Int Port Selection
1 2
Press this soft key to toggle the internal port selection to Port 1 or Port 2.
Int voltage P1
Press this soft key to set the internal bias tee voltage that is directed onto the center conductor of port 1. The available range is from 12.0 V to 32.0 V in increments of 0.1 V. Use the arrow keys, the rotary knob, or the number keypad to change the setting. When using the number keypad, press the soft key for voltage units (V), or press the Enter key. Press the Esc key to exit without changing the setting.
Int Current Limit P1
Press this soft key to set the internal bias tee current limit for the voltage that is set at Port 1. The available range is from 0 mA to 450 mA in steps of 1 mA. This current limit sets the trip point for the bias tee for this port. When using the number keypad, the soft key menu displays 2 choices for units: A or mA. Use the arrow keys, the rotary knob, or the number keypad to change the setting. When using the number keypad, press the soft key for current units (A or mA), or press the Enter key to use mA. Press the Esc key to exit without changing the setting.
Int voltage P2
Press this soft key to set the internal bias tee voltage that is directed onto the center conductor of Port 2. The available range is from 12.0 V to 32.0 V in increments of 0.1 . Use the arrow keys, the rotary knob, or the number keypad to change the setting. When using the number keypad, press the soft key for voltage units (V), or press the Enter key. Press the Esc key to exit without changing the setting.
Int Current Limit P2
Press this soft key to set the internal bias tee current limit for the voltage that is set at Port 2. The available range is from 0 mA to 450 mA in steps of 1 mA. This current limit sets the trip point for the bias tee for this port. When using the number keypad, the soft key menu displays 2 choices for units: A or mA. Use the arrow keys, the rotary knob, or the number keypad to change the setting. When using the number keypad, press the soft key for current units (A or mA), or press the Enter key to use mA. Press the Esc key to exit without changing the setting.
