Attribute Summary:

Description:

The frequency spacing between measurement points is adjusted automatically by the analyzer. The

analyzer increments or decrements the size of the step to accommodate varying frequency response

The analyzer calculates the ratio of the frequency response of the current point to the frequency response

of the previous point. If the ratio exceeds the maximum percentage change specified by the

FREQ:RES:AUTO:MCH command, the analyzer adjusts the resolution to measure the next point.

The adjusted resolution value is never less than the minimum resolution value specified by the

FREQ:RES:AUTO:MIN command. The initial resolution of the sweep between the first two points is

specified by FREQ:RES:AUTO:MIN.

FREQ:RES:AUTO is ON after a reset (*RST).

See table 18-5 to determine the number of displayed data points with swept sine variable resolution.
