Hardcopy On Anomaly On Off When On, the oscilloscope sends an image of the screen to the hard copy device or floppy file if there is a waveform anom- aly on any channel. Wfms To Disk On Anomaly On Off When On, the oscilloscope saves the anomalous wave- form(s) data to the floppy disk drive. Highlight Entire Wfm Highlights the entire anomalous waveform. Highlight Anomaly Highlights just the anomalous data in a waveform. WaveAlert� Waveform Anomaly Detection. WaveAlert provides a way to detect when a waveform deviates from a steady-state condition. WaveAlert monitors the current waveform acquisition and compares it to the previous waveform acquisition. If the current acquisition exceeds the comparison tolerance, the oscilloscope considers the current acquisition as an anomaly and responds by stopping acquisitions, emitting a beep, saving the anomalous waveform to a disk file, printing the screen image to a hard copy device, or any combination of the above. Refer to the TDS3000B Series Digital Phosphor Oscilloscope User Manual for more information.

Before using the e*Scope feature, you must set your oscilloscope Ethernet network settings. The TDS3000B Series Digital Phosphor Oscilloscope User Manual, Appendix G, Ethernet Setup, describes how to enter the Ethernet network parameters for your oscilloscope. Accessing e*Scope After your instrument is set up with the correct ethernet settings, you are ready to access that instrument over the Internet. To access you instrument’s e*Scope server, do the following steps: 1 On a PC or work station, open a network browser program. 2 In the Location or Address field (where you normally enter a URL), type in the IP address of the TDS3000B instrument to which you want to connect. For example, 188.121.212.107. Do not precede the IP address with any characters. Then press the Return key. 3 The browser program loads the instrument’s e*Scope Web-based Remote Control home page, which is an image of the screen contents when your browser accessed the instrument. �� e*Scope Web-based Remote Control e*Scope introduces the next generation of oscilloscope functionality. With e*Scope you can access any Internet- connected TDS3000B Series oscilloscope from a browser on your work station, PC, or laptop computer. No matter where you are, your TDS3000B is as close as the nearest browser! There are two levels to e*Scope: basic and advanced. The basic level, which is hosted on the oscilloscope, lets you view a screen image of the current acquisition, save or load waveform and setup files, and remotely control the oscilloscope using the oscilloscope programming commands. The advanced level, which is hosted on your system, provides a graphical user interface to remotely control the oscilloscope. To obtain the advanced level software, go to the Tektronix TDS3000B website and download the web-based remote control software. NOTE. You can also use e*Scope on TDS3000 Series oscilloscopes that are equipped with a TDS3EM Ethernet communication module and are running firmware version 3 or above.
