Tektronix DG2000 Series Digital Pattern Generators
4 models with full specifications from Tektronix.
The Tektronix DG2000 Series digital pattern generators are high-performance instruments designed for evaluating digital semiconductors, logic circuits, and high-speed transmission systems. These units share a core architecture that includes standard GPIB (IEEE-488.2) and RS-232-C remote control interfaces, but they differ significantly in their maximum data rates, channel capacities, and analog output characteristics. Engineers can choose between modular, high-channel-count options running at lower speeds or specialized dual-channel configurations running at gigabit-per-second rates. This series is ideal for characterization, debug, and validation processes where precise control over digital pattern parameters is required.

Channel Count and Performance Trade-offs
Selecting a model within the DG2000 series requires balancing speed requirements against the necessary channel count:
- High Channel Density: The Tektronix DG2020 and Tektronix DG2020A support up to 36 channels (configured as 12 channels per pod, for up to three pods). These models provide a maximum data rate of 200 Mb/s, making them suitable for parallel logic analysis and multi-channel system debugging.
- Mid-Range Speed & Expandability: The Tektronix DG2030 operates at data rates up to 409.6 Mb/s. It features 4 standard channels, expandable to 8 channels with Option 01, and offers a deep pattern memory of 256 Kwords per channel.
- High-Speed Serial Testing: For applications requiring gigabit rates, the Tektronix DG2040 provides 2 channels capable of data rates from 100 b/s up to 1.1 Gb/s. It features sub-nanosecond edge control with transition times of 150 ps or less at 1 Vp-p.
Output Configurations and Electrical Specifications
The series utilizes distinct output designs and connection interfaces tailored to specific speed and voltage requirements:
- Modular Output Pods: The Tektronix DG2020 relies on external pods to define logic level compatibility. Supported pods include the P3410 for TTL, the P3420 for ECL, and the P3447 for variable voltages. The P3447 pod provides a high-level output range of -2.0 V to +7.0 V and a low-level range of -3.0 V to +6.0 V.
- Programmable Output Levels: The Tektronix DG2030 features SMB connectors and allows precise output level adjustments. The high-level voltage ranges from -1.25 V to +3.50 V, while the low-level voltage ranges from -1.50 V to +3.25 V, resulting in an amplitude range of 0.10 Vp-p to 4.75 Vp-p.
- High-Speed SMA Outputs: Designed for high-speed logic, the Tektronix DG2040 uses SMA front-panel connectors. It provides complementary outputs (CH1/CH1_bar, CH2/CH2_bar, CLK/CLK_bar) with an amplitude of 0.1 Vp-p to 2.0 Vp-p and a voltage offset range of -1.625 V to +1.625 V.
Integration and Software Support
The physical chassis designs across the series are similarly sized, weighing approximately 10.5 kg and operating on AC power supplies from 90 V to 250 V. Remote integration is supported via GPIB and RS-232 serial interfaces on all models. For system setup, the Tektronix DG2020A supports remote pattern data importation through the DG-Link Software Utility.
Frequently asked questions
- Which output pods are compatible with the DG2020 model?
- The Tektronix DG2020 supports three specific output pod options: the P3410 (TTL), the P3420 (ECL), and the P3447 (Variable Voltage).
- Can the channel capacity of the DG2030 be expanded?
- Yes. While the Tektronix DG2030 comes standard with 4 data output channels, it can be expanded to 8 channels by using Option 01.
- Does the DG2040 support differential or complementary signals?
- Yes. The Tektronix DG2040 features standard complementary outputs on the front panel for Channel 1, Channel 2, and the clock (CH1/CH1_bar, CH2/CH2_bar, and CLK/CLK_bar).
