"Gen Track" The currently valid and every newly set generator voltage is stored as
the reference value and can then be used for referenced display (by
all channels). If a referenced unit has been selected in the "Unit"
parameter field, the measurement result is referenced to this refer-
ence value and displayed.

Auto Scale
One-off automatic scaling of the bargraph.
"Exec" Clicking this button triggers one-off scaling of the bargraph; the cur-
rent minimum and maximum values are used for the scaling process.
The determined values are entered in the "Left" and "Right" parame-
ter fields below.
For multichannel instruments, the
lowest minimum value and the
highest maximum value of all open combo displays are deter-
mined and entered for all channels in the "Left" and "Right" parameter
fields below.
Spacing
Linear or logarithmic spacing of the bargraph.
"Lin" Linear spacing of the bargraph.
If a logarithmic unit (dB unit) was selected in the "Unit" parameter
field, this field is displayed as not user-accessible and is set to "Lin"
since it makes no sense / is not possible to use a logarithmic bar-
graph to display negative values, or measurement values that have a
logarithmic unit.
"Log" Logarithmic spacing of the bargraph.
This parameter is only available if a linear unit (V, W, etc) has been
selected in the "Unit" parameter field and its value range cannot con-
tain negative numbers.
Example:
Although ∆V is a linear unit, the measurement results can be nega-
tive, which means that logarithmic display is not possible.
