It has a useable frequency range from 40 Hz to 10 kHz at full power or from DC to 100 kHz small signal; the harmonic distortion is hereby very small. The power amplifier can tolerate temperature and supply line variations while maintaining excellent stability. Thereby, the product can be used as a voltage generator with low output impedance and a flat voltage frequency response, or as a current generator with high output impedance and a flat current frequency response. The maximum RMS output-current limit is adjustable. For standard application, we recommend using the product in voltage mode. Page 1 of 2 SPEKTRA
