High Speed Power Meter

These can be stopped at any time by clicking Stop. If the timer is set,
power measurements will stop automatically after the specified
duration.

Note: The remaining duration is indicated under the Start and Stop button.

The Reset button will reinitialize the Min./Max. acquisition results in the
data display.

The results of the Min./Max. function are continuously updated in the
matching lists. When a logarithmic scale is used, the Max.−Min.
calculation is made to continuously provides the difference between the
two extremes. In a linear scale, the Min./Max. ratio is computed to provide
valuable information.

If the power reaches the saturation level, +++++++ will be
recorded as the Max. value. The Max.-Min. or Min./Max. calculation will
also be +++++++.

If the detected power decreases below the lowest measurable power,
the Min. value will be – – – – – – – and both Max.-Min. or Min./Max. will
display – – – – – – –.

If a Min./Max. calculation is made with a null Min. value, ! ! ! ! ! ! ! will
be displayed.

If a channel is shown in the data display but is not part of the selected
channels for a Min./Max. acquisition, * * * * * * * will be displayed to
indicate that no power reading is being performed at that time.

Selecting Autorange for this channel will prevent these symbols from
appearing.
