Avoid damaging the carton and packing material during equipment unpacking. Use the following steps for unpacking the 3500 / 3500A. ● Cut and remove the sealing tape on the carton top and open the carton. ● Grasp the 3500 / 3500A transit case firmly, while restraining the shipping carton, and lift the equipment and packing material vertically and place the 3500 / 3500A transit case and end cap packing on a suitable flat, clean and dry surface. ● Remove the protective plastic bag from the 3500 / 3500A transit case. Place protective plastic bag and end cap packing material inside shipping carton. Store the shipping carton for future use should the 3500 /3500A need to be returned. Checking Unpacked Equipment ● Inspect the equipment for damage incurred during shipment. If the equipment has been damaged, report the damage to Aeroflex. ● Check the equipment against the packing slip to see if the shipment is complete. Report all discrepancies to Aeroflex.

PRINCIPLES OF OPERATION The 3500 contains the following assemblies: LCD T/R KEYPAD RF DIGITIZER POWER SUPPLY BATTERY MULTI- FUNCTION RF SWR ANT REMOTE DC IN AUDIO The Power Supply PCB Assy is responsible for supplying power to the internal modules for operation and for charging the internal batteries. The RF Digitizer PCB Assy converts the baseband signal to a modulated 10.5 MHz Tx IF which is upconverted in the RF Assy to provide an RF Generator output. The Receive signals are down-converted to 13 MHz and demodulated to baseband signals. The Multi-Function PCB Assy includes the processors, FPGA and memory to send data from the RF Digitizer PCB Assy through the Power PC to the ColdFire for display on the LCD Display. Keyboard inputs are processed to provide instructions to the RF Assy. The RF Assy consists of the RF Controller PCB Assy and the RF Converter PCB Assy. The RF Converter PCB Assy converts the 10.5 MHz TX IF to the 2 MHz to 1 GHz RF and from the 2 MHz to 1 GHz receiver input to the 13 MHz RX IF. The RF Converter PCB Assy also contains the VSWR coupler and associated circuitry and the Power Termination. The RF Controller PCB Assy provides the TCXO, LOs and digital circuitry necessary for software control and for tuning and level control.
