GENERAL
INFORMATION
1-1. DESCRIPTION.
1-2.
The solid state 467A Power Amplifier/Supply
is a 10 watt peak power amplifier and -20 to +20 voit
de power
supply.
The power
amplifier has a wide
bandwidth with low de drift from de to 1 MHz offering
wide applications
wherever
a power
source
is ге-
quired.
Low distortion (<0, 01%), low drift and 0. 3%
gain accuracy are obtained with high quality compo-
nents and multiple feedback techniques.
The gain of
the amplifier
may
be varied between
one and ten by
a front panel
switch which provides fixed gain steps
accurate to +0. 3%. A variable gain control enables
the user
to set the gain anywhere between zero and
ten witha resolution of better than 0.1% of full output.
Table 1-1 gives the specifications for the 467A Power
Amplifier /Supply.
1-3. OUTPUT
CAPABILITY.
1-4.
An output greater
than
20 volts peak and 0.5
ampere peak is available from ас up to 1 MHz.
The
amplifier is protected at all times from short cir-
cults.
The input circuit of the 467A is protected
against
damage
from
voltages
up to 200 volts р-р.
Input and output connectors are provided at the front
and rear of the instrument.
The amplifier is a three
terminal
device
isolated
from
chassis
and may
be
floated up to 200 volts de above chassis ground.
1-5.
POWER
SUPPLY.
1-6.
A front panel switch converts the amplifier to
a power supply that delivers +20 volts de at currents
ир to +0. 5 ampere.
The output level is controlled
by a potentiometer which permits voltages to be set
with resolution of 0.1% of full scale.
Full scale
ranges of +1,+2,44, +10, and+20 volts are selected
by the front panel range switch.
