Aramid packing is made of braids of aramid fiber, a strong organic substance, which are impregnated with PTFE dispersion and lubricant. This material is suitable for use as dynamic sealing in medias that contain solid particles. Its working temperature: -100 to 260oC.
An Arbitrary Waveform Generator (AWG) is a piece of electronic test equipment used to generate electrical waveforms. These waveforms can be either repetitive or single-shot (once only) in which case some kind of triggering source is required (internal or external). The resulting waveforms can be injected into a device under test and analyzed as they progress through the device, confirming the proper operation of the device or pinpointing a fault in the device. AWGs can generate any arbitrarily defined waveshape as their output. The waveform is usually defined as a series of waypoints (specific voltage targets occurring at specific times along the waveform) and the AWG can either jump to those levels or use any of several methods to interpolate between those levels.
