The HSA user guide says that using a log-frequency scale is useful for filter analysis: "When measuring filter characteristics, it is useful to look at the stimulus response over a wide frequency range. Setting the analyzer x- axis (frequency) to display logarithmically provides this function. The following example uses the tracking generator to measure the stop band attenuation of a 370 MHz low pass filter."
Yet, this example does not show how to set log frequency, and a search of the guide yields nothing about setting a log frequency scale. What am I missing?
