Acquisition Features Separate Digitizers. Ensure accurate timing measurements with separate digitizers for each channel. Acquisition on multiple channels is always concurrent. The digitizers can also be combined to yield a higher sample rate on a single channel. Fast Acquisition. Acquire up to 400,000 waveforms per second to see rapidly changing signals or intermittent signal irregularities. Long Record Lengths. Choose record lengths from 500 points up to 500,000 points per channel (up 2,000,000 points on a single channel). Extend the maximum record length up to a maximum of 64,000,000 points with memory options. Peak Detect Acquisition Mode. See pulses as narrow as 400 ps even at the slower time base settings. Peak detect helps you see noise and glitches in your signal. Acquisition Control. Acquire continuously or set up to capture single shot acquisitions. Enable or disable optional acquisition features such as equivalent time or roll mode. Use Fast Frame acquisition to capture and time stamp many events in a rapid sequence. Horizontal Delay. Use delay when you want to acquire a signal at a significant time interval after the trigger point. Toggle delay on and off to quickly compare the signal at two different points in time. Optical-to-Electrical Converter. CSA7000B Series only. Test optical signals using the integrated optical-to-electrical Converter and a fully calibrated signal path. Recovered clock and data signals are available. Optical reference receivers are available for selected optical communications standards. SignalProcessing Features Average, Envelope, and Hi Res Acquisition. Use Average acquisition mode to remove uncorrelated noise from your signal. Use Envelope to capture and display the maximum variation of the signal. Use Hi Res to increase vertical resolution for lower bandwidth signals. Waveform Math. Set up simple math waveforms using the basic arithmetic functions or create more advanced math waveforms using the math expression editor. Waveform expressions can even contain measurement results and other math waveforms. Spectral Analysis. Display spectral magnitude and phase waveforms based on your time-domain acquisitions. Control the instrument using the traditional spectrum Analyzer controls such as span and center frequency. Display Features Color LCD Display. Identify and differentiate waveforms easily with color coding. Waveforms, readouts, and inputs are color matched to increase productivity and reduce operating errors. Enhance visualization of waveforms with color grading. Digital Phosphor. The instrument can clearly display intensity modulation in your signals. The instrument automatically overlays subsequent acquisitions and then decays them to simulate the writing and decay of the phosphor in an analog instrument CRT. The feature results in an intensity-graded or color-graded waveform display that shows the information in the intensity modulation. Fit to Screen. The Digital Phosphor technology performs the compression required to represent all record points on the screen, even at the maximum record length settings. MultiView Zoom. To take advantage of the full resolution of the instrument you can zoom in on a waveform to see the fine details. Both vertical and horizontal zoom functions are available. Zoomed waveforms can be aligned, locked, and automatically scrolled. Measurement Features Cursors. Use cursors to take simple voltage, time, and frequency measurements. Automatic Measurements. Choose from a large palette of amplitude, time, and histogram measurements. You can customize the measurements by changing reference levels or by adding measurement gating. Mask Testing. Optional on TDS7000B Series, Provides mask testing for verifying compliance to optical /CSA7000B Series only) and electrical standards. Optical mask testing uses integrated reference receivers. Trigger Features Simple and Advanced Trigger Types. Choose simple edge trigger or choose from eight advanced trigger types to help you capture a specific signal fault or event. Dual Triggers. Use the A (main) trigger system alone or add the B trigger to capture more complex events. You can use the A and B triggers together to set up a delay-by-time or delay-by-events trigger condition. Comm Triggers. Optional on TDS7000B Series, Use comm triggers to trigger on communication signals. Serial Triggers. Optional on TDS7000B Series, Use serial triggers to trigger on serial pattern data. Recovered Clock and Data Triggers. Use recovered clock and data internally to trigger your waveforms. They are also available externally (CSA7000B Series only). Convenience Features Autoset. Use Autoset to quickly set up the vertical, horizontal, and trigger controls for a usable display. If a standard mask is active (optional on TDS7000B Series), Autoset adjusts the selected waveform to match the mask, if possible. Touch Screen Interface. You can operate all instrument functions (except the power switch and the touch screen enable/disable switch) from the touch screen interface. If convenient, you can also install a mouse and keyboard to use the interface. Toolbar or Menu Bar. You can choose a toolbar operating mode that is optimized for use with the touch screen, or a PC-style menu bar operating mode that is optimized for use with a mouse.
