The HP 1652B and HP 1653B logic analyzers are general-purpose logic analyzers with built-in oscilloscopes. If you’re familiar with the HP 1652B/HP 1653B or any HP digitizing oscilloscope, you’ll recognize many features that you’ve grown to know and love. If you’re new to our analyzers and oscilloscopes, the HP 1652B/HP 1653B is easy to get to know. The only differences between the HP 1653B and the HP 1652B, are the number of data channels and the speed of the state analyzer. The HP 1652B has 80 data channels and 35 MHz state analysis while the HP 1653B has 32 data channels and 25 MHz state analysis. Both analyzers have 100 MHz timing analysis along with 100 MHz single-shot and repetitive (repetitive single-shot) oscilloscope measurement capabilities. Because the differences are small between both instruments, they use the same set of manuals. Some of the key features shared by both the HP 1652B and HP 1653B are listed below: • Transitional or glitch timing mode on all channels. • Simultaneous state/state or state/timing modes. • Glitch detection on all channels. • Marker measurements. • Timing and Scope Autoscale. • Scope Automeasure. • Pattern, edge, and glitch triggering. • Overlapping of waveforms. • Small lightweight probing. • Time and number of states tagging. • State Compare, Waveform, and Chart.
