The Tektronix DTGM20 is a plug-in output module for the DTG5000 Series Data Timing Generator mainframe. It combines data and pulse generation capabilities into a single 4-channel output card, delivering up to 3.35 Gb/s data rates. The module features four SMA connectors for single-ended signal output with selectable source impedance and configurable rise/fall times, making it suitable for high-speed digital testing, protocol validation, and timing characterization across multiple test configurations.
Technical Specifications
• Data Rate: Up to 3.35 Gb/s (with DTG5334 mainframe)
• Output Channels: 4 or 2×1 (channels 3–4 unavailable in DTG5274/DTG5334)
• Connectors: 4 SMA single-ended outputs
• Amplitude (50 Ω load): 3.5 Vp-p, 5.35 Vp-p, or 3.90 Vp-p depending on configuration
• Amplitude (1 MΩ load): 7 Vp-p, 7.81 Vp-p, or 2.5 Vp-p depending on configuration

• Rise/Fall Time (20–80%, 1 Vp-p into 50 Ω): < 540 ps, < 340 ps, or < 110 ps depending on configuration
– Key Features
• Modular plug-in design compatible with DTG5078, DTG5274, and DTG5334 mainframes
• Slot-flexible installation in any available module position (slots A–H)
• Installable in any combination with other DTG5000 series output modules
• No inhibit input or external jitter input support
– Typical Applications
• High-speed serial data generation and testing
• Pulse timing characterization
• Multi-channel signal sourcing for protocol validation
• Digital circuit timing analysis
– Compatibility & Integration
The DTGM20 installs in any slot within compatible DTG5000 mainframes and operates alongside DTGM10, DTGM21, DTGM30, DTGM31, and DTGM32 modules. Power off the mainframe before module installation or removal. Handle SMA connectors by the nut only to prevent damage.
