Broadband RF Wattmeter with Variable Sample Port
Bird 4431 RF 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.
