The 1662A Logic Analyzer has 100MHz state speed, 64 data channels and four data/clock channels, and both HP-IB/RS232C interfaces. Measurement data is displayed as data listings and waveforms, and can also be plotted on a chart or compared to a reference image. Other key features of the analyzer include Lightweight, passive probes for easy hookup Variable setup/ hold time in the state analyzer External triggering to/from other instruments through rear panel BNCs 4 Kbytes-deep memory on all channels with 8 Kbyte-deep in half channel mode Marker measurements Pre-configured trigger macros. 12 levels of trigger sequencing for state and 10 levels of sequential triggering for Timing Full programmability State/State and mixed State/Timing displays Both state and timing analyzers can use 10 pattern resource terms, 2 range terms, and 2 timer/counters to qualify and trigger on data. In addition, the timing analyzer has 2 edge terms
