The Keysight/Agilent/HP 16950A is a 68-channel logic analyzer module engineered for high-speed digital system debugging and verification. It delivers timing analysis up to 4 GHz with 250 ps resolution, state analysis to 600 MHz, and selectable memory depths from 256 K to 64 M. The module integrates into Keysight 16900 Series mainframes and scales to 340 channels across five modules, supporting both single-ended and differential signals with threshold adjustment from -3 V to 5 V in 10 mV increments.
## Technical Specifications
**Channel Architecture**
• 68 channels per module
• Maximum 340 channels (5 modules combined)
• Single-ended and differential signal support
**Timing Analysis (Asynchronous Sampling)**
• 4 GHz timing zoom at 250 ps resolution with 64 K memory
• 1.2 GHz half-channel or 600 MHz full-channel conventional timing with deep memory
• 600 MHz transitional timing
**State Analysis (Synchronous Sampling)**
• State clock rates to 600 MHz

• Simultaneous eye diagrams across all channels
**Memory Configuration**
• Selectable depths: 256 K, 1 M, 4 M, 16 M, 32 M, 64 M
• Memory depth upgrades available
**Signal Conditioning**
• Threshold adjustment: -3 V to 5 V in 10 mV increments
• Automated threshold and sample position setup for high-speed bus measurements
## Key Features
• Versatile triggering for complex digital designs
• Deep memory options enable extended capture windows
• Eye diagram analysis identifies signal integrity problems in real time
• 90-pin probe interface (probes ordered separately)
## Compatibility & Integration
The 16950A interfaces with Keysight 16900 Series mainframes and maintains backward compatibility with discontinued 16700 Series and 16500C platforms. Multiple modules combine within a single mainframe, defaulting to the lowest memory depth in the set. The module works alongside other 16700 Series logic analyzer cards (16753A, 16754A, 16755A, 16756A) in multi-card configurations.
