12.6 Output Protection
The output protection consists of over-voltage protection (OVP) and over-current protection
(OCP). OVP and OCP switches are shared by both outputs. Separate control of OVP or OCP
for both channels is not supported.
12.7 Single-ended/Differential Settings
The unit offers two output modes, single-ended and differential. They can be set directly in the
"Output Settings" page.
The output terminals on the front panel are "+" on the right and "-" on the left when the output is
differential, and "+" on the left when the output is single-ended.
The analog parameters will differ between the single-ended and differential output modes, as
detailed in the datasheet.
After the output is set to "Differential", a parameter setting box for "Common Mode " will appear
on the carrier settings page, providing an entry for setting the common mode of the differential
signal, as shown below:
Note the distinction between the concepts of "common mode" and "offset". Both are DC levels,
but "common mode " refers to the common-mode component of the differential pair, while "offset"
is the differential mode component.
With "differential" output, the "amplitude" of the signal refers to the peak-to-peak value of the
differential mode signal, i.e.:
( )
pp
pk pk
V V V
+−
−
=−
It is related to the peak-to-peak value of the signal on the "+" or "-" alone by a factor of 2.
