The Tektronix DTGM32 is a 2-channel output module for the DTG5000 series Data Timing Generators, engineered to deliver precise signal generation for HDMI pre-compliance and compliance testing. It provides a cost-effective jitter generation solution that eliminates the need for complex Arbitrary Waveform Generators in advanced testing scenarios.
Technical Specifications
• Channels: 2 independent analog output channels
• Data Rate: Up to 350 Mb/s (based on rise time)
• Jitter Generation Frequency: Up to 50 MHz with 1 MHz resolution
• Jitter Amplitude: Up to 1 ns or 2 ns (configuration and data rate dependent); up to 16.5 UIpk-pk (data rate and frequency dependent)
• Output Levels: 1.25 Vpk-pk into 50 Ω; 2.5 Vpk-pk into 1 MΩ
• Output Impedance: 50 Ω and 1 MΩ
• External Jitter Control Inputs: 2 SMA connectors for external modulation
• Cross-point Adjustment: 30% to 70% with 1% resolution (NRZ mode)
• Maximum Output Current: ±40 mA or ±80 mA (mainframe dependent)
– Key Features
• Supports multiple jitter profiles: Sine, Gaussian Noise, Square, and Triangle waveforms
• Precise timing control for complex waveform generation
• Duty cycle distortion adjustment from 30% to 70%
• Two independent external jitter modulation inputs for flexible signal conditioning
– Typical Applications
• HDMI pre-compliance testing
• HDMI compliance testing
• High-speed digital signal generation requiring precision jitter control
• Data timing applications requiring configurable waveform parameters
– Compatibility & Integration
The DTGM32 operates as a plug-in module for Tektronix DTG5000 series mainframes, including DTG5078, DTG5274, and DTG5334. Installation in DTG5078 or DTG5274 may require OS upgrade to firmware version 1.xx.
