11000-Series High Performance Laboratory Oscilloscopes

The Tektronix 11000-Series is a powerful set of analysis tools that feature simplification and automation of the entire measurement and analysis process.  Accuracy, sensitivity. bandwidth, offset, and overdrive recovery are provided by a well-planned instrument family having plug-in versatility and performance.   Multi-processor architecture allows fro simultaneous display of up to eight waveforms, and up to six dynamic, "live" measurement readouts.  The automation needs of scientific and production environments are easily met by integrating these instruments into a measurement system through RS-232C or GPIB interfaces.

The Digitizing Signal Analyzer (DSA) Series incorporates a dedicated digital signal processor (DSP) making it the most powerful instrument in the 11000 series.  The dedicated DSP allows simultaneous real-time FFT and time-domain display, fast averaging at 180 waveforms/second, signal dejitter, and more.

The Communications Signal Analyzer (CSA) series offers signal analysis and the powerful measurement capabilities required to analyze high-speed digital communications signals.  Features of the CSA404 include histograms, mask testing, and a color-graded display; allowing you to perform accurate measurements such as jitter, noise, and phase.

11000-Series Plug-In Amplifiers:

Wide bandwidth, high accuracy, clean response, low noise, and calibrated dc-offset with fast overdrive recovery characterize these amplifier plug-in units.  Control of the 11000 series is accomplished through the mainframe either manually or over the GPIB or RS-232C bus.  Each input features the TekProbe interface which supplies power for active probes, and provides probe ID through a built-in serial interface.

Which amplifier to chose?  They're all fast precision amps, but bandwidth costs in terms of flexibility; The 11A34 and 11A32 offer 300 to 400 MHz, 1 mV to 10V per division deflection factor, and selectable 1Mohm / 50 ohm input impedance.  The 11A52 will bring you as high as 600 MHz with 50 ohms input impedance and software compensation to maintain 1 mV to 10 V per division deflection.  The 11A71 and 11A72 can get as high as 1000 MHz with 50 ohm impedance, but sacrifice dynamic range at 10 mV to 1 V per division.
