power connector for additional front end signal conditioning functions like high
input-impedance real-time probes.
Processor System.
The processor system contains a dual Wintel/Power PCC. The
basic instrument configuration supports up to eight channels labeled Ch1 through
Ch 8, provides two external trigger inputs for direct and prescaled triggering
through built–in prescaler and is able to support two optional internal trigger
sources associated with the large slot channels mapped onto electrical channels 1
and 2.
Color LCD display Active-matrix touch panel.
Display System.
Text and waveforms are processed by different parts of the
display circuitry. The display system sends the text and waveform information to
the display panel.
Touch Panel.
The Display board sends information to the processor. Any changes
in their settings are reported to the processor system.
The front panel board reads the front-panel switches and knob sensors. Any
changes in their settings are reported to the processor system. The front panel
board also turns the LEDs on and off and generates the bell signal.
Front-panel menu switches are also read by the PPC processor board. The
processor sends any changes in menu selections to the processor system. The
ON/STBY switch is one of the menu switches. However, it is not read by the
front panel board, but passes through the front panel board to the low voltage
power supply.
The hard drive and CD Rom provides access to stored waveform data and to load
software to customized your instrument with your measurement needs. The
GPIB allows for external control of the instrument.
You can make hardcopies on the GPIB, RS-232, and Centronics ports. Other
ports from the front panel board: PC cardbus x 2, cal adjust lock.
Outputs from the NLX board: SVGA, USB (1), sound, serial (2), parallel,
Ethernet, mouse, keyboard.
The low voltage power supply is a switching power converter with active power
factor control. It supplies power to all of the circuitry in the instrument.
The principal POWER switch, located on the rear panel, controls all power to the
instrument including the Low Voltage Power Supply. The ON/STBY switch,
