The model 632 Logic Analyzer has been designed to provide a high performance, low cost instrument, capable of trouble shooting synchronous logic systems. The analyzer has sixteen data channels, two qualifiers and a clock input, which, coupled with its integral hexadecimal display, allows it to be used, ‘free standing’, in the analysis of microprocessor systems. The unit also provides oscilloscope outputs, which are used to generate the familiar timing diagram. These can be used to view the data flows for pattern comparison, or to inspect binary data.
