In our organization,  we have the following specification NOISE FIGURE ANALYSER

*N8973A (10MHz - 3GHz) NOISE FIGURE ANALYSER and NOISE SOURCE is 346B (10MHz-18GHz) nominal ENR 15dB.*

My question is, from the above specification NOISE FIGURE ANALYSE R and NOISE SOURCE. We are able to measure the 0.1 dB or 0.2 dB or 0.3 dB or 0.4 dB or even less than  0.2 dB noise figure. Because We have designed the Low Noise Amplifier (LNA) with 0.2 dB noise figure.

If it is not possible, which number NOISE FIGURE ANALYSER and NOISE SOURCE is used for measuring the  Noise figure less than 0.2 dB.
