In comparison to a desktop, the PXI chassis is similar to the overall enclosure. The&nbsp;<strong>PXI controller<\/strong>&nbsp;is comparable to the CPU or memory, and the PXI\/PXIe peripheral modules are comparable to the PCI\/PCIe version of the same.<\/p>\n\n\n\n<p class=\"has-text-align-left has-text-align-left\">Depending on the model, the PXIe chassis has a combination of four unique slot types: including PXI peripheral, PXIe Timing, PXIe peripheral, and&nbsp;<strong>PXIe Hybrid peripheral.<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"700\" height=\"394\" src=\"https:\/\/www.apexwaves.com\/blog\/wp-content\/uploads\/2022\/05\/pxi-5105-side.jpg\" alt=\"Closeup side view of PXI-5105\" class=\"wp-image-1476\" srcset=\"https:\/\/www.apexwaves.com\/blog\/wp-content\/uploads\/2022\/05\/pxi-5105-side.jpg 700w, https:\/\/www.apexwaves.com\/blog\/wp-content\/uploads\/2022\/05\/pxi-5105-side-300x169.jpg 300w\" sizes=\"auto, (max-width: 700px) 100vw, 700px\" \/><\/figure>\n\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter\"><\/figure>\n<\/div>\n\n\n\n<h2 class=\"wp-block-heading has-text-align-left has-black-color has-text-color\">Which Cards Fit in the Chassis?<\/h2>\n\n\n\n<p class=\"has-text-align-left has-text-align-left\">On certain&nbsp;<strong>PXI Chassis<\/strong>&nbsp;part numbers, there are small symbols located underneath each slot. These symbols are also found on PXI \/ PXIe cards in the upper right corner. This symbol indicates which&nbsp;<strong>PXI \/ PXIe<\/strong>&nbsp;slot the card may be inserted into. It is also important to note that the combination of these symbols (such as the solid circle inside the hollow square example at the bottom of the chart below) indicates that the slot is compatible with both of those card types.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"574\" height=\"304\" src=\"https:\/\/www.apexwaves.com\/blog\/wp-content\/uploads\/2022\/05\/image.png\" alt=\"Chart comparing the symbols and slot types\" class=\"wp-image-3093\" srcset=\"https:\/\/www.apexwaves.com\/blog\/wp-content\/uploads\/2022\/05\/image.png 574w, https:\/\/www.apexwaves.com\/blog\/wp-content\/uploads\/2022\/05\/image-300x159.png 300w\" sizes=\"auto, (max-width: 574px) 100vw, 574px\" \/><\/figure>\n\n\n\n<p class=\"has-text-align-left has-text-align-left\"><strong>PXI Express slots<\/strong>&nbsp;can be used for both PXI cards and system timing cards.&nbsp;<strong>PXI Express System Timing<\/strong>&nbsp;cards, however, require a connector on the bottom of the card- which mean that only PXI Express cards can be used.<\/p>\n\n\n\n<p class=\"has-text-align-left has-text-align-left\">You can insert PXI cards in PXI peripheral slots and they will accept PXI cards with standard connection types. The hybrid or mixed backplane connections of a PXI Express Hybrid slot accepts both the PXI Express card and the&nbsp;<strong>32-bit CompactPCI card<\/strong>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading has-text-align-left has-black-color has-text-color has-link-color wp-elements-ead0dc3b8261c7155ad01999b3c35e38\" style=\"font-size:25px\">Some PXI \/ PXIe Distinctions<\/h2>\n\n\n\n<p class=\"has-text-align-left has-text-align-left\">A&nbsp;<strong>PXIe<\/strong>&nbsp;and<strong>&nbsp;PXI<\/strong>&nbsp;differ in their mechanic, backplane, and electronic connections. However, they have the same fundamental mechanical principles. Other distinctions include:<\/p>\n\n\n\n<p class=\"has-text-align-left has-text-align-left\"><strong>Timing<\/strong>: With an integrated timing and synchronization capability, a PXI system is great for when you need to address advanced timing and synchronization needs. The PXI chassis includes a dedicated local bus, trigger bus, and&nbsp;<strong>10 MHZ input clock<\/strong>. On the other hand, a PXI Express chassis includes a 100 MHz differential system clock and differential signaling.<\/p>\n\n\n\n<p class=\"has-text-align-left\"><strong>Cooling<\/strong>: Chassis from NI are developed and tested to meet or exceed the cooling needs of the most power-hungry PXI modules. According to the PXIe power specification, each peripheral slot must have a minimum of&nbsp;<strong>30 W<\/strong>&nbsp;of power and be able to dissipate the equivalent amount of heat. The PXIe Chassis has an advanced cooling system, with the ability to deliver at least&nbsp;<strong>38.25 W<\/strong>&nbsp;of power and cooling to each peripheral slot, with certain chassis able to provide&nbsp;<strong>58 W or 82 W<\/strong>&nbsp;of cooling to a single slot.<\/p>\n\n\n\n<h3 class=\"wp-block-heading has-text-align-left has-black-color has-text-color has-link-color wp-elements-6f3c25702460cd563ce71daf5d7da859\" style=\"font-size:25px\">PURCHASING THE CORRECT PARTS<\/h3>\n\n\n\n<p class=\"has-text-align-left\">When you purchase a part with&nbsp;<a href=\"https:\/\/www.apexwaves.com\/\">Apex Waves<\/a>, we provide all available part manuals and documentation to view and download as PDFs.
