High-Fidelity Signal Acquisition

The high bandwidth (500 MHz) of the TDS714L together with its sample rate (500 MS/s) shows the true signals that other scopes may be missing. The TDS714L provides a wide dynamic range, flat response, fast overdrive recovery, calibrated DC offset, 1-mV/div sensitivity, 1-ns peak detect, and internal calibration.

Easy to Learn and Easy to Use

Extensive user interface design has made the TDS714L truly intuitive to operate. It offers a familiar front-panel layout with dedicated vertical, horizontal, and trigger controls. A graphical user interface with over 200 icons helps facilitate understanding and use of the advanced features. A color monitor helps rapidly distinguish between multiple waveforms and measurements. Online help provides a convenient built-in reference manual.

Powerful and Flexible Triggering

In addition to basic triggering such as edge and pulse-width, the TDS714L has several trigger modes tailored for specific design and debug applications. Logic and pulse triggers, including setup/hold, glitch, slew rate, and time-out triggers, capture hard-to-catch digital design problems. The optional video trigger provides line and field selection for NTSC, PAL, and HDTV standards.

Advanced Performance Features

Color Grading - Displays historical information that has been acquired over time.

Automatic Measurements - Eliminate the need for manually measuring the waveform against the graticule or with cursors. Measurement gating allows the user to select a specific part of the live waveform for measurement. Measurement statistics (min, max, mean, and standard deviation) give additional information about the variations in the measurements over time (for example, worst-case excursions), increasing the confidence in the quality of the measurements.

Waveform Histograms - Allow the examination of the statistical nature of the signal. Horizontal histograms, which are useful for evaluating signal jitter, sample the waveform within a specified region, sort the values into time bins, and plot the accumulated bin values versus time. Vertical histograms, which are useful for evaluating signal noise, sample the waveform within a specified region, sort the values into amplitude bins, and plot the accumulated bin values versus amplitude.

Applications Software Packages

These Java based applications packages reduce the cost, time, and complexity common to many application-specific test procedures. Application-specific capabilities require a hard disk drive (Opt. HD or Opt. 2M).

TDSDDM1 (Disk Drive Measurement Application) provides users with industry standard measurements such as Track Average Amplitude (TAA), 50% Pulse Width (PW50), Non-Linear Transition Shift (NLTS), and Signal-to-Noise Ratio (SNR). This capability gives disk drive designers direct measurements in industry standard terminology.

TDSPWR1 (Power Measurement Application) gives designers interested in power consumption applications the ability to automatically calculate True Power, Apparent Power, Power Factor, Instantaneous Power, and Energy to eliminate manual calculations. In addition, this package provides precompliance current harmonics testing to the EN 61000-3-2 standard.

TDSJIT1 (Jitter and Timing Analysis Application) performs a suite of jitter measurements with unprecedented accuracy on single-shot waveforms. Jitter information can be displayed as statistics, histograms, or profiles.

TDSPSM1 (Processor Specifications Measurement Application) introduces a revolutionary way for making timing measurements by providing statistics on specific data and clock edges that are fully time-correlated. This application also performs automated AC timing measurements on all parameters in single-shot acquisitions.

Complementary Measurement Accessories

Tektronix provides a wide range of measurement accessories optimized for the TDS family. These accessories are designed to operate by using the TEKPROBE™ interface, which provides power and automatic scaling, to complete measurement solutions.

Active Probes were designed to be compatible with the TDS714L. For example, the P6243 is capable of achieving the full 500-MHz bandwidth on a TDS714L while providing low loading.

High-Bandwidth Differential Probes (P6247) enable high-bandwidth differential measurements while maintaining high common-mode rejection.

Current Probes such as the TCP202 and High-Voltage Differential Probes such as the P5205 and P5210 allow safe, high-power measurements. Direct Probe Readouts use information from the probes to display measurements in units of Amps, Volts, and Watts.

Sophisticated Documentation

Save screen displays in a number of standard desktop publishing formats to the internal 3.5-in. MS DOS-compatible floppy disk drive, optional internal hard disk, or external Zip or Zip Plus drive. Import the screen file into word processing applications. Make hard copies directly to monochrome or color printers and plotters connected to the computer network (LAN), GPIB, RS-232, or Centronics ports, or acquire waveforms, screen displays, and scope settings using Tektronix WaveStar™ software running on a PC interfaced to the GPIB port.
