Key Features

The PXI-1000 combines a high-performance 8-slot PXI backplane with a
high-output power supply and a structural design that has been optimized
for maximum usability in a wide range of applications. The mainframe’s
modular design ensures the highest lev e l of maintainability resulting in a
very low mean time to repair (MTTR). The PXI-1000 fully complies with
the PXI Specification, Revision 1.0, offering advanced timing and
synchronization features.

Power Cable Reference Standards

Power Cables (Continued)

The key features of the PXI-1000 include:

• PXI and CompactPCI (PICMG 2.0 R 2.1) module compatibility

• Compact 3U-sized, 8-slot chassis

• 300 W of usable power

• Universal AC input: auto-voltage and auto-frequency ranging

• Over-current protection via push-reset circuit breaker (no loose fuses
to replace)

• Removable modular power supply with MTBF of 90,000 hours

• Remote power status and inhibit via a rear panel connector

• On/Off (Standby) switch located on the front panel for easy access

PXI-1000 Backplane Overview

Interoperability with CompactPCI

The PXI-1000 backplane is interoperable with PXI-compatible products
and standard CompactPCI products. This is an important feature, as many
PXI-compatible systems may not require components that do not
implement PXI-specific features. For example, you may want to use a
standard CompactPCI network interface card in a PXI chassis.

The signals on the P1 connector of the backplane meet the requirements of
the CompactPCI specification for both the periph eral and system mo du les.

The PXI-specific signals are located on P2 and are only found on the
signals that are reserved or not used in the CompactPCI 64-bit
specification. Therefore, all modules that meet the requirements of the
CompactPCI 64-bit specification will function in the PXI-1000.

System Controller Slot

The System Controller slot is located in Slot 1 o f th e ch assis as def i ned by
the PXI specification. It has three controller expansion slots, which are
used for system controller modules that are wider than one slot. As defined
in the PXI specification, these slots allow the controller to expand to the left
to prevent the controller from using up peripheral slots.

Star Trigger Slot

The Star Trigger (ST) slot is located at Slot 2. This slot has a dedicated
trigger line between each peripheral slot (see Figure 1-3). This slot is
intended for modules with ST functionality that can provide individual
triggers to all other peripherals. However, if you do not require advanced
trigger functionality, you can instal l any standard peripheral module into
this slot.

Peripheral Slots

There are seven peripheral slots including the Star Trigger controller slot.

National Instruments Corporation 1-5 PXI-1000 User Manual

Chapter 1 Getting Started

Local Bus

The PXI backplane’s local bus is a daisy-chained bus that connects each
peripheral slot with its adjacent peripheral slots to the left and right, as
shown in Figure 1-3.

For example, a given peripheral slot’s right local bus connects to the
adjacent slot’ s left local bus and so on. Each local b us is 13 lines wide an d
can pass analog signals between cards or provide a high-speed side-band
communication path that does not affect the PXI bandwidth.

Local Bus signals may range from high-speed TTL signals to analog
signals as high as 42 V. Initialization software keys adjacent boards to
prohibit the use of incompatible boards. This software uses the
configuration information specific to each peripheral board to evaluate
compatibility. This method is a flexible way to define local bus
functionality that is not limited by hardware keying.

Trigger Bus

The eight PXI trigger lines are bused to each slot. You can use the trigger
lines in a variety of ways. For exampl e, you can use t riggers to synchronize
the operation of several diff erent PXI peri pheral modules. In other
applications, one module can control carefully timed sequences of

operations performed on other modules in the system. Modules can pass
triggers to one another, allowing precisely timed responses to
asynchronous external events the system is monitoring or controlling.

System Reference Clock

The PXI-1000 supplies the PXI 10 MHz system clock signal (PXI_CLK10)
independently to each peripheral slot. An independent buffer (having a
source impedance matched to the backplane and a skew of less than 1 ns
between slots) drives the clock signal to each peripheral slot. You can use
this common reference clock signal to synch r onize multiple modules in a
measurement or control system. You can drive PXI_CLK10 from an
external source through t he PXI_CLK10_IN pin on the P2 connecto r of the
Star Trigger Slot. (See Table B-1, P1 (J1) Connector Pinout for the System

Controller Slot, in Appendix B, Pinouts.) Sourcing an external clock on

this pin automatically disables the backplane’s 10 MHz source.
