Sample and Hold Acquisition for high speed, high accuracy
The LeCroy Model LG8252 is a 32-input ADC intended for use in general pur- pose voltage-monitoring applications. The Model LG8213 is a 16-channel ver- sion with identical characteristics unless otherwise noted. The >10M Ohm inputs of the LG8232 respond to voltages over a 10-volt range, converting them to proportional 12-bit digital data words. An on-board switch provides the choice of a unipolar mode, 0 to + 10 volts, or a bipolar mode, -5 to + 5 volts. The differential inputs suppress common mode signals and noise.
The voltage levels at the 32 inputs on the front panel connectors are converted sequentially, requiring a maximum of 60 microseconds/channel for conversion and storage in random access memory. During readout the addressed 12-bit data word is placed on the Dataway without any interference with a store cycle, should one be present (asynchronous readout). In the Continuous Scan Mode each channel of the LG8232 continuously updates its memory every 2 ms (1 ms for the LG8213).
