Input Impedance
In this window, it is possible to re-adjust the internal input resistor, which should be matched to 50
Ω
.
The procedure is similar to the previous ones:
- select the channel where you need to adjust the input impedance;
- check that the channel is ON and READY (green LEDs);
- enter the resistor value;
- push the WRITE button to write these values to the internal registers (you can retrieve the
initial value of the impedance by clicking on the CANCEL button).
This function helps to re-adjust the input impedance in case of a slight mismatch due to temperature
variations or process variations.
