Low-frequency signal generator G3-118 (G3118, G3 118)
Low-frequency signal generator G3-118 RC-type low-frequency discrete-frequency unit within each of the five subbands. It is possible to continuously adjust the frequency within the discretion LSB.
Block diagram of the signal generator provides precise forms the entire frequency range. The generator has an effective system of stabilization of the output voltage, which is regulated in a wide range of discrete and smoothly.
The instrument low-frequency signal generator G3-118 is a passive low-frequency notch filter into a number of discrete frequencies, which provides for the use of 114 series spectrum analyzer measurement of ultra low harmonic coefficients.
Frequency response 10Hz-200kHz
Setting the frequency is discretely on the five sub-bands: 10Hz-100Hz (over 0.1 Hz) 100Hz-1000Hz (via 1Hz), 10000 Hz, 1000 Hz (in 10 Hz); 10000Gts-100000Gts (via 100Hz) 100000Gts-200000Gts (through 100 Hz).
