The 38 provides a tunable frequency range from 0.03Hz to 1MHz in the low-pass mode and 0.03Hz to 300kHz in the high-pass mode. Both modes are extended down to 0.003Hz with the 002 option. The frequency response characteristic is either maximally flat (Butterworth) for clean filtering in the frequency domain, or linear phase (Bessel) to provide superior pulse or complex filtering is operator selectable. -
Crosstalk Between Channels: –85dB below full scale with input source <50 ohms. -
Low-Pass Phase Match Between Channels: ±2° to 500kHz, ±5° to 1MHz. Only for cards purchased at the same time. -
High-Pass Phase Match Between Channels: For fc £100kHz, ±2° for fsig £500kHz, 2° times fsig/500kHz for fsig to 2MHz; for fc >100kHz, ±5° for fsig £500kHz, 5° times fsig/500kHz for fsig to 2MHz. Only cards purchased at the same time. -
Gain Match Between Channels: ±0.2dB max. to 100kHz. -
Switch: For selection of Input, +(in phase), Differential or –(inverted). -
Input/Output Connectors: BNC. -
Power: 15 watts.
