Knowing the signal Input signal: Voltage Current Temperature Speed Pressure Sensors: Transducer /Conditioner Thermocouple / RTD Encoder Strain gauge Data type: Voltage Current Counter / Frequency

Knowing the signal – Cont. Analog Input Analog Output 25 KHz to 30 MHz 12 to 16 bits 8 to 32 channels Isolated input 12 to 16 bits Voltage output Current output Isolated Output Digital Input Digital Output 24 to 144 bits TTL and Isolated input Vector Interrupt Counter Function 01010 10111 10001 24 to 144 bits TTL, Relay and Isolated output Timer Function 10111 10011 00100 Here are the signals at a glance: Signal Conditioning Relay Output Amplifier gain up to 1000 Thermocouple, RTD Multiplex up to 256 channels Signal Isolation Rating form 30 VDC to 250 VAC Form A, Form C and SSR Opto-22 compatible

Analog Input More accurate Almost 16 times smaller!! A/D Resolution: 12 bits - 2resolution = 212 = 4,096 levels 16 bits - 2resolution = 216 = 65,536 levels Each level also known as Least Significant bit (LSB) represent how small a voltage level can be detect in a specific full scale range. For 12 bits AI, input range is +/-10V: Resolution = 20V / 4096 = 4.88 mV per division For 16 bits AI, input range is +/-10V: Resolution = 20V / 65,536 = 0.305 mV per division Input range is ±0.005V (PCI-1710HG): Resolution = 0.01 / 4096 = 2.44μV Almost 16 times smaller!! More accurate

Analog Input – Cont. ! Sampling rate: 1Hz, 100Hz, 1KHz, 100KHz, 250KHz, 1MHz, 30MHz Nyquist sampling theorem: Sampling rate >= 2 x signal bandwidth Measured signal Sampling rate ! Multiplexing means that the sampling rate is shared across all active input channels. For example, 100KS/s / 16 channels = 6.25KS/s per channel !!! But PCI-1714 is capable of up to 30MS/s per channel – 4 A/D converters

Analog Input – Cont. Differential has advantage of immune to Other spec: Number of channels – 4, 8,16, 32 Input Ranges - Bipolar (0-0.01, 0-2.5, 0-10, etc) - Unipolar (±10, ±5, ±1, ±0.005, etc) Gain – High gain ( PCI-1710HG/L) , programmable gain FIFO Buffer Size – 1K, 4K, 32K (PCI-1714) samples Data transfer mode – Software, Interrupt transfer, DMA transfer (BUS master) Trigger mode – Software, Pacer, Pre-Trigger, Post-Trigger, Delay-Trigger, About-Trigger Auto-calibration - The built-in calibration circuitry corrects gain and offset errors in analog input and analog output channels eliminating the need for external equipment and user adjustments. Board ID Single Ended / Differential: CH0 CH1 CH14 CH15 + - CH0H CH1H CH0L CH1L Differential has advantage of immune to induced noise on the two input terminals. Since these two signals are subtracted from each other, rather than one terminal to ground, hence, the term is differential.
