A 5OOA, 5OOl?, 556 mainframe. Up to nine AOM5 modules or system strobe feature, supported by two levels of data can be used in these systems for a maximum of 36 analog latching in the D/A converter, allows all D/A channels to output channels. The AOM5 can also be used in the option be updated simultaneously. slot of the Model 570 or 575 for up to 6 analog output channels. TheAOM5 D/A converters offer 13-bit resolution (12 data The AOM5 uses the voltage reference which is a part of the bits plus a sign bit). Four output ranges can be independ- system A/D converter circuitry.

Maximum nonlinearity This requires that the optional on-board voltage reference is fl.O24%. be populated on the AOM5. This reference circuitry is ex- plained later in this manual under the topic "Using the On- board Voltage Reference". The AOM5 analog output circuitry has a 5~s settling time, and can theoretically achieve output update speeds of 2OOkHz. However, the speed of the computer limits the rate at which successive output values can be written to the Software Compatibility module, with a typical speed being about 6OkHz for a 1OMHz 80286-based computer. Keithley's KDAC500 software fully supports the AOM5. If you are using third-party software, be certain that the software is compatible with the AOM5. High-speed operation is supported in Keithley's KDAC500 software by the ANOUTQ (ANalog
