- Very low distortion output
- Fixed and variable sine outputs
 

The Labworks SG-135 Sine Generator/Monitor is a low cost, single-channel, manual sine controller. The SG-135 generates a low distortion sine wave signal suitable for use with electrodynamic shakers of all sizes.

Manual controls feature logarithmic frequency adjustment from 1.0 Hz to 10 KHz in one continuous range and a locking 60+ dB output signal amplitude control. A four digit frequency meter shows the output frequency with 0.2 Hz resolution.

The built in acceleration monitor/bias supply takes either voltage calibrated acceleration signals or integral electronics accelerometers directly and displays the monitored acceleration up to 100 g pk.

The SG-135 is the perfect manual controller for smaller shaker systems, manual calibration stations, engineering evaluation, and general sine testing applications.
