SPECtrum:FREQuency:SAMPle?
Queries the sample rate with which FFT analysis is performed. This command is only
available in FFT mode.
Return values:
<FFTSmpFreq> Range: 1 to 10E+9
Increment: 10
*RST: 1
Default unit: Hz
Usage: Query only
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.
