Advanced Amplifiers AA-80M1G-750 Solid State Amplifier

MIL-STD-461G RS103 is used to verify the ability of the EUT and associated cabling to withstand electric fields. MIL-STD-461G RS103 is applicable for equipment and subsystem enclosures and all interconnecting cables. MIL-STD-461G RS103 is applicable as follows:   Frequency Range Applicability 2 MHz to 30 MHz Army, Navy and optional for all others 30 MHz to 18 GHz All 18 GHz to 40 GHz Optional for all   Test Equipment Signal Generator – Creates signals and modulations for the amplifier. Power Amplifier – Takes signal, amplifies it sometimes greater than 1,000,000 times original power (0dbm going into 1000 W). Low Loss Cables – Interconnect all coax equipment after the amplifier. Dual Directional Coupler – Couples off-nominal values of forward and reverse power (typically by 40 dB or 50 dB). Power Sensors – Measures coupled power from dual directional coupler for monitoring (may need attenuator between the forward coupled port and power sensor to avoid damage). Power Meter – Dual channel, displays power sensor reading in dBm or Watts. Tripod – Holds up the radiating antenna, non-metallic. Radiating Antenna – Transducer which emits RF power into space from the signal source. Electric Field Probe – Measures e-field strength (V/m) on X, Y, Z axes, and composite and returns data via fiber cable. Fiber Optic Communication Link – Non-conductive communication link between field probe and probe interface. Probe Interface – Provides both power and communication to the e-field probe.   Procedures The test procedures shall be as follows: a. Turn on the measurement equipment and EUT and allow sufficient time for stabilization. b. Assess the test area for potential RF hazards and take necessary precautionary steps to assure the safety of test personnel.  c.

LV 148 Standards are written for electric and electronic components for vehicles with a 48V Electrical System. This standard details a series of procedures for a test involving electrical normative bases and addressing the practical challenges for vehicle components and systems. LV 148 covers electric and electronic components for vehicles within a 48V electrical system's test conditions. Topics and tests covered include tolerances, operating voltage ranges, and other standard values and specifications. With an increasing amount of completely electric vehicles manufactured every year, the LV 148 will remain relevant in the coming decades to ensure standards. There are two main test setups LV 148 applies for voltage simulations and voltage dropouts. Test setup for voltage simulation DC source Signal generator Auxiliary equipment Measuring devices Test setup for voltage dropouts DC source Electronic switch Signal generator Auxiliary equipment Measuring devices In addition, the LV 148 standards apply to ground offset, short circuit signal and power line, standby current, the ground lost, internal dielectric strength, operations with/without functional limitation, over-voltage range, and under-voltage range tests.   Tolerances & Standard Values Frequencies ±1% Temperatures ±2 °C Humidity ±5% Times/durations +5%; 0% Voltages ±0.5% Currents ±2% Room Temperature TRT = 23 °C ± 5 °C Humidity 25 % (+ 5 % bis 0 %) to 75 % (- 5 % bis 0 %) Test Temperature Ttest = TRT Operating Voltage U48max Source Impedance 10 mOhm ≤ Ri ≤ 100 mOhm   Terms A, B, C, D in Diagrams Functional status A, B, C,
