The :MEASure:FREQuency command installs a screen measurement and starts a frequency measurement. If the optional source parameter is specified, the current source is modified. If the edge on the screen closest to the trigger reference is rising, then frequency = 1/(time at trailing rising edge - time at leading rising edge). Else, frequency = 1/(time at trailing falling edge - time at leading falling edge).
