Tektronix TDS7000 and TDS7000B Series Oscilloscopes
6 models with full specifications from Tektronix.
The Tektronix TDS7000 and TDS7000B series are high-performance digital phosphor oscilloscopes (DPOs) engineered for digital design, signal integrity analysis, and compliance testing. Operating on open Windows platforms with OpenChoice software, these four-channel instruments combine high-bandwidth analog acquisition with fast waveform capture rates. The family covers bandwidths ranging from 500 MHz up to 7 GHz, with real-time sample rates reaching up to 20 GS/s. By utilizing either DPX or FastAcq acquisition technologies, these oscilloscopes capture more than 400,000 waveforms per second, enabling engineers to identify transient faults and signal anomalies. This guide details the technical variations across the series, comparing bandwidth, probe interfaces, and acquisition specifications to help technical buyers select the correct model.

Bandwidth and Rise Time Performance
The primary differentiator within the TDS7000 and TDS7000B series is the analog bandwidth and corresponding rise time performance. The series entry models include the Tektronix TDS7054 with a 500 MHz bandwidth and the Tektronix TDS7104 with a 1 GHz bandwidth. For mid-range measurement demands, the Tektronix TDS7154 provides a 1.5 GHz bandwidth and a calculated rise time of 240 ps. High-speed digital design and compliance testing require the high-bandwidth models: the 4 GHz Tektronix TDS7404 and Tektronix TDS7404B (both featuring a typical rise time of 100 ps) and the flagship 7 GHz Tektronix TDS7704B, which delivers a calculated rise time of 62 ps (10% to 90%) or 43 ps (20% to 80%).
Sample Rates and Channel Allocation
Real-time sample rates scale across the family to match the bandwidth capabilities. The entry-level Tektronix TDS7054 features a maximum sample rate of 5 GS/s. The Tektronix TDS7104 increases this to 10 GS/s when using 1 or 2 channels, dropping to 5 GS/s across 3 or 4 channels. The high-bandwidth models, including the Tektronix TDS7154, Tektronix TDS7404, Tektronix TDS7404B, and Tektronix TDS7704B, offer a maximum real-time sample rate of 20 GS/s. This maximum rate is channel-dependent; for instance, the Tektronix TDS7404 delivers 20 GS/s on 1 channel, 10 GS/s on 2 channels, and 5 GS/s when utilizing 3 or 4 channels.
Probing and Connectivity Interfaces
Physical interfaces vary between the different models. The Tektronix TDS7054 and Tektronix TDS7104 utilize the TekProbe BNC probe interface, which supports traditional active and passive probes. In contrast, the Tektronix TDS7154, Tektronix TDS7404B, and Tektronix TDS7704B feature the high-bandwidth TekConnect interface, designed to maintain signal integrity at gigahertz frequencies. Standard system connectivity is robust across the entire family, with models offering GPIB, LAN (10/100Base-T), RS-232, Centronics Parallel, and VGA ports. The B-generation models (such as the Tektronix TDS7404B and Tektronix TDS7704B) feature standard USB interfaces for peripheral support.
Frequently asked questions
- What display resolutions do these oscilloscopes feature?
- Display resolution varies by model. For instance, the Tektronix TDS7154 features a 10.4-inch display with a resolution of 640 x 480 pixels, whereas the Tektronix TDS7404B and Tektronix TDS7704B feature a 10.4-inch XGA display with a resolution of 1024 x 768 pixels.
- How does input coupling differ across the series?
- The lower-bandwidth Tektronix TDS7054 and Tektronix TDS7104 support AC, DC, and GND input coupling. The high-performance Tektronix TDS7154, Tektronix TDS7404, Tektronix TDS7404B, and Tektronix TDS7704B are designed for high-frequency signal integrity and limit input coupling to DC and GND with a fixed 50 Ohm input impedance.
