Source / Source 2
Defines the waveform to be measured. For delay, phase, and power measurements, 2
sources are required.
The sources can be any active input signal, math or reference waveform. Available
source waveforms depend on the measurement type, see Chapter 3.2.2, "Measure-
ment Types", on page 74.
Remote command:
MEASurement<m>:SOURce on page 188
All off
Disables all active measurements.
Remote command:
MEASurement<m>:AOFF on page 189
Slope
Sets the slope for the delay measurement type.
"Positive"
Delay between the first rising edge of each source waveform.
"Negative"
Delay between the first falling edge of each source waveform.
"Either"
Delay between the first edge of each source waveform, no matter if it
is rising or falling.
Remote command:
MEASurement<m>:DELay:SLOPe on page 190
3.3 Cursor Measurements
The cursor measurement determines the results at the current cursor positions, or
between the cursor lines. The cursors can be positioned manually at fixed positions, or
they can follow the waveform.
You can perform cursor measurements on analog input signals, math waveform, XY-
diagram, as well as on logic channels and buses (requires option R&S RTH-B1).
► To configure the cursor measurement, long-press the CURSOR key.
► To start and stop the last configured measurement, press the CURSOR key.
3.3.1 Cursor Types and Results
The results of cursor measurements are displayed at the top of the display.
4 cursor types are available.
Vertical cursors
For vertical cursors, two results are displayed by default: the absolute value of the time
difference between the cursor lines Δt and its inverse value 1/Δt. Optionally, the posi-
