The Tektronix TDS6000 Series — comprising the TDS6604 and TDS6404 — is a family of digital storage oscilloscopes built for verification, debug, and characterization of sophisticated electronic designs. Each instrument pairs high-performance signal acquisition with classic analog-style controls, a large touch-sensitive display, and graphical menus, while open access to the Windows operating system enables customization and extensibility.
A digital storage oscilloscope captures fast electrical signals and displays them as voltage-versus-time waveforms, letting an engineer examine amplitude, timing, and signal shape. The TDS6000 Series is applied to the validation and characterization of high-speed digital designs, jitter and timing analysis, and the investigation of transient phenomena. Compliance mask tests support a wide range of computer and datacom standards, and a 32-bit serial trigger isolates pattern-dependent effects.
ValueTronics stocks and holds its own inventory in a 20,000 square-foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. Every used unit we sell is inspected and functionally verified in-house before it ships, while new units ship factory-sealed exactly as received from the manufacturer. Operating since 1992, we match the right instrument and condition to each customer's application.
The Tektronix TDS6000 Series brings high-performance signal acquisition, operational ease, and open connectivity to the verification, debug, and characterization of sophisticated electronic designs. The family is built around exceptional acquisition and trigger performance, a touch-sensitive interface, and an open Windows environment shared across its models.
Within the series, the TDS6604 and TDS6404 share the same four-channel architecture, 20 GS/s sample rate on one or two channels, display, and connectivity, differing principally in analog bandwidth and rise time.
Each model in the series is offered below as its own dedicated pre-owned product page with condition-matched pricing. Select the bandwidth tier that fits your application, then choose the pre-owned listing for that specific model.
The two models are distinguished by their bandwidth tiers: the TDS6604 provides 6 GHz analog bandwidth with a typical rise time of 70 ps, while the TDS6404 provides 4 GHz bandwidth with a 100 ps typical rise time. Channel isolation is specified to ≥20:1 at each model's full bandwidth — 6 GHz for the TDS6604 and 4 GHz for the TDS6404. The comparison table below summarizes these per-model figures.
Beyond bandwidth and rise time, the models share their core capabilities — four input channels, 20 GS/s real-time sampling on one or two channels, 10 GS/s on four channels, identical acquisition modes, and the same Windows-based analysis and networking platform. Each also ships with a different probe calibration and deskew fixture matched to the model (067-0484-xx for the TDS6604, 067-0405-xx for the TDS6404).

|---|---|---|---|
| TDS6404 | 4 GHz | 100 ps | 20 GS/s |
| TDS6604 | 6 GHz | 70 ps | 20 GS/s |
