CONTROLS AND TERMINALS
FUSE
The fuseholder, located on the control panel, contains a cartridge
fuse of the Slo-Blo type. For 115-volt operation, a 1.6-ampere
fuse is used, and for 230-volt operation, an.
8
-ampere fuse of the
same type
is
used. Characteristics of the Slo-Blo fuse used in the
Model 206A are given in the Table of Replaceable Parts.
POWER
This rotary switch controls the power supplied to the instrument
from the power
lim
Illumination of the tuning
dial
window pro-
vides indication that the power switch is turned on.
IMPEDANCE
The setting of this four -position rotary switch indicates
the im-
pedance at the output binding posts. In three positions (50,
150,
and 600) the switch connects windings of the impedance -matching
transformer to the OUTPUT binding posts for balanced
50-ohm,
150-ohm, or 600-ohm operation.
In
the fourth position, 600G, the
switch bypasses the impedance -matching transformer and arranges
the output circuit for 600-ohm unbalanced operation.
CT OUTPUT
G
The Model 206A binding posts will accept either a banana plug or
wire. The terminals are so arranged that any double banana plug
with
314 inch spacing may be used to connect to any pair of adja-
cent terminals.
