Test Procedure
Initial Test Set Up
The PI2007-EVAL1 is designed with two bias circuit
options, bias resistor R
PG
(R1 and R2) and a constant
current circuit. The constant current biasing circuits
are installed; where R1 and R2 are not installed.
Leave the enable inputs (EN1 and EN2) disconnected
(open).
