9.6 Setting the input impedance compensation
1. F6 to select the input impedance compensation.
50Ω 75Ω
When a coaxial adaptor (50Ω/75Ω impedance converter) is attached, and choose “75Ω”, then
offset is calculated to the reference level, and it changes for the measured value as 75Ω system, and
display it.
* When “75Ω” is selected, “75Ω” is displayed in the LEVEL area on the screen. When “75Ω” is
selected, the offset is set to 5.7dB (insertion loss of adapter).
Moreover, can set offset.
Moreover, while setting the unit of the marker point to [W, V, V/m] etc, it changes from dBm
correctly.
* When you set it as “75Ω”, please be sure to attach the coaxial adapter (50Ω/75Ω
impedance converter).
10. Display Scale <SCALE>
Press to switch over to the function screen shown below:
10.1 Setting with the keys ([F1], [F2])
1. Press to set the 10dB/div display scale.
2. Press to set the 2dB/div display scale.
10.2 Setting with the encoder
1. Turn to switch between the 10dB/div and 2dB/div display scale.
10dB 2dB
* In 2dB/div, display level may not become smaller than fixed level, by frequency
compensation.
