Keysight / Agilent / HP 10461A TTL Data Pod

The Keysight 10461A TTL Data Pod is a digital signal interface accessory for logic analyzers, enabling acquisition and analysis of TTL-level signals from digital circuits. This eight-channel output pod operates at 5 V TTL logic levels with a maximum clock speed of 200 MHz and is optimized for use with Keysight 1670G Series pattern generators (Option 004). Each pod delivers eight independent output channels with 10H125 drivers featuring 100 ohm series impedance and tight temporal characteristics - typical skew under 4 ns and worst-case skew of 4 ns - making it suitable for precision timing-critical applications.

Protocol emulation and functional testing of digital interfaces

Compatibility & Integration The 10461A interfaces with Keysight logic analyzers and integrates with the 1670G Series pattern generator via Option 004. The Keysight 10474A Lead Set is the recommended interconnection solution. Both the pod and lead set are obsolete per Keysight's End-of-Life designation due to non-compliance with EU RoHS Directive 2011/65/EU, though third-party suppliers may offer used or refurbished units.
