The 466A AC Amplifier is ideal wherever low distortion, stability, wide frequency range, and portability are desirable; and it may be used to increase the sensitivity of voltmeters and oscilloscopes, since its gain is accurate and stable. Frequency Response: ?0.5 dB, 10Hz to 1MHz down 3dB, or less at 5Hz and 2MHz Gain: 20 dB (x10) or 40 dB (x100) ?0.2 dB at 1000 Hz Output Voltage: 1.5 V rms across 1500-ohms Output Current: 1 mA maximum
