RSP1A Noise Figure

Postby Niscom32 » Thu Jun 21, 2018 10:21 pm

Using a calibrate 15.2dB ENR noise source, running SDRuno I measured the following noise figures of my RSP1A.
IF AGC was on, RF gain reduction was 0, total gain reduction was reported as 20dB.

MHz __ NF dB
1.900 __ 20.6
3.600 __ 21.1
7.100 __ 17.8
14.200 __ 16.5
21.300 __ 16.3
28.500 __ 17.5
50.500 __ 17.7
70.500 __ 4.1
93.500 __ 3.9
145.500 __ 3.9
162.025 __ 3.8
225.500 __ 4.0
275.500 __ 9.5
350.200 __ 9.5
700.000 __ 6.4
918.000 __ 5.7
1090.000 __ 8.2
1227.600 __ 8.4
1296.200 __ 8.9
1400.000 __ 7.9
1575.420 __ 7.8
1990.000 __ 10.6


Note the noise source calibration was not valid below 10MHz.

Not to far off the quoted spec, I thought this may be of interest.
