Model 467A
1-1. DES CRIPTION.
1-2. The solid state 467A Power Amplifier / Supply
is a 10 watt peak power amplifier and -20 to +20 volt
dc power supply. The power amplifier has a wide
bandwidth with low dc drift from dc to 1 MHz offering
wide applications wherever a power source is re­
quired. Low distortion «
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
3 % . A variable gain control enables

the user to set the gain anywhere between zero and
ten with a resolution of better than

Amplifier / Supply.

1-3. OUTPUT CAPABILITY.

An
1-4. output greater than
ampere peak is available from dc up to 1 MHz. The
amplifier is protected at all times from short cir­
cuits. The input circuit of the 467A is protected
against damage from voltages up to 200 volts p-p.

INFORMATION
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 dc above chassis ground.

1-5. POWER SUPPLY.

1-6. A front panel switch converts the amplifier to
a power supply that delivers ±20 volts dc at currents
up 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, ±4, ±10, and ±20 volts are selected
by the front panel range switch.
