5.5.12 SetGamma and GetGamma Method
Method:
SetGamma( magnitude, phase )
GetGamma( magnitude, phase, loss)
Parameter:
magnitude [in][out]
phase [in][out]
loss [out]
Magnitude of reflection coefficient
Phase of reflection coefficient
Loss of tuner (and adapter) in dB
Return value:
Result value of command (see command description in chapter 4)
Remarks:
SetGamma encapsulates the ‘TuneTo’ command.
GetGamma encapsulates the ‘GAMMA?’ command.
SetGamma() is a blocking command (if Timeout property > 0).
GetGamma returns the instantaneous reflection coefficient in the DUT reference
plane, and can be called even while the tuner is performing a movement.
Examples:
iTuner.SetGamma(0.2,135)
iTuner.GetGamma(&mag,&phase,&loss)
5.5.13 GetGammaAt Method
Method:
GetGammaAt(x,y, magnitude, phase, loss)
Parameter:
x [in]
y [in]
magnitude [out]
phase [out]
loss [out]
Position of horizontal axis
Position of vertical axis
Magnitude of reflection coefficient
Phase of reflection coefficient
Loss of tuner (and adapter) in dB
Return value:
Result value of command (see command description in chapter 4)
