Power Derating
The NGL202, NGM202 models include two identical channels with a continuous volt-
age range of 0 V to 20.05 V. The instrument provides a source of up to 6.01 A for volt-
age below 6 V and 3.01 A for voltage range from 6 V to 20 V.
Similar to NGL202, NGM202, the NGL201, NGM201 models provide a single channel
with an output power of up to 60 W.
Combination of the set voltage and current limit results in the following output perfor-
mance graph.

Operation Modes
The R&S
NGL/NGM operates in three modes, i.e. the constant voltage (CV), constant
current (CC) and constant resistance (CR). The instrument switches automatically
