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.
## Technical Specifications
• Logic Level: 5 V TTL
• Maximum Clock Speed: 200 MHz
• Output Driver: 10H125 with 100 ohm series impedance
• Channels: 8 output channels per pod
• Skew (Typical): Less than 4 ns
• Skew (Worst Case): 4 ns
• Dimensions: 6 × 4 × 1 inches
• Weight: Approximately 0.6 lbs
## Key Features
• Fixed output impedance configuration minimizes reflections and signal degradation
• Low temporal skew across all eight channels enables synchronous multi-channel stimulus generation
• Compact form factor allows multiple pods to be ganged for extended channel counts
## Typical Applications
• Digital circuit stimulus and verification during logic analysis
• Pattern generation for TTL-compatible devices
• Multi-channel timing validation in embedded systems
• 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.
