RMS, Mean, σ
This measurement type provides two cursors and measures the effective value (RMS –
root mean square), the mean value and the standard deviation within the interval set
by both cursors.
Duty Ratio
"Duty Ratio" provides three cursors to determine the duty ratio between the two hori-
zontal cursors. The third cursor specifies the threshold at which the duty ratio is mea-
sured.
Burst Width
"Burst Width" determines the duration of a burst from the first edge to the last edge
(Bst).
Freq. & Period
"Freq. & Period" provides three cursors and measures the frequency and the period.
Rise Time 90%, Rise Time 80%
These measurement types provide two cursors and measure the rise and fall time of
the first rising slope in the display within the time span set by the cursors. The rise time
identifies the time in which the signal rises or falls from 10% to 90% of its amplitude, or
from 20% to 80%.
V-Marker
"V-Marker" provides two cursors and measures three voltages and a time. The values
V1 and V2 correspond to the voltage between the zero base line of the selected curve
and the current position of the first or second cursor. The value ΔV corresponds to the
voltage difference between the two cursors. The value Δt corresponds to the time
between the two cursors.
Crest Factor
The crest factor (peak-to-average ratio) is calculated from the maximum value divided
by the RMS value of the waveform (Crest).
7.3 Automatic Measurements
The R&S
RTC1000 also features various automatic measurements. Up to 6 measure-
ments can run in parallel.
The results of automatic measurements are displayed at the bottom of the screen. The
results of the automatic measurements are also shown in the quick view, they are the 6
results on the right.
