotation:Multifunctional source of sinusoidal electric oscillations.
La description détaillée de marque:Is intended for use when measured of communication settings,
channels and paths of transmission systems with frequency multiplexing channels in case of
their adjustment, operation and repair.
the device may be used in-the-fields at a temperature of
- 10ãðàä. With to +50ãðàä. With, as well as in case of relative humidity 95. 98%
in case of 35ãðàä. S.
the device provides:
- step frequency adjustment through 1 Hz;
- stepless frequency sweep with automatic machine. borders tuning of swing with
times of swing 0, 04; 1; 3; 10ñ;
- high installation accuracy of output level;
- possibility of distant frequency control, level, output
resistance and blocking of output signal in 8-4-2-1-code;
- symmetric and êîàêñèëüíûé exits;
- possibility of synchronous frequency tuning with level meter
Ï-326-2;
- high stability to mechanical impacts.
