CONTROLS AND TERMINALS
FUSE
The fuseholder, located on the control panel, contains cartridge a
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 the to 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 600-ohm for 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. |
