WebI/Q data can be generated at a relatively slow rate (e.g. millions of bits per second), perhaps generated by software in part of the physical layer of a protocol stack. I/Q data … WebLO or Carrier feed-through, sometimes called Origin Offset, can be caused by: • The two mixers not being identically matched and balanced, resulting in LO leakage which is dependent on carrier frequency. • DC offset at the I and/or Q inputs, resulting in LO leakage which is independent of carrier frequency. in and out uciWebBasic work offsets are very simple to specify: simply enter one of G54, G55, G56, G57, G58, or G59. Most machine startup with G54 selected. It’s a good practice to put a G54 into the safety line at the top of all of your g-code programs to make sure you know what work offset is being used unless you have reason to want to leave that aside. inbouw trampoline
