Low-frequency signal generator G3-117 (G3117, G3 117, GB-117)
Low-frequency signal generator G3-117 is used to work in automated systems with a record of results for one-and two-coordinate recorder.
Advantages of the generator - a smooth overlap the entire frequency range, the automatic frequency control devices and the availability of compression.
For an accurate reading of the set output frequency low-frequency signal generator unit G3-117 uses a built-ESCH. Measuring the output napryazheniyageneratora, input voltage devices compression and compression level is an integrated electronic voltmeter.
Operation of the unit low-frequency signal generator G3-117 is based on the principle of beating the two RF signals. Frequency tuning is performed using a DC voltage in one of three ways:
- From manual control of frequency;
- The built-in generator electronic scanning;
- From an external timebase.
The development can be carried out in a linear or logarithmic. The built-in scanner unit low-frequency signal generator G3-117 provides single and multiple scan frequencies between the regulated limits the frequency with the ability to start, stop and change the direction of the sweep.
Compression apparatus bass instrument signal generator G3-117 is used to automatically adjust the level by a signal from an external sensor to a special exit.
Technical characteristics of the instrument low-frequency signal generator G3-117:
- 20Hz-2kHz, 20Hz-20kHz, 20Hz-200kHz - linear scale;
- 20Hz-2kHz, 20Hz-20kHz, 200Hz-200kHz - logarithmic scale;
