Relative time correlation error (typical)

Typical measured relative time correlation error between modules in the same instrument

Includes typical jitter, slot-to-slot skew, and probe-to-probe variations to provide a simple, overall, typical value. Assumes standard accessory probes are used.

For long-term (> 1 s) time interval measurements between modules add 0.01% of the delta time between the absolute time measurements to the relative time correlation error to account for the inaccuracy of the CLK10 source.

In the Waveform window, triggers are always marked immediately except when delayed to the first sample. In the Listing window, triggers are always marked on the next sample period following their occurrence.

Clk represents the time to the next master clock at the destination logic analyzer module. In the normal internal clock mode, this represents the delta time to the next sample clock. In the external clock mode, this represents the time to the next master clock generated by the setup of the clocking state machine and the supplied target system clocks and qualification data.

Signals 1 and 2 (ECLTRG0, 1) are limited to a broadcast mode of operation where only one source is allowed to drive the signal node at any one time. The signal source can be used to drive any combination of destinations.

All system trigger and signal input latencies are measured from the falling edge transition (active/true low) with signals in the wired-OR configuration.

Smpl represents the time from the event to the next valid data sample at the LA probe tip. In the normal internal clock mode, this represents the delta time to the next sample clock. In the MagniVu i n ternal clock mode, this represents 500 ps or less. In the external clock mode, this represents the time to the next master clock generated by the setup of the clocking state machine and the supplied target system clocks and qualification data.

All Signal output latencies are validated to the rising edge of an active (true) high output.

Block Level Description

The following paragraphs provide a high-level overview of the major components of the TLA715 Portable Mainframe. Refer to Figure 3--1 while reading the following paragraphs.

Controller Board

TLA715 Dual Monitor Portable Mainframe Service Manual

The controller board provides the portable mainframe with a high-performance PC-based controller architecture, including graphics and I/O, and interfaces to the backplane bus and the front panel. The controller board mounts vertically on the left side of the instrument and connects to the back of the backplane. The controller provides signals to the rear panel and front panel interface.

3- 1

Theory of Operation

The controller uses a standard Intel Pentium III microprocessor using the 815E chip-set. The controller has a 733 MHz Pentium III processor with up to 512 MB of SDRAM, 16 KB of Li instruction cache, 16 KB of LI data cache, 256 KB of L2 cache, and 8 MB of flashed-based BIOS.

A ECP/EPP Centronics-compatible parallel port, two USB ports, and two 16550-based serial RS-232 COM ports (one external) support standard PC-based I/O peripherals.

A Silicon Motion Lynx3DM SVGA/XGA display controller with up to 4 MB of internal DRAM supports the flat panel LCD display and an external SVGA port. The 815E chip-set provides and additional SVGA/XGA output port.

The backplane interface appears as a standard PCI device to the PC-based controller. The PCI-to-Backplane interface is managed by a Tektronix-designed ADG343 CMOS ASIC which includes support for DMA transfers with FIFO, IRQ management, programmable byte swapping, backplane address space management and windowing (A16, A24, and A32 space), backplane arbitration, and MODID control lines.

Backplane

Front Panel Interface

The backplane trigger lines are managed by the Tektronix-designed Backplane Trigger Crossbar (VTC) ASIC. The VTC ASIC cross-connects any of the ten trigger lines (ECL and TTL) to any of the four BNC ports on the rear I/O panel of the mainframe. The four BNC ports accommodate two inputs (System Trigger In and External Signal In) and two outputs (System Trigger Out and External Signal Out). The VTC ASIC also supports several standard trigger protocols (including START/STOP protocol), which support a synchronous start of all modules to System Time Zero (STZ), and several custom features including time interpolation to support the VTC ASIC in individual module applications.

The backplane supports up to four single-wide slots, where most modules require two slots. The backplane connects the power supply to the rest of the instrument. It also distributes the 10 MHz system clock and supports all communication to, from, and between the modules, including real time intermodule communications.

The front panel interface assembly interacts with the system controller, LCD flat panel display, floppy disk drive, front panel keypad and trackball, USB ports, mouse, and keyboard. Dual 50-pin cables connect the front panel interface board to the internal slot-0 controller. The interface also supplies a speaker for the PC.

TLA715 Dual Monitor Portable Mainframe Service Manual

Theory of Operation

LCD Display

Front Panel Controls

The internal display is a 10.4-inch diagonal Active Matrix Thin-Film-Transistor (TFT) liquid crystal display with a built-in back light similar to those found in many notebook PCs. The color-cathode fluorescent back light can be dimmed to 60% of its value via a custom Tektronix screen saver or mainframe utilities applet to extend its life and to prevent burning of the TFT LCD screen. The LCD has an external DC switching regulator board to provide the back light high voltage and a display adapter board which supports interfacing from the front panel interface board to the LCD display.

The front panel key pad consists of a Hex keypad and a partial QWERTY keypad. The front panel keypads are active simultaneously with an optional external keyboard through an MC68HC705B16 front panel processor. The front panel processor combines the two devices to generate and receive standard keyboard scan codes from the system controller.

The front panel knobs include the following controls:

H Detented horizontal size control

H Detented vertical size control

H Nondetented horizontal position control

H Nondetented vertical position control

Hard Disk Drives

H A nondetented multifunctional knob

A second MC68HC705B16 control panel processor and a custom WIN32 knob API (DLL and VxD drivers) control the front panel knobs.

The trackball pointing device is a standard, off-the-shelf OEM PC pointing device mechanically integrated into the mainframe. The trackball is simultaneously active with an external mouse through the USB. The external mouse connects directly to the controller through a PS2 interface.

The hard disk drives (HDD) are standard 2.5-inch IDE drives which interface directly to the system controller through an Enhanced Integrated Device Electronics (IDE) extension of the PCI bus. The main HDD is easily removable from the mainframe without removing any covers. The HDD is available in two configurations: minimum and maximum (the sizes depend on the availability of the hard disk drives).

The mainframe is electrically capable of accepting dual master-slave IDE HDD configurations for a total of four drives (or other HDD devices) but is mechanically limited to mounting two drives. The CD-ROM uses the A slot on the secondary IDE interface which reduces the number of HDD devices to three.
