Page 38: Block Diagram
A/D Circuit Overview Zeta base board “A” models include an analog input circuit based on the LTC1859 16-bit A/D converter, or ADC. The LTC1859 is capable of operating at up to 100,000 samples per second in total, either on a single channel or on any number of channels. -
Page 39: A/D Fifo And High Speed Sampling
The Diamond Systems Universal Driver software provides full support for high speed A/D sampling with FIFO and interrupt support. Please refer to that user manual for operating details. When using Universal Driver software, the interrupt rate is equal to the total A/D sample rate divided by the programmed FIFO threshold, because each time the interrupt service routine runs, it will read out the number of samples equal to the threshold value. -

A/D in the middle. The higher the output impedance of the input signal, the greater the error will be. Conversely, the higher the input impedance of the A/D circuit, the lower the error will be. Zeta base board uses high impedance, ultra-low-offset buffer op amps to boost the input impedance to well over 10 GigOhms (the input impedance is calculated based on the specified input current of 75pA). -
Page 43: Digital-To-Analog Circuit
14.3.1 Overview The Zeta base board data acquisition circuit uses a 16-bit D/A converter. This means that all output voltages are defined by a 16-bit binary number, or D/A code, ranging from 0 to 65535 (2 -1), or binary 0000 0000 0000 0000 to 1111 1111 1111 1111. -
Page 44: D/A Conversion Formula
To minimize the size and cost of the D/A circuit while still providing reasonable performance, the D/A circuit on Zeta base board does not provide calibration features to eliminate these errors. Instead the circuit was designed to minimize the inherent offset, gain, and drift characteristics. The specifications at the end of this manual indicate the worst-case offset, gain, and temperature drift errors in the circuit. -
Page 45: Digital I/O Features
On “A” models, an edge detection circuit is available on port B. The edge detection circuit can be used to notify the processor when a particular event occurs, such as a door opening, a switch being pressed, or a light curtain being penetrated. www.diamondsystems.com Zeta User Manual Rev 1.0 Page 45... -
Page 46: Support For Special Functions
The edge detection circuit on Zeta contains an enable register, a polarity register, and a status register. The programmer can specify which bits will be active with the enable register and which transition to detect on each bit (0 to 1 or 1 to 0) with the polarity register. The status register indicates which bits have seen the specified change since the last time it was read. -
Page 47: Counter/Timer Features
14.5.1 Overview Zeta “A” models include 8 32-bit counter/timers with a wide array of features and programmability. Both up and down counting are supported, and the clock for each counter can be selected from an internal 50MHz or 1MHz clock or an external digital signal. In down counting mode, an optional programmable-width output pulse may be enabled each time the counter reaches zero. -
Page 48: Counter Advanced Features
The DAQ circuit uses counter/timers to control the A/D sample rate for high speed sampling as well as the D/A waveform generator data rate. These operations are managed by the Universal Driver software. Refer to the Universal Driver user manual for details on these advanced features. www.diamondsystems.com Zeta User Manual Rev 1.0 Page 48... -
Page 49: Pulse Width Modulator Features
14.6.1 Overview Zeta “A” models include 4 24-bit pulse width modulator circuits (PWMs). These circuits can be programmed to produce an output square wave up to 25MHz with a duty cycle anywhere from 0% to 100% (these limits are of course DC signals). -
Page 50: Interrupt Operation
The primary host interface for the Zeta base board “A” model data acquisition circuit is the SPI bus. However, the SPI bus does not provide a means to support interrupt operation. Therefore, Zeta base board “A” models provide the ability to generate interrupts on the ISA bus. -
Page 51: 12 "D" Model Daq Architecture Overview
15 “D” Model Digital I/O Zeta “D” models provide 16 digital I/O coming from an I2C I/O expander chip. The digital I/O consists of 16 I/O lines organized as two 8-bit ports A and B. They may be configured with a jumper for either 3.3V or 5V logic levels, and they may also be configured with a jumper for 10K ohm pullup or pull-down resistors. -
