SPECtrum:FREQuency:SPAN:MODE <Mode>
Defines how many values are analyzed by a single FFT, and thus the frequency resolu-
tion.
Parameters:
<Mode> NARRow | MAX
NARRow
8k values analyzed per FFT; time scale ≥ 100 ms/div
MAX
64k values analyzed per FFT; time scale ≥ 1 us/div
*RST: MAX
SPECtrum:FREQuency:SPAN[:VALue]
<HorizontalSpan>
Queries or defines the used span, that is: how many values are analyzed by a single
FFT.
In FFT mode, this command is query-only.
Parameters:
<HorizontalSpan> 8E+6 | 64E+6
Range: 1000 to 500E+6
Increment: 10
*RST: 500E+6
Default unit: Hz
SPECtrum:FREQuency:STARt <HorizontalStart>
Queries or defines the start frequency of the used span. The value depends on the
SPECtrum:FREQuency:SPAN:MODE and CHANnel<m>:BANDwidth parameters.
In FFT mode, this command is query-only.
Parameters:
<HorizontalStart> Range: 0 to 499.999E+6
Increment: 10
*RST: 0
Default unit: Hz
SPECtrum:FREQuency:STOP <HorizontalStop>
Queries or defines the stop frequency of the used span. The value depends on the
SPECtrum:FREQuency:SPAN:MODE and CHANnel<m>:BANDwidth parameters.
In FFT mode, this command is query-only.
