Input Z 50Ω/ 75Ω

Keep pushing Input Z key will switch the input impedance between 50 and 75Ω. The prompted

message will appear that the “zz adaptor” should be connected.

Input Z Cal

UP/DOWN and Scroll: To change offset by 0.1dB for every move.

Editing: Editing keys can adjust the offset from -10.0 to 10.0dB in 0.1 dB resolution. The ideal

number is at 5.9dB

The “Input Z Cal” performs only when the input Z is at 75

Ω. In other words, when the input Z is

switched to 50

Ω, the calibration value will return to 0.
