User Manual 1317.4726.02 ─ 01
Parameters:
<Magnitude Scale>
LINear | DBM | DBV
LINear
linear scaling; displays the RMS value of the voltage.
DBM
logarithmic scaling; related to 1 mW
DBV
logarithmic scaling; related to 1 Veff
*RST:
DBM
Example:
CALC:MATH:FFT:MAGN:SCAL DBM
CALC:MATH:SCAL 20
Set the Y-scale of the FFT window to 20 dBm.
CALCulate:MATH<m>:FFT:BANDwidth[:RESolution]:ADJusted?
Queries the effective resolution bandwidth.
Suffix:
<m>
.
1..4
The numeric suffix is irrelevant.
Return values:
<AdjResBW>
Range:
Depends on various other settings.
Default unit: Hz
Usage:
Query only
CALCulate:MATH<m>:FFT:BANDwidth[:RESolution]:AUTO
<SpanRBWCoupling>
Couples the frequency span to the RBW.
Suffix:
<m>
.
1..4
The numeric suffix is irrelevant.
Parameters:
<SpanRBWCoupling> ON | OFF
CALCulate:MATH<m>:FFT:BANDwidth[:RESolution]:RATio
<SpanRBWRatio>
Defines the ratio of span (Hz) / resolution bandwidth (Hz). The span/RBW ratio is half the
number of points used for FFT which is defined with manual operation in the menu.
Suffix:
<m>
.
1..4
The numeric suffix is irrelevant.
Parameters:
<SpanRBWRatio>
Range:
The value is changed in 2^n steps from 2^10 to 2^15
(1024, 2048,4096,8192,16384, 32768).
