Input Impedance 
 
Sets the input impedance to 75Ω or 50Ω.  
> More[F7]> More[F7] > Input Z[F1] 
to toggle the input impedance.  
Input Impedance Calibration 
 
When an external impedance converter module 
(optional accessory ADP-101) is used to convert 
the impedance of a device from 50Ω to 75Ω, 
some external loss can be induced. The Input Z 
Cal function can be used to compensate for 
these losses with an offset value.  
The Input Z Cal function is only functional when 
the input impedance is set to 75Ω. 
> More[F7]>More[F7]>Input Z 
Cal[F2] and set the impedance offset. 
The AMP icon is displayed at the bottom 
of the screen when Input Z Cal0dB and 
Input Z is = 75Ω.
