Information

The TDS 620A 640A, & 644A are portable, four-channeldigitizing oscilloscopes suitable for use in a variety of test and measurement applications and systems. Key features include: • A maximum digitizing rate of 2 GS/s on each of the full-featured channels (four on the TDS 640A and 644A, two on the(TDS 620A) simultaneously with an analog bandwidth of 500 MHz. • Four input channels, each with 8-bit vertical resolution, and each with a record length of 2,000 samples and 8-bit vertical resolution. • Extensive triggering capabilities: such as edge, logic, and glitch. Video trigger (Option 05, is also available. The video trigger modes are NTSC, SECAM, PAL, HDTV, and FlexFormatTM (user definable format). • Acquisition modes such as sample, envelope, and average. • A full complement of advanced functions, like continuously-updated measurements, results and local pass/fail decision making. • Specialized display modes, such as variable persistence with color grading, dot or vector mode, sin(x)/x or linear display filters, and user selectable color pallettes. The "Fit to Screen" features compresses the entire waveform record to fit on the screen. • A unique graphical user Interface (GUI), an on-board help mode, and a logical front-panel layout which combine to deliver a new standard in usability. • Full GPIB Software programmability. Hardcopy output using GPIB, RS-232, or Centronics ports. RS-232 and Centronics are standard on the TDS 644A and optional, as option 13, on the TDS 620A and 640A. • VGA output for driving remote monitors. • A 1.44 Mbyte, DOS 3.3 or later-compatible, floppy disk drive (option 1F on the TDS 620A and 640A) and NVRAM mass storage for saving waveforms, hardcopies, and Oscilloscope setups. • On the TDS 644A a color display for distinguishing among waveforms, their measurements, and associated text. User Interface Use a combination of front-panel buttons, knobs, and on-screen menus to control the oscilloscope's many functions. The front-panel controls are grouped according to function: vertical, horizontal, trigger, and special. Set a function you adjust often, such as vertical positioning or the time base setting, directly by its own front-panel knob. Set functions which you change less often, such as vertical coupling and horizontal mode, indirectly using selected menus. Menus Pressing one (sometimes two) front-panel button(s), such as vertical menu, displays a main menu of related functions, such as coupling, bandwidth, etc., at the bottom of the screen. Pressing a main-menu button, such as coupling, displays a side menu of settings for that function, such as AC, DC, or GND (ground) coupling, at the right side of the screen. Pressing a side-menu button selects a setting such as DC. Indicators On-screen readouts help you keep track of the settings for various functions, such as vertical and horizontal scale and trigger level. Some readouts use the cursors or the automatic parameter extraction feature (called measure) to display the results of measurements made or the status of the instrument. General Purpose Knob Assign the general purpose knob to adjust a selected parameter function. More quickly change parameters by toggling the SHIFT button. Use the same method as for selecting a function, except the final side-menu selection assigns the general purpose knob to adjust some function, such as the position of measurement cursors on screen, or the setting for a channel's fine gain. GUI The user Interface also makes use of a GUI, or Graphical User Interface, to make setting functions and interpreting the display more intuitive. Some menus and status are displayed using iconic representations of function settings such as those shown here for full, 100 MHz, and 20 MHz bandwidth. Such icons allow you to more readily determine status or the available settings.
