SCAN
Indicated by the LED labeled scn. Three
input signals from channels 2, 3 and 4 are
scanned (or selected) by the voltage in chan-

The func a output offers the result of scan-

SAMPLE AND HOLD
Indicated by the LED labeled s&h. This mode
offers two independent channels of full sam-
ple and hold operation. In this mode, channels
2 and 4 are the control channels (as indicat-
ed by the sh trg panel labels), while signals
or voltages in channels 1 and 3 are being
sampled, and the result of this sampling (a
stepped voltage) is available at the func a

The motivation of this setup is that besides
typical processing of external signals, it al-
lows sampling of manually controlled voltag-
es when offsets (either positive or negative) in
channel 1 and 3 are engaged.
