1.3 Features
Software. A 32-bit control computer running a real-time operating system provides display, I/O
and system memory functions for the instrument. The instrument also contains a dedicated
floating-point DSP, FPGA and memories to perform the measurement functions. Software updates
are easily made using the rear-panel Ethernet port.
Auto-Setup. The instrument will automatically select a vertical scale, vertical offset, timebase,
holdoff and trigger level to display at least one pulse period at full amplitude of the full waveform.
Menu-Driven Operation. Setup and control of the instrument is menu-driven to simplify
operation. User-selected parameters appear in a menu to the right of the waveform, together with
applicable variables. Selections are arranged opposite adjacent ―soft keys‖ that select parameters
and activate data entry controls. Required numerical values are entered through the keypad or
with flexible increment/decrement using the ▲▼arrow keys.
Color Display. Waveforms, control menus, measurement values and related text are displayed on a
4.0-inch diagonal, 320 x 240 pixel color LCD. The display has an adjustable brightness CCFL
backlit, and the built-in ―screen saver‖ function may be used to dim the backlight automatically to
further extend lamp life.
