I need to calibrate a sliding load. In order to verify its return loss would I simply have to measure it by moving the slide to each position for each test frequency then average the six return loss values?

- Dr_joel Jan 23, 2009 8:22 AMTo really measure a sliding load, you would need to meaure the relfection at each slide point, then compute the differences (worst case) to come up with the min-max vswr of the load. The difference is the quality of the load, since it should provide exactly the same gamma at each slide point. The only reason it won't is if the transmission line (airline) is not 50 ohms. The actual value of the return loss does not substantially contribute to the error of a sliding load.
