Key Points:

Changing the points may influence the sweep time which is limited by the sample
rate of the ADC (Analog to Digital Converter). That is, the more points used, the
longer the sweep will be.

Changing the points would also influence other system parameters, thus the
instrument restarts the sweep and measurement cycle.

You can modify this parameter using the numeric keys, knob or direction keys.
For more details, please refer to “Parameter Input”.

Hint

The sweep points will automatically change to the maximum (3001) and the
menu is grayed out and disabled in Video trigger type.

With the increase (more than 601) of sweep points, the frequency resolution of
marker points increases and the sweep speed decreases.

In addition to the sweep points, other parameters such as span, resolution
bandwidth, video bandwidth, average detection method, and center frequency
can also influence the sweep speed.
