Slot Width

Slot width is the width of each slot in milliseconds. All slots in a single frame should have exactly the same

width.

Start and End Exclusion

Start exclusion is the time in milliseconds to be excluded from the beginning of each slot for power calculation.

End exclusion is the time in milliseconds to be excluded at the end of each slot for power calculation. This

feature is generally used to define spacing between slots, although it may not be evident from the Time Slot

mode graph. the following are general guidelines for Time Slot mode settings:

• The exclusions should not eclipse the entire slot width:

Start Exclusion + End exclusion < Slot width

• The maximum capture time is limited by the sensor:

Slot width x Number of slots = Total capture time

Apply Above Settings Button

The Apply above settings button applies all changes made to the “Time Slot Mode” settings. Changes to these

settings do not take effect until clicking this button.

3-6 Scope Mode

Scope mode is only available with power sensor models MA24108A, MA24118A, and MA24126A. In Scope

mode, the sensor acts similarly to an oscilloscope in that it can be used to measure power as a function of time.

There are two parameters needed to define the scope mode operation: the capture time and the number of data

points. Operation in scope mode proceeds as follows: sensor first waits for a trigger. Upon receiving a trigger,

the sensor starts collecting data at its sample rate for the duration of the capture time. This will typically

result in a number of samples that exceed the number of displayed data points. In this case, individual samples

are averaged together to display the requested number of data points. The descriptions of the Scope mode

settings are given below:

Capture Time

The Capture Time represents the time displayed on the screen at any one time. If a positive delay is specified

for the trigger delay item, the capture time will commence once the specified delay has been reached.
