Time Measurements panel
Use the T
ime Measurements panel to add timing-related measurements to the Results bar. Time measurements can be taken on
time-domain analog, math, and reference waveforms. Timing measurements can also be taken on some digital channel signals.
To open the Time Measurements panel:
1. Tap Measure button.
2. Tap the Time Measurements panel.
To add a measurement to the Results bar:
1. Select the signal source.
2. Select a measurement. If a measurement requires two signal sources, select the sources in the Source 1 and Source 2 fields.
3. Tap Add. You can also double-tap a measurement to add it immediately to the Results bar.

Measurement Description
Burst Width The duration of a series of adjacent crossings of the Mid reference level. Bursts are separated by a
specified idle time.
The measurement is taken on each burst in a waveform record.
Data Rate Data Rate is the reciprocal of Unit Interval.
The measurement is taken on each bit of the waveform record.
Delay The time difference between the mid reference (default 50%) amplitude point of two different
waveforms. Y
ou can specify the signal edges to measure in the measurement’s Configuration menu.
The measurement requires two sources.
Duration N-Periods The time required to complete N cycles. A cycle is the time between two adjacent (same direction)
crossings of the mid reference level.
The measurement is taken on each cycle in the waveform record.
Fall Time The time required for the trailing edge of the first pulse in the measurement region to fall from the high
reference value (default = 90%) to the low reference value (default = 10%).
The measurement is taken on each cycle of the waveform record.
Falling Slew Rate The rate of change (in volts/second) as an edge transitions from a high reference level to a low
reference level.
The measurement is taken on each cycle of the record in the measurement region.
Frequency The frequency of the waveform. Frequency is the reciprocal of Period (Frequency = 1/Period).
High Time The time the signal remains above the Top reference level.
The measurement is taken on each cycle in the waveform record.
Hold Time The time between the specified Mid reference level crossing on the clock signal to the closest Mid
reference level crossing on the specified data signal.
The measurement is taken on each specified clock edge in the waveform record.
