1. Does the DG series product have power output functionality?
No, after being equipped with PA1011, it can achieve 10W power output.
2. When switching the output impedance between high impedance and 50 ohms, why is there no change in the output?
This is because the physical output impedance of the signal source is fixed at 50 ohms, and the condition of the output impedance is only adjusted through software to regulate the size of the signal source's output value.
Firstly, when switching the output impedance, the amplitude setting of the signal will change accordingly. For example, for a 1KHz, 2Vpp square wave with high impedance output, if we switch to 50 ohms, the setting becomes a 1KHz, 1Vpp square wave. However, if we still set the input impedance of the oscilloscope to high impedance to observe this signal, the measured result will still be a 1KHz, 2Vpp square wave. This is due to the mismatch between the input impedance of the oscilloscope and the output impedance of the signal source.
At this point, we need to adjust the input impedance of the oscilloscope to 50 ohms to get the correct measurement result, which should be a 1KHz, 1Vpp square wave.
3. What should I do if the DG output becomes inaccurate after some time of use?
