With a 9-inch WVGA display, 20 million point record length and 1 GS/s sample rate, TBS2074 Oscilloscope captures and display significantly more signal to help you evaluate designs faster. Easily and confidently analyze your signals with new on-waveform cursor readouts and 32 automated measurements, each with informative tips to help you quickly choose the right one. The TekVPI® probe interface works with traditional BNC connections, but also enables wide application coverage with the latest active voltage probes and current probes.

Designed to make your work easier

The TBS2074 is designed for easy operation and quick hands-on learning. Dedicated controls provide quick access to important settings, so you can evaluate signals faster. Many oscilloscopes provide 8 vertical divisions and 10 horizontal divisions, but the TBS2074 gives you 10 vertical divisions and 15 horizontal divisions, so you can see more of your signal. The display also offers more room for measurement results and menu information.

Designed for outstanding waveform visualization and analysis

Long record length with pan and zoom 

Record length is selectable, from 2000 samples up to 20 million samples for capturing long time periods. The exceptionally long record length will help you find signal anomalies and verify digital communications. To help navigate long acquisitions, the Zoom function lets you quickly pan through the record and zoom in to see signal details.

Versatile triggering and acquisition modes 

The trigger system is designed for troubleshooting today's mixed signal designs. Beyond a basic edge trigger, it also includes pulse width and runt triggering, which are especially useful for troubleshooting digital sections of your designs. Pulse width triggering is perfect for hunting narrow glitches or timeout conditions. You specify a voltage threshold and a width, and the oscilloscope triggers when the pulses are too narrow, too wide, or of a particular duration. Runt triggering is designed to capture signals that are shorter in amplitude than expected. It lets you specify two voltage thresholds and a width. If a pulse amplitude falls between the two thresholds, the oscilloscope will trigger.

The default acquisition mode is Sample Mode which works well for most applications. However, the instrument also offers Peak Detect Mode which is useful for hunting spikes and Average Mode which can help reduce noise on repetitive signals.

Automated measurements are easier than ever

A comprehensive set of automated measurements enable fast and convenient testing for a wide range of signals and applications. A single measurement selection screen makes it easy to choose from 32 automated measurements without having to hunt through multiple menus. Choose from among your most frequently-used measurements which are tracked at the top of the page, or select from four categories: frequency, time, amplitude, and area.

Measurements are color-coded by the source and are presented on a transparent background, so waveforms are not obscured by the readouts.

FFT function 

You can understand the frequency content of your signals with the FFT function by pressing the dedicated front-panel FFT button. Display only the FFT, or turn on the source waveform display to see both the spectrum and the time domain waveform. A transparent readout shows important settings without blocking the FFT display.

Built-in tips for faster setup

HelpEverywhere is a unique feature on theTBS2000. It shows instant help information as you navigate through key menus. The tips include measurement information, application tips, and general guidance in the form of text and graphics. You can turn tips on and off from the HelpEverywhere menu.

On-screen scope fundamentals

Scope Intro is a brief handbook embedded in the TBS2000. Pressing the front panel Function button gives you access to information on oscilloscope basic operations, as well as an overview of the TBS2000 and TekSmartLab Lab Management System for education.

First in its class with wireless communications

On the rear of the instrument, you will find several communications ports. The USB device port or LAN port can be used to control the instrument using the fully-documented command set. 

The TBS2000 is the first oscilloscope in its class to support wireless communication. Plug a Wi-Fi dongle into the USB host port and set the interface for Wi-Fi from the front panel. A Wi-Fi dongle is available as TEKUSB-WIFI. Several off-the-shelf dongles have also been tested and their operation confirmed.

LXI embedded Web page for instrument control

LXI is an industry standard based on LAN connectivity for flexible, reliable, and efficient communication and control. TBS2000 supports LXI Core 2011. The TBS2000 LXI Web page can be accessed by simply typing the instrument IP address into any Web browser.

TekVPI® Interface and active probe support 

The TekVPI probe interface sets the standard for ease of use in probing. With this interface the TBS2000 Series supports a wide range of the latest voltage and current probes, providing coverage for many applications. These probes are powered by and communicate with the TBS2000 through the interface. Scale factors and status information, such as error conditions, are sent to the instrument for processing and display. This saves you from having to manually set scale factors, calculate offsets, or monitor for open jaw conditions or the need to degauss your current probes.

Innovative new education solutions

The TBS2000 offers distinctive new ways to enable educators to devote more time to teaching circuit concepts instead of lab setup and management. The integrated Courseware function allows professors to load lab exercises on the instrument to give students guidance at each station and provides a structured framework into which students can capture data to incorporate into their reports. Over 100 sample lab exercises are available for download.

Performance you can count on

Tektronix has industry-leading service and support, and every TBS2000 series oscilloscope is backed with a standard 5-year warranty.
