Output and Channel Controls
Only applicable for R&S NGL202, these keys control the channel output settings of the
instrument.

Power Derating
The NGL202 includes two identical channels with a continuous voltage range of 0 V to
20 V. The instrument provides a source of up to 6 A for voltage below 6 V and 3 A for
voltage range from 6 V to 20 V.
Similar to NGL202, the NGL201 provides a single channel wiith an output power of up
to 60 W.
Combination of the set voltage and current limit results in the following output perform-
ance graph.

Output Modes
The R&S
NGL200 includes three operating modes, i.e. the constant voltage (CV), con-
stant current (CC) and constant resistance (CR). The instrument switches automati-
cally between CV and CC depending on the connected load. In CR mode, the instru-
ment is not switched automatically into sink more. Instead, the instrument operates in
the CR mode (
) as soon as it switches from soure mode to sink mode.
CV mode
shows that in the range of voltage regulation, the output voltage V
out
remains constant while the current may increase to its maximum value I
max
when the
connected load is increasing. In CV mode, the font text in the channel display area
changes to green.
