The Bird 4431 RF Sampling Wattmeter is the same as
the Bird Model 43 Thruline 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.
