System-Related Functions

The analog signal bandwidth is less than 100Hz, and the signal bandwidth sup-

ports any waveform. When the programmed signal frequency or amplitude ex-

ceeds the output capacity, the instrument will automatically limit the output

amplitude. When the input voltage exceeds 10V, the set value will be limited in

the maximum rated value range.

input

• When CV is prioritized, input 0 –

10V voltage value to set the output

voltage between 0 and full scale;

• When CC is prioritized, input 0 –

10V voltage value to set the low

voltage limit (V_low value) between

0 and full scale;
