HP 1631A/D provides a digitizing oscilloscope and a logic analyzer in one low-cost instrument. It offers analog, timing, state, and system performance analysis capabilities function separately or interactively to serve the needs of digital design and test engineers.
The A and D models differ only in state/timing channel width. The HP 1631A provides up to 35 state channels, eight timing channels, and two analog channels. The HP 1631D provides up to 43 state channels, 16 timing channels, and two analog channels.The One Tool For Every Phase Of Digital Design And Test
Analog waveform analysis provides simultaneous display of up to two channels User-definable labels, wide magnification range, and direct readout of time and voltage between cursors are available.
State listings and waveforms provide displays and windowing of address, data, status, and control line activity. Selectable display modes include binary, octal, decimal, hexadecimal, ASCII, relocation, user-defined mnemonics, and microprocessor-specific mnemonics. You can assign labels, and display and/or trigger on code in terms of relocatable or absolute addresses, or mnemonics.
Timing waveform diagrams provide simultaneous display of up to 16 channels, with user-definable labels. Wide magnification range, glitch display, and direct readout of time between cursors are available.
Time interval and event histograms let you view system hardware/software activity or specific modules for performance evaluation. Out-of-spec conditions or bottlenecks in program flow or hardware execution stand out. In addition, the display shows measurement data, including the minimum, maximum, average value, and total measurement time.
Full state analyzer indexing can arm analog waveform acquisition. Full analog triggering can arm state data acquisition.
Full state analyzer indexing can arm timing waveform acquisition. Full timing analyzer indexing can arm state data acquisitions.
Automatic time-interval measurements are provided through analog X and O cursors, with statistical calculations to enhance accuracy. A search-and-then-stop mode stops waveform acquisition when user-definable trigger conditions are met.

Displaying program activity in inverse assembly can save many hours in test and debug. No more time-consuming or error-prone conversions from hex because measurement listings appear just as you wrote them, making them easy to compare to source-code listings.
HP provides a complete line of microprocessor preprocessors that tailor the HP 1631A/D to specific microprocessors. Preprocessor interface modules contain circuitry that properly formats data, and they provide connection via a microprocessor socket. Software supplied with preprocessors performs inverse assembly for state displays in the selected microprocessor's mnemonics.
A bus preprocessor available for analyzing RS-232C/V.24, RS-449, and HP-IB data bus, and minicomputer interface modules are also available for use with HP logic analyzers.
