Function Commands
:FUNCtion<F>:FFT:RESolution?
Query
:FUNCtion<F>:FFT:RESolution?
The :FUNCtion<F>:FFT:RESolution? query returns the current resolution of
the FFT function.
Returned Format
[FUNCtion<F>:FFT:RESolution] <resolution_value><NL>
<F> An integer, 1- 16, representing the selected function.
<resolution
Resolution frequency.
_value>
The FFT resolution is determined by the sample rate and memory depth
settings. The FFT resolution is calculated using the following equation:
FFT Resolution =
The effective memory depth is the highest power of 2 less than or equal to
the number of sample points across the display. The memory bar in the
status area at the top of the display indicates how much of the actual
memory depth is across the display.
