Displaying Channel Pairs
A channel pair is a reference channel and a response channel used to display a dual channel function, such
as an FRF.
In the Input channel configuration panel, set at least one channel as a reference channel. After you click OK
and look at the channel buttons in the main window, you will notice that each reference channel now has a
bold number. One of them also is underlined. That channel will be used as the reference channel for any
dual function displays.
To change to another reference channel, right click on the channel of interest. It will now be underlined.
All channels are response channels, even those that have been designated as
reference channels.
Changing the Display Range
To change the maximum or minimum range value: Left-click on upper or lower scale value that is to be
changed, then enter the new value. An example follows.
To change the X-Axis: Hold down the key, at the same time, left-click and drag the mouse cursor
horizontally on the plot. Two vertical cursor lines will define the new x-axis end points.
In this example, the cursor and PC
keyboard were used to change the
maximum scale value from 3.000
volts to 3.800 volts.
