First, we will discuss spectrum analyzer sensitivity in terms of its noise floor and then go into actual noise measurements. A low noise floor indicates good sensitivity and is necessary for measuring the noise factor of an amplifier. Fig. 6-1 ~ Spectrum analyzers. Left: Agilient N9342C Handheld Spectrum Analyzer (HSA) weighs 3.2 kg.

The ZTX851's are 0.275nV/√Hz or so at 10mA, and a differential pair like this with 3.3 ohm emitter resistors gives about 0.5nV/√Hz floor for measurements. The supply is two 9V batteries, the 1.8V is actually a red LED as a voltage source. I have a Scarlett Solo 3rd gen USB sound card which is 1.5nV/√Hz on the microphone input at max gain.
