Tektronix DPO3000 Series Digital Phosphor Oscilloscopes
6 models with full specifications from Tektronix.
The Tektronix DPO3000 Series is a family of benchtop digital phosphor oscilloscopes (DPOs) engineered for the analysis, visualization, and debugging of complex electronic designs. Ideal for technical buyers and practicing engineers, these instruments offer a balance of sampling performance and deep memory across all configurations. The series spans analog bandwidths from 100 MHz up to 500 MHz, with options for either 2 or 4 analog channels. Each model in this family shares a unified platform footprint, including a large 9-inch widescreen display, standard 5 Mpoint record length, and a 2.5 GS/s real-time sample rate on all channels, providing high-fidelity signal capture and deep analysis capabilities.

Shared Platform Performance
All models in the DPO3000 Series are built on a shared platform architecture. This includes a standard 5 Mpoint record length on all channels and a real-time sample rate of 2.5 GS/s across all inputs. With a waveform capture rate of 50,000 wfm/s, these instruments are designed to reveal transient anomalies and signal jitter that standard digital storage oscilloscopes might miss.
For visualization, every model features a 9.0-inch (228.6 mm or 229 mm) WVGA widescreen color TFT-LCD with an 800 x 480 resolution. Connectivity is uniform across the series, offering USB 2.0 Host ports (on both front and rear panels), a USB 2.0 Device port for computer connectivity, a 10/100 Base-T Ethernet LAN port, and a DB-15 video out (SVGA) port for external displays.
Comparing Models by Bandwidth and Channels
The primary selection criteria within the DPO3000 Series are analog bandwidth and input channel count. The family is divided into three performance tiers:
- 100 MHz Models: The 2-channel DPO3012 and the 4-channel DPO3014 feature a calculated rise time of 3.5 ns. They are well-suited for general-purpose, lower-speed debugging and include a 20 MHz hardware bandwidth limit.
- 300 MHz Models: The 2-channel DPO3032 and the 4-channel DPO3034 offer a calculated rise time of 1.17 ns, providing the necessary performance for debugging moderately high-speed serial buses and microcontroller interfaces.
- 500 MHz Models: The 2-channel DPO3052 and the 4-channel DPO3054 provide the highest performance in the family, featuring a rapid calculated rise time of 700 ps to accommodate fast-edge signal analysis. The 500 MHz models support hardware bandwidth limits at both 20 MHz and 250 MHz.
Vertical System and Signal Integrity
The vertical system across the series features an 8-bit analog-to-digital converter (ADC). On specific models like the DPO3012 and DPO3032, this can be extended up to 11 bits using High Resolution (HiRes) mode.
Every model offers dual input impedance modes to match different testing environments: a 1 MΩ path (parallel with 13 pF on most models, and 11.5 pF on the DPO3012) and a 50 Ω path. The vertical sensitivity ranges from 1 mV/div to 10 V/div at 1 MΩ, and 1 mV/div to 1 V/div at 50 Ω. DC Gain Accuracy is rated at \u00b11.5% for settings of 5 mV/div and above, \u00b12.0% at 2 mV/div, and \u00b12.5% at 1 mV/div.
Form Factor and Environmental Tolerances
DPO3000 Series models share a highly consistent benchtop footprint. The 4-channel configurations (DPO3014, DPO3034, DPO3054) and the 300 MHz/500 MHz 2-channel configurations (DPO3032, DPO3052) share physical dimensions of 416.6 mm (or 417 mm) x 203.2 mm x 137.2 mm and weigh approximately 4.2 kg (4.17 kg for the DPO3032). The 100 MHz, 2-channel DPO3012 is slightly narrower, measuring 375 mm x 203.2 mm x 137.2 mm.
All instruments are rated for operation within a temperature range of 0 \u00b0C to +50 \u00b0C and require a minimum cooling clearance of 50 mm (2 inches) on the left side and rear.
Frequently asked questions
- What is the standard record length of the DPO3000 Series models?
- All models in the DPO3000 Series feature a standard record length of 5 Mpoints on all channels.
- Do these oscilloscopes support hardware bandwidth limiting?
- Yes. The 100 MHz and 300 MHz models (such as the DPO3012, DPO3014, and DPO3032) support a 20 MHz hardware bandwidth limit. The 500 MHz DPO3052 supports both 20 MHz and 250 MHz hardware bandwidth limits.
- What is the maximum input voltage for the 50 ohm and 1 megohm inputs?
- For the 1 M\u03a9 input impedance path, the maximum input voltage is 300 V RMS CAT II (with peak limits specified up to \u00b1450 V on models like the DPO3012, DPO3032, and DPO3052). For the 50 \u03a9 input path, the maximum input voltage is 5 V RMS with peaks less than or equal to \u00b120 V.
