this specification section contains tabular listings of the electrical, environmental, and physical characteristics of the 7854 oscilloscope with waveform calculator.refer a qualified service person to the performance check proiedure in the calibration section of the 7854 service manual to verify the electrical performance of your instrument.

also included in this section are:1 instrument shipping instructions;2. a list of standard accessories for the 7854 oscilloscope;3. the 7000-series oscilloscope system specifications; and4. a table of plug-in unit compatibilities.the 7854 oscilloscope system can be operated in any of three distinct display modes-scope. stored, or both-as se-lected with the keys located in the crt display blocks on either the measurement or waveform calculalor keyboards. these display modes are defined as follows: (a) scope mode-real-time waveform and readout displays supplied by the se-lected plug-in units (as in conventional oscilloscopes). (b) stored mode-stored waveform and alphanumeric character displays supplied by" the internal processor of the 7854 oscilloscope. (c) both; mode-mixed displays of the real-time waveforms from the plug-in unrts with the stored waveforms and alphanumeric character displays supplied from the internal processor

other features of your 7854 oscilloscope system are introduced in the remainder of this section. in addition, this section includes the following:1. brief desc-riptions of each control, connector, key, and indicator;2. installation instructions including power-up conditions; and3. a glossary of terms used throughout this manual.

7854 features

the tektronix 7854 oscilloscope with waveform calculator combines the features of a high-performance plug-in oscilloscope with a waveform-oriented dedicated-function digital processor.

the 7854 accepts tektronix 7000-series plug-in units for display control. the flexibility and variety provided by the wide line of plug-in units available allow the system to accommodate many measurement applications. the left pair of plug-in compartments are used for the vertical deflection of the real-time signal and the right pair are for thehorizontal deflection. electronic switching between each pair will produce multi-trace - real-time vertical or horizontal displays.

in addition, the waveforrn.processor provides equivalent-time sampled tilgitizing of waveforms to 400 megahertz equivalent-time bandwidth. the processor can be operated from either keyboard (front-panel measurement keyboard or detachable waveform calculator keyboard) or remcy over the gpib (general purpose interface bus). by changing the resolution of the waveform memory in the standard version of the 7854 oscilloscope, up to 16 wavefnrrns can be stored in memory: up to 9 of these can be displayed at one time. a mixed (both) mode is provided to display both the real-time waveforms and the stored waveforms for comparison or measurement.

cursors are provided for the stored waveforms to delimit or identify portions of the waveform to be measured. these cursors are generated by the processor and can be manually positioned by executing the appropriate commands from the keyboard(s), automatically positioned througn execution of a stored program, or remoy positioned from the gpib controller. some of the dedrcated functions (e.g., width, rise, itrp, etc.) are cursor-dependent. the cursor coordinates (or relative coordinates) are provided on the display in the stored or both modes.

specific characteristics of the stored display can be se-lected with the keyboards or over the gpib. the waveform calculator provides display control to vertically or horizontally expand the stored waveform; display any stored waveform versus another in x-y mode, or versus time in y-t mode; display the stored waveform as individual points, or with vectors drawn between points. also, functions are provided to manipulate the entire stored waveform. for example, any stored waveform can be either vertically or horizontally positioned without affecting the absolute voltave values; or any stored waveform can be differentiated, integrated, or smoothed and the resulting waveform displayed.

programming, consisting of a terms of commands stored for later execution, is available to simplify measurements which must be repeated. editing and execution is controlled either from the waveform calculator or the gpib
