Load
To understand how to set the load, we first need to understand how the voltage of the output
port is obtained (

the load R

Where Vs is the output voltage of the signal source before the output impedance Rs. Since the
signal source cannot automatically identify the value of RL, the user needs to inform the signal
source of the value by inputting the "load" value, and then the signal source calculates the Vs
according to the RL and Vo set by the user so that the Vo obtained by the user is consistent with
the expected value under any load.
Waveform Parameters
The parameters that can be set for each standard wave are different, as shown in the table below:

Sine
Frequency/
Period
Frequency/period of the signal. The unit of frequency is Hz and
the unit of period is s. The relationship between the two is:
Frequency = 1/period
