Standard dimension ratio (SDR) is a method of rating a pipe's durability against pressure. The standard dimension ratio describes the correlation between the pipe dimension and the thickness of the pipe wall. [1] Common nominations are SDR11, SDR17, SDR26 and SDR35. Pipes with a lower SDR can withstand higher pressures.
A 1951 USAF resolution test chart is a microscopic optical resolution test device originally defined by the U.S. Air Force MIL-STD-150A standard of 1951. The design provides numerous small target shapes exhibiting a stepped assortment of precise spatial frequency specimens.

The introduction of the Camera Link Interface Standard (1.0) was released in October 2000. Revision 1.1 was adopted in January 2004, with expanded software function support. The standard committee adopted version 1.2 in January 2007, introducing mini SDR ("Shrunk D Ribbon") connectors (SDR-26) and power over Camera Link (POCL).
The interface dimensions for SMA connectors are listed in MIL-STD-348. [5] The SMA connector employs a 1 ⁄ 4 inch diameter, 36-thread-per-inch threaded barrel. The male is equipped with a hex nut measuring 5 ⁄ 16 inch (0.3125 inch / 7.9 mm) across opposite flats, thus taking the same wrench as a #6 SAE hex nut.

AN/SQS-26 was a United States Navy surface ship, bow mounted, low frequency, active/passive sonar developed by the Naval Underwater Sound Laboratory [1] and built by General Electric and the EDO Corporation.
[12] [13] PQ is not backward compatible with the BT.1886 EOTF (i.e. the gamma curve of SDR), while HLG is compatible. Chart showing the PQ electro-optical transfer function. PQ is a non-linear transfer function based on the human visual perception of banding and is able to produce no visible banding in 12 bits. [14]
