Description |
Validation Range |
Units |
| Temp |
System reference temperature – used for noise power calculations. (-273.15 is absolute zero) |
-273.14 to +1000 |
°C |
| Min SNR |
Minimum system SNR used to calculate the dynamic range (SDR) |
-100 to +100 |
dB |
| Use VSWR |
Determines whether the interface VSWR mismatch errors are included in the cascaded Gain equation, which
in turn affects every other equation in the system. |
“y” or “Y” to include “n” or “N” to exclude |
- |
| Freq. Units |
Select frequency units for use in noise and BW calculations. |
Any upper or lower case form of ‘kHz,” “MHz,” or “GHz” |
- |
| P[input] |
Signal power level at system input |
-1000 to +1000 |
dBm |
