Pulse Characteristics to measure various pulse
characteristics.
The following lists shows the measurement items (Measure menu) for
pulse characteristics and their definitions (see Figure 3--45).
H
Pulse Width. Measures the time from rising edge to falling edge at the level
of --3 dB (50%) of the mean power for the pulse-on.
H
Peak Power.
Measures the maximum power during the pulse-on.
H
On/Off Ratio.
Measures the ratio of the mean power during the pulse-on to
that during the pulse-off time.
H
Pulse Ripple. Measures the difference between the maximum and the
minimum power during the pulse-on.
H
Repetition Interval. Measures the time from a pulse rising edge to the next
pulse rising edge.
H
Duty Cycle.
Measures the ratio of the pulse width to the repetition interval.
H
Pulse-Pulse Phase. Measures the phase difference between the first pulse
and the selected pulse in the analysis window.
H
Channel Power.
Measures the channel power for the pulse-on spectrum.
H
OBW.
Measures the OBW (Occupied Bandwidth) for the pulse-on spectrum.
H
EBW. Measures the EBW (Emission Bandwidth) for the pulse-on spectrum.
H
Frequency Deviation. Measures the signal frequency change from the
center frequency over time during the pulse-on.
For information about Channel Power, OBW and EBW measurements, refer to
the S/A (Spectrum Analysis) mode.
Channel Power page 3--5
OBW page 3--11
EBW page 3--14
The frequency deviation measurement is based on the Frequency versus Time
measurement in the Transient mode. Refer to page 3--45.
