    Live Display of Up to Eight Traces

    The 11401 and 11402 each support three vertical amplifier plug-ins.  This means you can acquire up to eight channels of data at 300 MHz, up to six channels of data at 1 GHz.  You can, of course, mix and match the plug-ins to design the system that works best for you.  The update rate is so fast that the 11401 and 11402 have the look and feel of analog scopes.

    High Vertical and Horizontal Resolution

    The 11401 and 11402 uniquely combine high-bandwidth with 10-ps horizontal resolution and 10-bit vertical resolution (vertical resolution can be increased to 14 bits when signals are averaged).  Other vendors have made a tradeoff: bandwidth for vertical resolution, or vertical resolution for bandwidth.  The 11401/11402 give you both for making demanding voltage and timing measurements in one box.   In addition, the 11401/11402s trigger-to-trigger measurement feature delivers 200-ps precision on single-shot time A->B measurements and can even provide 10-ps precision with averaging.  Trigger-to-trigger measurements of this kind are only available on the 11401/11402 and a few expensive, standalone counter/timers.  Also, window records can be used to increase horizontal resolution on specific segments of main records to provide a clear picture of signal details.

    Multiple Long Record Lengths

    The 11401/11402 can acquire multiple records of up to 10,240 points each.  No other scope can capture as much data at once on repetitive waveforms.  The mainframes can contain up to 102,400 points of waveform memory with option 2D.  Long records and large strorage capacity combine to let users gather data over relatively long periods of time with high resolution and improve measurement accuracy.  One doesnt need a computer to log waveform data.  Waveforms can be stored in the scope for later analysis.

    Versatility for a Wide Range of Applications

    Five plug-ins and new probes bring outstanding versatility to the 11401/11402.  The measurement-system and waveform-processing functions lead to quick solutions to a wide variety of voltage, time, area, and energy problems.  These scopes can process and measure  signals from high-bandwidth 50-ohm amplifiers, high-impedance amplifiers, and differential amplifiers.  1-mV sensitivity and 500 V maximum input voltage let users capture small signals from transducers or monitor ac power lines.  Fast overdrive recovery and up to 2000 divisions of dynamic range give the 11401/11402 the power to look at even the smallest detail on difficult-to-capture waveforms.

    Unparalleled Ease of Use

    The 11401 and 11402 use simple parallel menus and touch screen to give easy access to their measurement and display features.  All but a few of the buttons and knobs have been eliminated in favor of a system that presents selections when they are valid and/or useful.  An Autoset function sets up the scope for you based upon the signal characteristics of the selected trace.  This function can be activated from the probe tip, allowing for hands-off operation of the scope.   Autoset frees the operator to concentrate on the measurement problem and the probe connection.  The most commonly used functions are no deeper than a second menu level.   Icons let you assign the knobs to waveform size and position no matter what operating mode you are in.  Pop-up menus present choices and fold down when thos selections are made.  One-button hardcopy generation is made possible by software drivers compatible with low-cost Epson dot-matrix printers.  Overall, the operation of the 11401/11402 is intuitive.  The instrument can be used easily, even if it is not used every day.  Acquisition, measurement, and documentation is as simple as six touches: Autoset, measure, measurements, rise, exit, hard copy.  It doesnt get any simpler.

    Plug-In Modularity

    The 11401 and 11402 accept five different vertical amplifiers.  Each scope will accept three of these amplifiers in its plug-in compartments.  You can configure a scope to meet your particular needs.

    The Most Accurate Instruments of Their Kind

    The 11402 and 11402 are the most accurate high-bandwidth scopes on the market.  They combine the timing accuracy inherent in digital time bases with 1% vertical accuracy.  The Enhance Accuracy feature ensures that the highest accuracy is maintained.  The scope prompts the user to start the routines whenever temperature or configuration changes warrant it.  You can even assign the 11401/11402 to start Enhanced Accuracy routines automatically.  Timebase accuracy is 100 ps +0.002% of the measured time interval.  The 11401 and 11402s accurate measurements can replace dedicated counter/timers and ac voltmeters.   Devices and subassemblies can be tested to tighter tolerances, improving end product performance and quality.

    Probe Interface

    Weve set a new standard for probe interfacing.   Signal and probe-power connections are all made at the amplifier input, eliminating extra probe power lines.  We can support as many active probes as you have channels.   A smart serial interface between probe and scope let you stop worrying about the proper termination impedance; it is set automatically.  You can Autoset the scope or sequence through a series of front-panel set-ups all from the probe-ID button.  This leaves your hands free to probe your circuit.  A full complement of active and passive probes with this new interface is ready to assist in the solution to your measurement problems.

    Choose Your Computer Interface

    The 11401 and 11402 have both IEEE-488 and RS_232C interfaces as standard features for data transfer and instrument control.  The RS-232C port lets you control the instrument with a PC, upload and download waveforms from a workstation or mainframe, or run diagnostics over a modem.  GPIB and RS232C menus let you match interface parameters with a controller, modem, or host. If speed is a consideration, the parallel interface provided by the IEEE-488 interface should be used.   A DMA option can be added to speed up GPIB transfers even further.  Whichever bus is chosen, the instruments respond to the logical set of Tektronix Standard Codes and Formats commands that make it easy to writ your test procedures.

    Accurate, Automatic Measurements

    The only reason oscilloscopes exist is for making measurements.  The 11401 and 11402 can perform waveform-processing functions, pulse-parameter analysis, cursor functions, and trigger-to-trigger measurements that combine to can cover a full range of measurement needs.  A special annotation mode shows where measurements are being made on the trace so users can feel confident that they are on target.  Dot cursors can be split between two waveforms to make propagation-delay measurements or to compare voltages.  Measurement zones can be set to limit the automatic measurement to a portion of the displayed trace.  Users can set proximal, distal, and mesial levels to customize timing measurements.  Up to six measurements can be displayed at once and continuously updated as the data changes.  This lets users make adjustments and see the results quicker than ever before.  A direct hard-copy output is provided that includes time and date of the measurement for archiving.

    Windows - In addition to the main record, one or two window records may be displayed.  The window records may be of different length (duration) and may have smaller time/div than the main record.  If two window records are used, they have the same duration and time/div settings, and can be positioned independently.

    Window Record Positioning - The window records are positioned relative to a window trigger point, which may be positioned relative to the main records trigger point delayed by either time or events.

    Main->Window Time Measurement - The time between the MAIN record trigger and the WINDOW trigger can be measured precisely, even if each trigger occurs only once.  Repetitive events allow this measurement to be averaged fo better resolution and accuracy.  Single trigger precision: 200 ps.  Repetitive precision: 10 ps, after 100 averages.  Accuracy:  250 ps +0.002% of record duration.
