Measure Commands - Rigol DS1000Z Series Programming Manual

Chapter 2 Command System

:MEASure Commands

DS1000Z supports the auto measurement of the following 24 waveform parameters and provide the
statistic function for the measurement results. In additional, you can use the frequency counter to make
more precise frequency measurement. The :MEASure commands are used to set and query the
measurement parameters.

DS1000Z Programming Guide
Defined as the time between the threshold middle points of two consecutive,
like-polarity edges.
Defined as the reciprocal of period.
The time for the signal amplitude to rise from the lower limit to the upper limit of
the threshod.
The time for the signal amplitude to fall from the upper limit to the lower limit of the
threshod.
The time difference between the threshold middle points of a rising edge to the
next falling edge of the pulse.
The time difference between the threshold middle points of a falling edge to the
next rising edge of the pulse.
The ratio of the positive pulse width to the period.
The ratio of the negative pulse width to the period.

The time difference between the rising edges of source 1 and source 2. Negative
delay indicates that the selected rising edge of source 1 occurred after the selected
rising edge of source 2.
The time difference between the falling edges of source 1 and source 2. Negative
delay indicates that the selected falling edge of source 1 occurred after the selected
falling edge of source 2.
Phase difference calculated according to "Delay 1→2 " and the period of source
1, expressed in degree. The calculation formula is as shown below.
