1

ADC loop back (incoming analog signal is amplified, digitized, down-sampled,

LOOPED, up-sampled, converted to analog, amplified/filtered) (G) to (B) loop.

2

Local analog loop back (digital signal is up-sampled, converted to analog,

amplified/filtered, LOOPED, amplified, digitized, down-sampled, sent back) (E)

to (J) loop.

3

DAC loop back (digital signal is up-sampled, converted to analog, LOOPED

digitized, down-sampled, sent back) (E) to (J) loop. Same as mode 2.

4

Remote analog loop back (incoming analog signal is amplified, LOOPED,

amplified/filtered, sent back) (J) to (D) loop.

7

Digital loop back: signal is captured from the AC-link and sent back as is. Slot
