    This high level oscilloscope is equipped with a side carrying handle for easy portability from place to place. This Oscilloscope solves measurement problems equally well on a designer's bench or in a programmable test system. The unit has flexible triggering features & an 8 Channel display. This unit supports 3 vertical amp plug ins. This means you can acquire up to eight channels of data at 300 MHz or six channels of data at 600 MHz, or up to 3 channels of data at 1 GHz. Eight traces can be displayed at 1 time so you can get the whole picture at one time. The 11401 combines wide bandwidth with 10-ps horizontal resolution & 10-bit vertical resolution. Multiple records of up to 10,240 points can be acquired using this Tektronix 11401 Scope. Waveforms can be stored on board the scope for analysis at a later time. This scope brings outstanding versatility with a measurement system & waveform processing functioning which leads to quick solutions at a variety of voltages, times, areas, & energy problem situations. Fast overdrive recovery & up to 2000 divisions of dynamic range give the Tek 11401 Scope the power to look at the smallest detail on difficult to capture waveforms. This Digitizing Scope uses simple parallel menus & touch screen capabilities to give easy access to their measurement & display features. There are only a few buttons and knobs which are found on the face of the 11401 Scope. All of the controls are found directly on screen and the system will only present control selections when they are valid and / or useful. An autoset function allows the scope to be set up for the operator based on the signal characteristics of the selected trace. The most commonly used functions are never deeper then the 2nd menu & pop up menus present choices & fold down when the selections are made. This unit is one of the most accurate high bandwidth scopes on the market. The combination of timing accuracy inherent in digital time bases with 1% vertical accuracy is incredible. The enhanced accuracy feature prompts the user to start self calibration routines when the temperature & configuration changes warrant it. The signal & probe power connections are all made at the amplifier input, eliminating extra probe power lines. The unit supports as many active probes as their is functioning channels. The termination impedance is no longer an issue, as the Tektronix 11401 sets it automatically. The full range of measurement needs is covered with this Scope: Waveform Processing, Pulse Parameter Analysis, Cursor Functions, & Trigger to Trigger Measurements. Users can set proximal, distal, & medial levels to customize timing measurements. Up to 6 measurement results can be displayed continuously updated as data changes. Higher Bandwidth, better resolution, more accuracy, more versatility, hardware & software modular, ease in use and to service, makes the Tektronix 11401 one of the Cadillacs of Digitizing Oscilloscopes. As mentioned above, most of the features & controls are located in the touch screen functioning. The front of the Scope and the 2 plug ins do have a few controls & connection devices which can be inventoried. To the right side of the Digital Display Screen are 6 buttons and 2 adjustment knobs. The Knobs are unlabeled but the buttons are inventoried as: Waveform, Trigger, Measure, Store / Recall, Utility, & Touch Panel On / Off. Just above the Plug in Area are 4 Buttons (Digitizer Run / Stop, Autoset, Hardcopy, Enhanced Accuracy. There is also a Calibrator Jack, a Calibrator Screw Down Connector, & the Power switch located above the Plug in Area.

  • Plug-In Modularity
  • Waveform Processing and Automatic Pulse Parameters
  • Multiple 10,240-Point Waveform Records
  • Accepts Differential, High-Impedance and 50-O-Input Amplifiers
  • Greatly Simplified Access to Features
  • Fully Programmable via GPIB and RS-232C Specifications The 11401 is the first in a new line of digitizing oscilloscopes. These versatile scopes, with their array of new supporting plug-ins and probes, solve measurement problems equally well on a designer's bench or in a programmable test system. Digital designers will benefit from flexible triggering features and an eight-channel display. Analog and power-supply designers can apply extensive waveform processing to signals acquired through high-performance differential and single-ended amplifiers. 11000-Series digitizing scopes can follow your designs into production. Full programmability via either IEEE-488 or RS-232C and features like a DMA controller for fast waveform transfers make these scopes a perfect fit for systems. 11000-Series digitizing oscilloscopes set new standards in performance.
