Advanced Measurement Kit - SW option

DSA800-AMK option provides various measurement functions, including T-Power, ACP (Adjacent Channel Power), Chan Pwr (Channel Power), OBW (Occupied Bandwidth), EBW (Emission Bandwidth), C/N Ratio, Harmo Dist (Harmonic Distortion) and TOI (Third Order Intermodulation). For advanced measurement functions, the measurement mode can be single or continuous and you can control the measurement including Restart, Pause and Resume.

Press Meas at the front panel and then press Meas Fctn to select a measurement function. The screen is divided into two windows with the upper window (the basic measurement window) displaying the sweep trace and the lower window displaying the measurement results.

• T-power
  The system enters zero span mode and calculates the power within the time domain.The types of powers available include Peak, Average and RMS.

• ACP 
  Measure the powers of the main channel and adjacent channels as well as the power difference between the main channel and each of the adjacent channels. When this function is  enabled,  the  span  and  resolution  bandwidth of the analyzer are adjusted to smaller values automatically.

• Chan Pwr 
  Measure the power and power spectral density within the specified channel bandwidth. When this function is enabled, the span and resolution bandwidth are automatically adjusted to smaller values.

• OBW 
  Integrate the power within the whole span and calculate the bandwidth occupied by this power according to the specified power ratio. The OBW function also indicates the difference between the center frequency of the channel under measurement and the center frequency of the analyzer.

• EBW 
  Measure the bandwidth between two points on the signal which are X dB below the highest point within the span.

• C/N Ratio 
  Measure the powers of the carrier and noise with the specified bandwidths as well as their power ratio.

• Harmo Dist 
  Measure the power of each order of harmonic and THD (total harmonic distortion) of the carrier. The highest order of harmonic available is 10 and the fundamental  wave amplitude must be greate than -50 dBm, or else the measurement will be invalid.

• TOI  
  Measure the parameters of the TOI production of two signals with the same amplitude and similar frequency. Those parameters include the frequencies and amplitudes of the Base Lower, Base Upper, 3rd Order Lower and 3rd Order Upper signal, as well as the Intercepts of both the Base Lower and Base Upper.
