Anti-aliasing filters
The right anti-aliasing filter is essential for protecting your signal-of-interest
Single-channel anti-aliasing filters
These are passive LCR-filters with pseudo-elliptic characteristics. They are optimized for a low-impedance feed (50 Ω), and a high-impedance load (above 10 kΩ), and have a flat group delay through the passband. The high stopband attenuation releases the full potential of today’s high-resolution acquisition systems.
Single channel, fs ≥ 450 kHz, fmax = 125 kHz
Designed for a sampling frequency of at least 450 kHz, and bandwidth of your signal contents up to 125 kHz. Recommended is fs = 500 kHz for digitizing signals up to 125 kHz.
Single channel, fs ≥ 180 kHz, fmax = 50 kHz
Designed for a sampling frequency of at least 180 kHz, and bandwidth of your signal contents up to 50 kHz. Recommended is fs = 200 kHz for digitizing signals up to 50 kHz.
Single channel, fs ≥ 90 kHz, fmax = 25 kHz
Designed for a sampling frequency of at least 90 kHz, and bandwidth of your signal contents up to 25 kHz. Recommended is fs = 100 kHz for digitizing signals up to 25 kHz.
Single channel, fs ≥ 45 kHz, fmax = 12.5 kHz
Designed for a sampling frequency of at least 45 kHz, and bandwidth of your signal contents up to 12.5 kHz. Recommended is fs = 50 kHz for digitizing signals up to 12.5 kHz.
Dual-channel anti-aliasing filters
The filters have the same characteristics as the single-channel models, but have two channels for the many applications that require acquisition of two signal components.
Dual channel, fs ≥ 450 kHz, fmax = 125 kHz
Designed for a sampling frequency of at least 450 kHz, and bandwidth of your signal contents up to 125 kHz. Recommended is fs = 500 kHz for digitizing signals up to 125 kHz.
Dual channel, fs ≥ 180 kHz, fmax = 50 kHz
Designed for a sampling frequency of at least 180 kHz, and bandwidth of your signal contents up to 50 kHz. Recommended is fs = 200 kHz for digitizing signals up to 50 kHz.
Dual channel, fs ≥ 90 kHz, fmax = 25 kHz
Designed for a sampling frequency of at least 90 kHz, and bandwidth of your signal contents up to 25 kHz. Recommended is fs = 100 kHz for digitizing signals up to 25 kHz.
Dual channel, fs ≥ 45 kHz, fmax = 12.5 kHz
Designed for a sampling frequency of at least 45 kHz, and bandwidth of your signal contents up to 12.5 kHz. Recommended is fs = 50 kHz for digitizing signals up to 12.5 kHz.
