In the dual modes X2, Y2, MAG2 and PHA2 variables can also be selected.
Use the up/down buttons to select the required variable settings.
The values C1 and C2 within each equation are user-defined integer constants and
are adjusted by typing the required value into the text entry boxes and pressing
<return>.
The equations are calculated using 64-bit integers to maintain full accuracy through
to the 32-bit result that can be shown on the digital indicators. Care should be taken
when defining the equations so as to make the best use of the available output range.
If the equation outputs are set to appear at any of the analog output connectors on the
rear panel using the Configuration menu, then the output range should be adjusted to
lie in the range -10000 to +10000. Values outside this range will result in these
analog outputs limiting at ±10.000 V, although the digital value will still appear
correctly on the screen.
Note that the equations continue to be calculated even when the Equations panel is
not displayed, if they are selected for output to the analog output connectors.
Otherwise they are calculated when requested by computer command.
