摘要:The model 3170B dual-meter wattmeter from Bird Technologies Group provides accurate power measurements of RF sources between 450 kHz and 2.7 GHz and generating between 100 milliwatts and 10 kilowatts. Its dual-meter display allows simultaneous display of forward and reflected power.The unit can...
A forward/reverse power check with an in-line wattmeter should show no more than 10% reflected power. For the following tests, insure that the power switch is in the high position. METHODOLOGY Most of the EMI tests can be accomplished on the ground. In some cases flight testing is ...
