Phase
Measures the phase between two slopes of two channels in the display (Phs). It meas-
ures the relation of the time delay between the sources to the signal period of the mea-
surement source. The instrument searches for the slope of the measurement source
that is closest to the time reference. Then, beginning from this point, it searches for the
nearest slope of the reference source. The time difference and the signal period indi-
cate the measurement result in degrees. Select the "MEAS. SOURCE" and the "REF.
SOURCE".
Burst Width
Measures the duration of burst from the first edge to the last edge (Bst).
Count P+
"Count P+" counts positive pulses in the display. A negative pulse consists of a falling
slope followed by a rising slope. The mean value is calculated from the amplitude of
the measurement signal. A slope is counted if the signal crosses the mean value. A
pulse that passes the mean value only once is not calculated..
Count P–
"Count P–" counts negative pulses in the display. A negative pulse consists of a falling
slope followed by a rising slope. The mean value is calculated from the amplitude of
the measurement signal. A slope is counted if the signal crosses the mean value. A
pulse that passes the mean value only once is not calculated.
Count S+
"Count S+" counts signal changes (slopes) from low level to high level in the display.
The mean value is calculated from the amplitude of the measurement signal. A slope is
counted if the signal crosses the mean value.
Count S-
"Count S-" counts signal changes (slopes) from high level to low level in the display.
The mean value is calculated from the amplitude of the measurement signal. A slope is
counted if the signal crosses the mean value.
Trigger Freq.
"Trigger Freq." measures the frequency of the trigger signal f
Tr
based on the period
duration. The source for the measurement is the current trigger source. The frequency
is determined with a hardware counter with high accuracy of 5 digits.
