7.2 Measurement of the RF Signal Voltage Level and DC Output of the Voltage Level
Explanation
7-8
Do not apply external voltage to the output terminal. This may cause damage to
the TA220.

Setting Menu for Voltage Level DC Output
The following setting parameters are available for DC output of the RF signal voltage
level. Use the rotary knob to select the parameter you wish to set.
• Lv meas: Turns voltage level measurement ON and OFF
• Lv mode: Selects the voltage level DC output mode
• LevelHi: Sets the upper limit of the voltage level DC output range
• LevelLo: Sets the lower limit of the voltage level DC output range
• LvJdgHi: Sets the upper limit of the voltage level determination range
• LvJdgLo: Sets the lower limit of the voltage level determination range
• Lv ave: The average coefficient for DC output of the voltage level
Turning Voltage Level Measurement ON and OFF
You can select whether or not (ON or OFF) to measure the voltage level of the RF
signal. When turned ON, the numerical display of measured results parameter "LV
(voltage level)"is added (see section 5.2).
