Range
Sets the instrument to the desired range.
Trigger %
The trigger level in percent of full scale. If the level is set to 10% and the range is set to
200uJ, then the instrument will trigger at signals greater than 20uJ.
The QUAD-4TRACK examines all 4 channels for a trigger event in sequences, so if any
of the 4 channels are above the set trigger level, all 4 channels will be measured.
Show Boundary
When this control is ON a circle with the set diameter is plotted on the X Y graph. When
coupled with the plot history, this can be used for limit testing.
Boundary Diameter
The diameter of the Boundary Circle plotted on the X Y graph. When coupled with the
plot history, this can be used for limit testing.
Average Data
When turned on the data is averaged using a moving average, also known as a Box Car
filter.
This means that the average will not be complete until all the samples are taken, but the
displays will reflect the current averaged value until this happens. Suppose that a batch
size of 5 is selected, and then Average Data is selected. The samples will be averaged as
follows:
Sample Number
Number Averaged
1 1 sample summed, divided by 1
2 2 samples summed, divided by 2
3 3 samples summed, divided by 3
4 4 samples summed, divided by 4
5 5 samples summed, divided by 5
