2801/2802 Power Analyzer User Guide
Analog Channel Board
The 2801 is built with one and the 2802 is built with two Analog Channel
Boards fitted. The block diagrams of this circuitry are shown below.
Voltage Input Attenuator Notes
The primary voltage-reducing element formed by the 1 Mohm portion of the
attenuator is comprised of several lesser value resistors in series:
a) To assure the input remains safe when a single resistor fails to a short
circuit;
b) To reduce the voltage coefficient of the attenuator caused by self heating
when high voltages are applied; and
c) To ensure that the input can withstand high voltages in excess of the
maximum specified to the user.
Transducer Input Attenuator Notes
The Transducer input attenuator is similar to the Voltage input attenuator but
with a much lower primary resistance value and a slightly higher output
impedance. Since the input voltages specified are low, only a single primary
attenuator resistor is used as there are no single fault safety issues with this
input.
