A logic analyzer captures many digital signals simultaneously and displays their timing and state relationships, letting an engineer see what a digital circuit is actually doing across an entire bus rather than one signal at a time. It is the instrument that makes complex digital interactions — handshakes, bus transactions, state machine sequences — observable in a way that an oscilloscope alone cannot match. The Agilent 16750A, 16751A, and 16752A are plug-in logic analyzer modules in this category, designed for designers of next generation computer, networking, and communications systems.

According to the datasheet, these modules are intended for debugging the latest microprocessors and high-speed data buses, where fast state speed is critical for capturing data accurately while the device under test runs at full speed. The datasheet also identifies deep memory analysis of difficult-to-reproduce problems as a primary use case, noting that memory depth is an invaluable resource when an engineer needs to capture all the clues required to solve an intermittent issue. The modules are positioned for next generation computer, networking, and communications system designs.

Brand Heritage

Agilent Technologies was the test and measurement business spun out of Hewlett-Packard in 1999, and these logic analyzer modules date from that early Agilent period. In 2014 the electronic measurement business was transferred from Agilent to Keysight Technologies, which continues the lineage today. Instruments branded HP, Agilent, and Keysight from this product family share the same engineering heritage.

Compare Other Models in This Series

The 16750A, 16751A, and 16752A form a three-model logic analyzer module family from Agilent Technologies, sharing a common feature set across state speed, timing speed, channel count, and Timing Zoom. The datasheet introduces all three as logic analyzer modules for designers of next generation computer, networking, and communications systems.

Within the family, the models share 400 MHz maximum state speed, 800 MHz half-channel or 400 MHz full-channel conventional timing speed, 2 GHz Timing Zoom, and 68 channels per module. They differ only in acquisition memory depth, allowing a buyer to scale memory to the capture-duration requirement of their application without changing the underlying acquisition platform.

Each pre-owned model below is its own dedicated product page with condition-matched pricing and current availability. Use the comparison table to identify the memory depth that fits the application, then visit the linked model page for full specifications and ordering details.

The single specification that varies across the family is acquisition memory depth. The 16750A provides 4 M samples per channel, the 16751A provides 16 M samples per channel, and the 16752A provides 32 M samples per channel. All other headline specifications — state speed, timing speed, Timing Zoom, and channel count — are identical across the three modules.

The right choice depends on capture duration requirements at the chosen sample rate. Longer captures of difficult-to-reproduce events or extended bus transactions favor the deeper-memory 16751A or 16752A, while shorter captures of well-defined trigger sequences can be served by the 16750A. The comparison table below presents the specification differences side by side.

Additional differences in specifications beyond the few shown above are not listed here — see each model's full specifications below.
