TDS6000 Series Service Manual

Processor System.

The processor system contains two processor boards with

microprocessors that control the entire oscilloscope. The basic configuration
supports four input channels labeled Ch1 through Ch 4, provides an external
trigger input, a trigger output, a Ch3 signal output, and a probe compensation
output.

Each acquisition channel is equipped with a processor that uses its own host
interface to interface to the GCS which in turn communicates with the command
interface processor over the multiplexed address/data nibble bus.

Waveforms and menus are displayed on a 10.4 inch, color, active-matrix LCD
display with touch panel.

Display System.

Text and waveforms are processed by different parts of the

display circuitry. The display system (display adapter board and inverter board)
sends the text and waveform information to the display panel.

Touch Panel.

The display board sends information from the touch panel to the

processor. Any changes in settings are reported to the processor system.

The NLX board reads the front-panel switches and encoders. Any changes in
their settings are reported to the processor system. The NLX board also turns the
LEDs on and off.

Menu Switches.

Front-panel menu switches are also read by the NLX board. The

touch screen processor sends any changes in menu selections to the NLX
processor system. The

ON/STBY

switch passes through the CPU board to the

NLX board. The NLX board creates the signal sent to the power supply to toggle
power.

Floppy Drive.

The floppy drive provides access to stored waveform data and

software to customize your oscilloscope.

CPU Board.

The CPU board provides fast access to the Acquisition board and the

display system. The NLX board reads the front-panel switches and encoders and
implements any changes requested by their settings. The CPU board provides a
GPIB interface through a rear panel connector.

NLX Board.

The NLX board provides standard Windows functionality and I/O

port interfaces to the rear panel.
