Advanced Configuration
The 8302 amplifier was designed to offer excep
-
tional versatility in operation. You can choose from
a range of field-configurable options, including:
•
Enable the unbalanced or balanced signal input
connections, or use both inputs.
•
Select DC-coupled or AC-coupled operation.
•
Enable DC Servo to ensure DC offset remains
at zero and safely drive coils and transformers.
•
Select Controlled-Current or Controlled-Voltage
modes of operation.
•
Select between two compensation networks for
Controlled Current operation: CC1, designed
for loads from 50 µH to 500 µH; or CC2, de
-
signed for loads from 500 µH to 1.5 mH.
•
Limit current output via programmable current
limits.
•
Adjust the amplifier gain from 0.16 to 40 in
increments of 0.16.
•
Configure two 8302 amplifiers for operation as
a Push/Pull (series) or Parallel system.
•
Enable electronic gain matching to optimize
parallel operation of two 8302 amplifiers.
•
Select and enable a synthetic impedance from
0.125 ohms to 0.875 ohms.
