If the measurement result is outside the measurement range and clipping occurs, the
results are marked with < (underflow) or > (overflow). Adjust the vertical scale to get
valid results.

Meas1 = period measurement on C3, no complete period detected
Meas2 = peak to peak measurement on C1, waveform is clipped
Meas3 = pulse count on C3, no pulse detected

3.2.3 Measurement Types
The R&S RTH provides 35 measurement types to measure time, amplitude and power
characteristics, and to count pulses and edges.
All measurement types that require only one source are also available for gated mea-
surements using CURSOR > "Type" = "Measure".
3.2.3.1 Time Measurements
Meas. type Symbol Description Graphic / formula Source
Period T
in s
Time of the first period, measured on the
50% level. The measurement requires at
least one complete period of the signal.

Analog, math,
reference, logic
Frequency f
in Hz
Frequency of the signal, reciprocal value
of the measured first period.

Rise time tR
in s
Rise time of the first rising edge. This is
the time it takes the signal to rise from
the 10% level to the 90% level.

Fall time tF
in s
Fall time of the first falling edge. This is
the time it takes the signal to fall from the
90% level to the 10% level.
