(See Chapter 8.) $XWRPDWLF?&DOLEUDWLRQThe oscilloscopes automatic calibration ensures an overall vertical accuracy of typically 1% of full scale. Vertical gain and offset calibration take place each time the volts/div

2、 setting is modified. In addition, periodic calibration is performed to ensure long-term stability at the current setting. LVSOD?6VWHPThe displays interactive, user-friendly interface is controlled by push-buttons and knobs (see Chapter 4). The large, 12.5 17.5 cm (nine-inch diagonal) screen shows w

3、aveforms and data with enhanced resolution on a variety of grid styles (see Chapter 11). Up to four waveforms can be displayed at once, while the parameters controlling signal acquisition are simultaneously reported. The screen presents internal status and measurement results, as well as operational

5、 front- panel layout and controls that will be familiar to users of analog oscilloscopes. Rapid instrument response and instant representation of waveforms on the high-resolution screen add to this impression. Four front-panel setups can be stored internally and recalled either manually or by remote

The oscilloscope has also been designed for remote control operation in automated testing and computer-aided

7、 measurement applications operations described in the Remote Control Manual. The entire measurement process, including cursor and pulse-parameter settings, dynamic modification of front-panel settings, and display organization, is controlled through the rear-panel GPIB (IEEE-488) and RS-232-C ports
