7 Operational Checks
At the heart of the SE series system is a class D Power Amplifier that operates through a low pass
filter, with RF sourced from a Direct Digital Synthesizer (DDS). The imbedded microprocessor
lends itself nicely to automatic adjustment of system operating parameters. However to ensure
proper operation, verification with calibrated test equipment is required.
7.1 Test Equipment Required
3 1/2 digit digital multi-meter (DMM), calibrated
dual trace oscilloscope, calibrated
frequency counter, calibrated (± 1 Hz accuracy)
250 Watt, 50 Ohm non-reactive dummy load
7.2 Dummy Load Hookup
Connect a 250 Watt, 50 Ohm, non-reactive dummy load to the RF output jack (J50), an N Type
RF connector, on the bottom of the enclosure.
7.3 Power Up
Switch the AC switch (S2) to the ON position.
7.4 Power Up Verification
