Value measured with untuned input.

NF meter direct-reading value (DSB measurement).

Value with a desired reception signal input level of –30 dBm, an interference signal of 100 kHz/30 % AM,

and an interference signal level where S/I=46 dB measured with a spectrum analyzer.

Value which is measured as 420 Ω load impedance and compensated loss by 180 Ω resistor connected to

Pins 19 and 20.
