Does a signal generator produce current?
The function of a signal generator is to produce alternating current (AC) of the desired frequencies and amplitudes with the necessary modulation for testing or measuring circuits. It is important that the amplitude of the signal generated by the signal generator be correct.
What is a high current amplifier?
A “high current amp” is an amplifier that has a significant amount of current that it can deliver, largely because the amplifier 1) has a very large power supply, and 2) has high quality output transitors capable of using that power to deliver the signal to the speakers.
How to adjust the frequency of a waveform generator?
Adjusts the duty cycle or symmetry of the displayed waveform. Turns the frequency sweep mode on and off and allows selection of a linear sweep or logarithmic sweep. After pressing this button, the adjustment knob (control 2) will adjust the output signal’s frequency.
What is the total current of a waveform amplifier?
The total current is the sum of the two waveform amplifiers current combined. The two high-voltage function generator amplifiers must be isolated each with a 0.3Ω to 1.0Ω series resistor. Okay to use higher resistance for higher voltage output.
What are the features of an arbitrary waveform generator?
Today’s basic units are capable of sine, square, and triangle outputs from less than 1 Hz to at least 1 MHz, with variable amplitude and adjustable DC offset. Many generators include extra features, such as higher frequency capability, variable symmetry, frequency sweep, AM and FM operation, and gated burst mode.
What is the output voltage of a pulse generator?
Most function generator, pulse generator, and arbitrary waveform generator output voltage are limited to about 10V. Function generator output resistance is typically 50 ohm, making it not suitable driving low resistance (high current) load.
