High frequency, high current testing of very low impedance loads
LPA05A & LPA05B laboratory power amplifiers provide wide bandwidth signal amplification at up to 8A peak, extending the range of industrial and laboratory applications into which the LPA series can be used.
Designed originally for use with the PSM range frequency respsonse analyzers, the LPA05 laboratory power amplifier can also be used anywhere where there is a need to boost a signal either in voltage or current up to 1MHz.
They combine DC accuracy with wide bandwidth to faithfully reproduce complex waveforms, driving loads that may be capacitive, inductive or resistive.
Optionally, the DC component can be eliminated with AC coupling, or can be reduced with AC+(DC) coupling. To limit high frequency noise, the input bandwidth can be reduced with a linear phase, 2nd order, low pass filter for low frequency applications. A common application for the laboratory power amplifiers is in situations where is a requirement for impedance measurement of a device under high voltage bias or high current bias conditions, in these applications the combination of a PSM1700, PSM1735 or PSM3750 + LPA Laboratory Power Amplifier + HF Current Shunt form a high power impedance measurement system.
