According to transformation mode selected, the Analyzer calculates low pass impulse, low pass step or band pass impulse
response by the use of frequency domain data.

Useful Data Format
8.6.5.1.
Useful data format in band pass mode
Linear amplitude format
For reflection Measure, this format represents the average amplitude of reflection coefficient (ρ) within the whole Measure
frequency range.
For transmission Measure, this format represents the average transmission coefficient (τ) of the transmission path within
the whole Measure frequency range.
This format is very useful to observe the response with similar amplitudes.
Log-magnitude format
For reflection Measure, this format represents return loss (dB) and the display value represents average return loss of
discontinuous points within the whole Measure frequency range.
For transmission Measure, this format represents transmission loss or gain (dB) and the display value represents average
loss or gain of the transmission path within the whole Measure frequency range.
This format is very useful to observe the response of dynamic range.
Standing wave ratio
For reflection Measure, this format represents the average value of standing wave ratio of the discontinuous points within
the whole Measure frequency range.
8.6.5.2.
Useful data format in band pass mode
Real part
This format utilizes real part unit to represent response of the measured piece.
