"Vertical" Sets two vertical cursor lines and measures the time from the trigger
point to each cursor line, the time between the cursor lines and the
frequency calculated from that time.
Results: t1, t2,

"Vertical &
Horiz." Combines the "Horizontal" cursor and "Vertical" cursor measure-
ments. Two horizontal and two vertical cursor lines are set. The vol-
tages and times are measured at the cursor positions, as well as the
delta of the voltage and time values.
Results: t1, t2,

"V-Marker" Sets two vertical cursors and measures the values of the waveform at
the crossing points of the cursor lines and the waveform. Also, the dif-
ferences of the two values in x- and y-direction are displayed.

Source
Defines the source of the cursor measurement as one of the active waveforms.
You can use cursors on analog input signals, math waveform, reference waveforms,
XY-diagram, and FFT waveform.
If option R&S RTA- B1 is installed, you can use the vertical cursor to measure individ-
ual logic channels, and the V-Marker to measure pods.
Remote command:
CURSor<m>:SOURce

Second Source
Enables and selects a second source for the cursor measurements. If enabled, the
second cursor measures on the second source. Using a second source, you can mea-
sure differences between two waveforms with cursors. Both sources must be in the
same domain (time domain or frequency domain). In FFT, for example, you can mea-
sure the difference between min hold and max hold waveforms.
