I am using an FFT function from a NI driver API and the elements in the output array are in units of dB (decibels). How do I convert these values to dBm instead of dB. SolutionIn any measurement application, a decibel is a unitless ratio. Decibels are always a reference to some ...

To convert milliWatts to Watts just subtract 30 (since 30 dBm = 1,000 mW = 1W) 55dBm = 25 dB 35 dBm = 5 dB 25 dBm = -5dB To convert Watts to milliWatts just add 30 (since 30 dBm = 1,000 mW = 1W) 35 dB = 65 dBm 15 dB = 45 dBm 3 dB = 33 dBm111...
If the spectrum of the IF output is viewed in Swept SA measurement, there will be an “Input Overload” warning (Figure 6a) with the same hardware setting as in Noise Figure measurement. When LO input power is 5 dBm, the leakage to IF Output is about -11 dBm at the higher frequency ...
DBM files are between 24 KB and 410 KB in size. The following filename is common: TOOLDATA.DBM or MACROVAR.DBM. These files are attributed to toolofs. All other DBM files (80%) have different formats, often e.g. JetDB, SQL, DBM and DLBM. The category is programmliste, list, ...
(fSAMPLE/2) of the ADC. SNR is typically defined for a continuous sinewave signal applied to the ADC input at some level below the full-scale (FS) level of the converter, usually 0.5dB to 1dB. The ADC converts the signal into discrete output levels using a nonlinear process. The ...

frequency. This attenuator has approximately 15 dB of digital step attenuation range. As the output frequency sweeps from 10 GHz to 40 GHz, this attenuation should be decreased to maintain the desired output power flatness vs. frequency. This results in a nominal PA output power of ...
and accounts for the noise in the roll-off region. The shape factor, which depends on the order of the filter, is the ratio of the noise bandwidth to the –3-dB bandwidth.3The more poles in the filter, the closer the shape factor is to unity. This relationship can be seen in Table...
