Points (Only for DSA832/DSA875/DSA832E)
Set the desired points for every sweep. That is the number of points of the current
trace.
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 use the numeric keys, knob or direction keys to modify this parameter.
Please refer to "Parameter Setting" for more details.
