The classic example of Signal this is evoked-response recording; here segments of brain activity are correlated with recurrent stimuli, in order to extract responses buried in the noise. -
Page 20: Inputs And Outputs
Input and outputs The following points deal with physical and electrical aspects General of Power1401 connectors, rather than their electronic function. The outer sleeves of the front-panel BNCs, and the metal shells Mains earth of the various rear-panel connectors, are robustly connected to the metalwork of the case and, via the earth pin of the DC inlet and the earth leads of the power brick, to mains earth. -
Page 21: Waveform Input
Inputs and outputs There are sixteen waveform input channels on a standard Waveform input Power1401. Eight channels are available through front-panel BNC connectors, labelled , and eight through the ADC Inputs rear-panel D-socket. All inputs pass Analogue Expansion through ferrite chokes that block high-frequency noise. The working input range of the ADC (and the DAC outputs) is ±5 V or ±10 V, as selected in the TRY1401 utility;... - Page 22 Inputs and outputs The front-panel waveform input channels each have an ADC LEDs associated yellow LED. They are controlled by software command and typically turn on when the channel is in use. The trigger-input LED flashes or blinks on detection of an Trigger LED active-edge transition at the input.

On an unexpanded Power1401 it accommodates analogue ADC input channels 8 - 15 and DAC channels 2 and 3. (For connector rear-panel channel numbering on expanded units, see below.) The ten signals are on the bottom row of the D-socket, and each has its own ground return on the top row. -
Page 25: Clocks
Inputs and outputs The Power1401 has five clocks, used for timing and counting Clocks external pulses (clocks 0 and 1), generating general-purpose timing pulses (clock 2), controlling waveform output (clocks 3 and 4) and controlling the waveform input sampling rate (clock 4). - Page 26 Inputs and outputs The frequency synthesizer is an internal device capable of Frequency generating frequencies that cannot be obtained by simple synthesiser integer division of the 25 MHz crystal oscillator. An example of this would be the 44·1 kHz sampling frequency widely used in digital audio applications.

Page 28: Digital Input And Output
Front-panel digital-output LEDs simply reflect the state of the bits, being lit whenever their bit is set (high). The Power1401-3 is provided with a 1-Wire port on pin 22 of The 1-Wire port the input connector. This allows bidirectional communication down a single wire (plus ground) to one or more devices, which are also powered from the same wire. - Page 29 Inputs and outputs Digital data transfer between the Power1401 and external Digital I/O equipment can optionally be synchronized by pairs of handshake protocol handshake signals. There are separate pairs for each byte. The polarities of all signals can be set independently by software. The example that follows is typical.
