Model 467A
GENERAL.
3-1.
3-2. The Model 467A Power Amplifier/Supply can be
operated as a power amplifier or a power supply.
Controls on the front panel provide:
either operating mode and (2) selection of fixed or
variable amplifier gain and power supply ranges.
3-3. DESCRIPTION
3-4. Figure 3- 1 gives the description and function
of the 467A controls, indicators and connectors.
3-5. OPERATING
3-6. When operated as a power amplifier (non-invert­
ing), the Model 467A has four calibrated gain factors
(AMPLIFIER: Xl, X2, X5, and X10) and provides a
maximum output power of 10 watts peak for input fre­
quencies between dc and 1 MHz. Accuracy of ±0.3%
from dc to 10 kHz is obtained when operating into a
load of 40 ohms or greater.
lated), the instrument can be operated in five ranges
of plus or minus output voltages (SUPPLY:
±4, ±10, and ±20). The amplifier gain, or the ± dc
output can be varied with the VAR. GAIN/VOLTS ADJ.
control. The input and output ter minals are dc isolated
from earth ground. Connection of a grounding strap
between the power line ground
references both the INPUT and OUTPUT (� terminals
to earth ground.
