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?

Hello wreeve,
Thank you for pointing this out - it is an error in the user guide. You can safely ignore that sentence "Setting the analyzer x-axis (frequency) to display logarithmically provides this function." This instrument does not support logarithmic scale on the x-axis, only the y-axis.
Apologies for the confusion.
