Measure
Push the Measure button to access automatic measurements. There are 34 types
of measurements available. You can display up to six at a time. The oscilloscope
displays the measurements towards the bottom of the screen after you choose
them.
Key points
Taking Measurements. You can display up to six automatic measurements at a
time. The waveform channel must be on (displayed) to make a measurement.
Automated measurements cannot be taken on reference waveforms, or while
using XY or scan mode. The measurements update about two times per second.
The following tables list each automatic measurement by category: time or
amplitude.
Table 1: Time measurements
Measurement Description
Period The time required to complete the first cycle in a
waveform or gated region. Period is the
reciprocal of frequency and is measured in
seconds.
Frequency The first cycle in a waveform or gated region.
Frequency is the reciprocal of the period; it is
measured in hertz (Hz) where one Hz is one
cycle per second.
DelayRR (rising to
rising)
The time between the mid reference (default
50%) amplitude point of two different rising
waveforms. See also Phase.
DelayFF (falling to
falling)
The time between the mid reference (default
50%) amplitude point of the two different falling
waveforms.
DelayRF (rising to
falling)
The time between the mid reference (default
50%) amplitude point of the rising and the falling
waveforms.
DelayFR (falling to
rising
The time between the mid reference (default
50%) amplitude point of the falling and the rising
waveforms.
Rise Time The time required for the leading edge of the
first pulse in the waveform or gated region to
rise from the low reference value (default = 10%)
to the high reference value (default = 90%) of
the final value.
Fall Time The time required for the falling edge of the first
pulse in the waveform or gated region to fall
from the high reference value (default = 90%) to
the low reference value (default = 10%) of the
final value.
