R&S NGL200/NGM200
The R&S NGL/NGM outputs the set voltage level on the selected output chan-
nel terminal.
Depending on the mode which the channels are operated in, the followings are
observed:
CR mode
CR mode is a special case of sink mode in which the instrument behaves
like a constant resistor. Only in this mode, the respective channel keys and
display font color in the home window turns cyan.
In "normal" sink mode, the colors are the same as in source mode: green if
the current flowing into the R&S NGL/NGM is below the set current and red
if the current is limited to the set value. The only visible indication of sink
mode is the change of the sign of the current readout change to "Minus".

Also, the operating symbol mode (CV, CC or CR) is displayed at the channel sta-
tus bar of the respective channel.
