美国鸟牌Bird【4431】通过式射频功率计,信号采样器功率分析仪
· The 4431 RF Sampling Wattmeter is the same as the model 43 General Purpose Wattmeter except for an
RF signal sampler probe. This RF probe provides a low power sample of the signal being measured and
is available at a female BNC connector on the right side of the housing. The signal level can be adjusted
with a control knob on the front of the meter. The sampled output can be connected to any
RF signal monitoring device such as a frequency counter, spectrum analyzer, or oscilloscope.
