are fed from the outputs of the oscillator and ramp generator. The output of the
bridge is then fed through the low pass filter network to recover the signal
waveform; then fed to the N connector at the output.
There is a current limit protection circuit to protect the unit, in addition to the input
drive clamp. Current and voltage samples are taken from the output and fed to
the BNC connectors on the front panel for monitoring purposes.
The AC supply is fed through an EMI filter to two power supplies that convert the
AC to 90 Vdc for the amplifier. one DC supply is used for 45 Volt required for the
cooling fan and additional DC-DC converters to supply the fl 15 V for the
gate drivers and +/- 15 volt rails, for the control circuitry.
