# How to know the time of my window to calculate the STFT with python knowing only the length?

I am trying to implement a work presented in an IEEE paper where they have mentioned that the STFT was performed on the signal measurements to obtain a spectrogram with no overlap window of 3 min :

I have used the following code :

f, t, STFT = sc.signal.stft(phase_meas, fs=1.0, window=????, nperseg=180, noverlap=None,
