*Note: Because of device timing constraints at higher sampling rates, only the first
23 channels of analog I/O are processed when operating the RX8 at 100 kHz.
†Note: See "Realizable Sampling Rates for the RX8" on page 3-9 for a list of
supported sampling rates.
Note: zBus chasis (ZB1PS) required for power and communication.
DB25 Connector Pinouts
TDT Recommends accessing the RX8 I/O via a PP24 patch panel.
Sigma-delta: DC - Nyquist (~1/2 sample rate)
PCM: DC - 7.5 kHz (3 dB corner, 2nd order, 12 dB per
octave)
+/- 10.0 Volts
Voltage In
Sigma-delta: 97 dB (20 Hz - 20 kHz at 10 V)
S/N (typical)
PCM: 80 dB (20 Hz - 20 kHz at 10 V)
