Section 1 - General Description Cutoff Frequency Accuracy: ±1%, 0.5Hz to 50kHz; ±2%, 50.1kHz to max fc; ±5%, 0.03Hz to 0.5Hz (option 002, ±5%, 0.003Hz to 0.5Hz). Relative Gain at fc: –3dB, Butterworth; –12.6dB, Bessel. High-Pass Bandwidth (0dB Gain): fc to 2.5MHz. Stopband Attenuation: >80dB. Insertion Loss: 0dB; ±0.2dB. Pre-Filter Gain: 0dB, 10dB, 20dB, 30dB, 40dB, 50dB; ±0.2dB. Post-Filter Gain: 0dB to 20dB in 0.1dB steps; ±0.2dB. Input Coupling: ac (0.16Hz) or dc. Wideband Noise (referred to input, 2MHz BW detector): min. gain, 60dB to 10kHz; >50dB to 99kHz. Sensitivity: 3mV peak with 70dB total gain for 10V peak output. Maximum Input: æ10V peak at 0dB gain, reduced in proportion to gain setting (to 500kHz LP). Impedance: 1 megohm in parallel with 100pf. Coupling: ac or dc. Maximum DC Component: ±100V in ac coupled mode. Output: Maximum Voltage (o.c.): 7Vrms to 200kHz; 3Vrms to 500kHz; 1Vrms to 1MHz. Impedance: 50 ohms. DC Offset: Adjustable to zero volts. Harmonic Distortion (1V output): –80dB (0.01%) to 10kHz; –60dB (0.1%) to 100kHz.. Wideband Noise (referred to input, 2MHz BW detector): 250mVrms min. Gain; 25mVrms max. gain. 1-2
Section 1 - General Description DC Stability (RFI): Typically ±10mV/°C. Crosstalk Between Channels: >85dB below full scale with input source
