3-10 Operation
DS360 Ultra Low Distortion Function Generator
The output impedance changes for unbalanced and balanced. Each output (positive and
negative) has the selected source impedance for unbalanced outputs. For balanced
outputs, each output has 1/2 the selected source impedance.
Source Impedance for + or - Output
Source Impedance Unbalanced Balanced
50Ω 50Ω 25Ω
150Ω
75Ω
600Ω 600Ω 300Ω
Hi-Z
25Ω 25Ω
The selected source impedance is displayed under the IMPEDANCE heading to the left
of the display. To change the impedance, press [SHIFT][impedance], where impedance
is either 50Ω, 150Ω, 600Ω or Hi-Z. It is not necessary to press an entry key to select
source impedance’s.
If changing the source impedance from Hi-Z or 600Ω to 50Ω or 150Ω would cause an
out of range amplitude or offset, the following will occur. The DS360 will beep, display
the message Adj volt and adjust the amplitude to 14.4V
PP
and the offset to 0 V
