In Manual mode, you can use the numeric keys to set the step size.
Signal Track
Enables or disables the signal tracking function. This function is used to track and
measure the signal whose frequency is unstable and whose transient variation in
amplitude is less than 3 dB. Place Marker1 (refer to descriptions in "Marker
Measurement") onto the signal under test to track and measure the variation of the
signal. The signal tracking process is shown in the following figure:
