Portable Logic Analyzers
The HP/Agilent/Keysight 1660-series (1660A, 1660AS, 1661CS, 1662CS, 1663AS) and similar self-contained units pack a fixed channel count and their own display into a standalone instrument, built to be used on the bench without a separate mainframe or host computer. This is the more approachable entry point into logic analysis — everything needed is in one box.
Modular Mainframe Systems
The 16500 and 16700-series mainframes accept plug-in acquisition modules — cards like the 16554A, 16716A, and 16517 — letting you configure total channel count and mix capabilities (logic analysis alongside pattern generation, for instance) by choosing which modules to install. This modularity is what made these systems the standard for serious digital debugging work through the 1990s and 2000s, and used mainframe/module combinations remain a genuinely cost-effective way to get high channel counts today.
VME Logic Analyzer Modules
The Curtiss-Wright/VMETRO cards in this category are board-level logic analyzer hardware that installs directly into a VME chassis as part of an embedded system, rather than a standalone bench instrument — common in military, aerospace, and industrial systems where the acquisition hardware needs to live inside the same chassis as the equipment under test. As with any VME-format product, confirm you have a compatible chassis before ordering.
What to Check Before Buying
Confirm the probe/pod set for your target bus is included — probing accessories are model-specific and generally not interchangeable between different logic analyzer families. For older GPIB-controlled mainframes, ask about control software and OS compatibility, since some of this hardware was built around software expecting a legacy Windows environment.
Calibration for Logic Analyzers
Logic analyzers are typically functionally verified — timing accuracy and threshold-level accuracy checked against a reference — rather than issued a calibration certificate the way an analog measurement instrument would be, since the core measurement is a digital threshold comparison rather than an analog reading.

Frequently Asked Questions
What does a logic analyzer do that an oscilloscope can't? +
An oscilloscope shows a small number of channels (typically 2-4, sometimes more) with full analog waveform detail — exact voltage levels, rise times, noise. A logic analyzer captures far more channels at once (often 32, 68, or over 100) but only as digital 1s and 0s against a common time base, letting you see the relationship between many signals across a parallel bus or digital interface simultaneously. If you need to see whether address, data, and control lines on a bus are toggling in the right sequence relative to each other, that's a logic analyzer job, not an oscilloscope job.
What is the difference between the HP/Agilent 1660-series and the modular mainframes like the 16700-series? +
The 1660-series (1660A, 1660AS, 1661CS, 1662CS, 1663AS, etc.) are self-contained portable logic analyzers with a fixed channel count and their own display, built to be used as a standalone instrument. The modular mainframes (16700-series and the 16500-series before it) are chassis that accept plug-in acquisition modules — 16554A, 16716A, 16517, and similar cards — letting you configure channel count and capability by choosing which modules to install, and mix logic-analyzer modules with other module types like pattern generators in the same mainframe.
What is the Curtiss-Wright/VMETRO hardware in this category? +
These are VME-bus logic analyzer modules — board-level acquisition hardware that installs directly into a VME chassis as part of an embedded system, rather than a standalone bench instrument. They're used in military, aerospace, and industrial systems where the logic-analysis capability needs to live inside the same chassis as the hardware under test. A VME logic analyzer card is only useful if you already have a compatible VME chassis to install it in.
Will an older logic analyzer still work with modern equipment? +
The acquisition hardware itself doesn't age in a way that affects its ability to capture signals, but check two practical things: whether the probe/pod set for your specific target bus is included (probing accessories are model-specific and not always interchangeable), and whether the control software runs on an OS you can still use, particularly for older GPIB-controlled mainframes that may expect a legacy Windows environment.
