Bandwidth Switching Accuracy
Several IF filters are used to obtain an optimal resolution (in signal spectrum analysis) according to the scan
width. When switching from one IF filter to another while measuring one and the same signal, an error is
generated for the difference in loss. This error is defined as the bandwidth switching accuracy.
