ANALOG INPUT JACKS: These jacks accept four standard 1/4-inch
d
iameter phone plugs with
the analog input signal connected to TIP, signal ground to RING, and shield to SLEE VE. Full scale
v
oltages of ±1
to ±10 can be accommodated on each
c
hannel, independent of the other c
hannel ranges . Coarse ranges are
selected by jumpers inside the 59313Α and fine input adjustments are
m
ade with
t
he front panel GAIN controls .

REVERSE CHANNEL JACK : Connects the instrument to be driven by the reverse channel . The
R
VS CHAN jack accepts α standard 1/8-inch diameter mini phone plug with
s
ignal connected to TIP and ground
connected to SLEEVE. The channel is α programmable ΝΡΝ transistor switch closure to ground, requiring an
external supply .
W hen OFF,

i
t is grounded and can sink up to 200 mA.
