3.9 Phase Measurements

Phase 1 to 2 measures the phase difference between signals on channel
1 and channel 2, and the phase difference is shown in degree. Moreover,
auto triggering is enabled by default for time interval measurement, and
the trigger levels are set to the 50% points of each signal. One may
manually disable auto triggering and change the trigger levels and slopes
settings (refer to Ch.4.8).

The Channel 2 here acts as the reference. One period on Channel 2 will
be defined 360˚. As the Channel 1 leads the Channel 2, the pulse result
will be positive.

To make phase measurement
1. Connect your signal sources to channel 1 and channel 2 respectively.
2. Press OTHER MEAS button.
3. Press the softkey under (PHAS 1 to 2) to select phase measurement

function.

4. Optional settings:

a. Use softkey “Phase 1 to 2” and GATE&ExtArm button to set the auto

or external ARM if it’s needed (refer to Ch.4.3).

b. Use Scale&Offset button to set the scaling and offset parameters if

it’s needed (refer to Ch.4.4).

c. Use Limit Modes button to set the OnFail, OUT*, Upper and Lower

limits if it’s needed (refer to Ch.4.5).

d. Use Stats button to set up the statistics function and limit filtering if

it’s needed (refer to Ch.4.6).

e. Use the selections in the CH1 & CH2 to set the input conditions and
