Combined with SG-4104/4105, DG-8000 and other signal generators, it can amplify up to 24Vp-p (at 50Ω) and 48Vp-p (open).

Features

·         High output
48Vp-p (when the output end is open), 24Vp-p (when 50 ohm termination) Combined with a commercially available signal generator, you can easily obtain the required voltage for each field.

·         External AM modulation input function. Easy realization of PAM modulation
AM modulation can be added to the main signal simply by inputting a signal to the AM modulation input.
Furthermore, by using the offset function together, the DC component of the AM (pulse amplitude modulation) signal can be changed very easily. PAM has been applied to refrigerators and washing machines in the field of home appliances, and further applications are expected in the future.

·         LO-Ω output mode
You can switch between 50Ω output and LO-Ω output. By using the LO-Ω output mode, it is possible to supply a stable signal to the load while maintaining the voltage swing within the output current range even if current flows through the output load.

·         Wideband 1MHz A
maximum amplitude of 48Vp-p can be maintained while maintaining a 1MHz band. Very effective in the mechatronics field.

Use

·         Signal source for driving Hall element sensors used in automobiles, etc.

·         Power supply for small signal semiconductor devices

·         Small battery emulation

·         Signal source for driving power devices (small motors, positioning motors, etc.)

·         Emulation signal for PAM control

PAM waveform generation example

The input of SG-300 is PWM signal (CH1) of 20kHz cycle. Here, if a 50Hz sine wave is input to the AM modulation input of SG-300 and AM modulation is applied, a PAM signal with a modulation frequency of 50Hz will be obtained.
