In the measurement electronics, the important role played by the signal generator, the circuit during the testing, to test the feasibility of the actual circuit generating a test signal by using a signal generator desired, signal generator may be replaced the actual signal, for testing, greatly reducing the link test link signal source generates a signal in accordance with the demand by the signal generator.
Currently on the market for the practical problems of conventional low-voltage output signal source, with a load capacity is weak, can not obtain high-power ultrasonic transducer capacitive load, Aigtek developed to a high power amplifier is designed, the maximum output of 160Vp-p (± 80V) voltage, 320W power, bandwidth DC-1MHz.
For example, when doing NDT experiment, the electromagnetic ultrasonic NDT inspection technique is based on the principle of electromagnetic induction, electromagnetic acoustic transducer coupling medium does not need to be achieved at a high temperature, high speed detecting operation conditions, in non-destructive testing field much attention. Electromagnetic Acoustic detection device as the core system, the ultrasonic signal generated is small, power is required to drive the circuit, which requires a high voltage power amplifier to achieve this function.
ATA-4014 Xi'an Aigtek has introduced a high-pressure high-voltage bipolar power amplifier, he has a high voltage, high current, wide frequency, low price, etc., may use this amplifier is no distortion in the waveform while increasing voltage, it avoids the internal protection circuit overcurrent, overvoltage test, the resistance of the input and output can be switched two steps, matching more capacitive, inductive and resistive load.
ATA-4014 is capable of processing the signal from the DC to DC up to 1MHz, a voltage amplification type amplifier is a bipolar embodiment of a high-speed, wide-band, high voltage output. 4-quadrant voltage and current can be positive and negative output, capable of operating stably as a piezoelectric element and a capacitive load or inductive load such as a coil.
Signal generator after the power amplifier using a high pressure measurement in real time oscilloscope waveform signal generator generates the signal magnitude and frequency, in the case of testing a circuit to meet the power requirements of the indicators, with the capacity to solve the problem of weak, further analysis performance test circuit. Signal generators and high-voltage power amplifiers are widely used in the medical field, military field, space technology and other fields, plays an important role in the field of electronic measurement technology.
Aigtek high voltage power amplifier can match any brand of a signal generator, the output voltage amplitude of the signal source is only about 10Vpp-20Vpp, the user is doing a lot of testing is enough voltage and power, coupled with the power amplifier can guarantee undistorted signal a case where the voltage is raised to the maximum 1600Vpp, 1000W power, amplified in a certain frequency range waveform distortion.
