Note: CALCulate commands act on the selected measurement. You can
select one measurement for each channel using Calc:Par:MNUM
or Calc:Par:Select. Learn
more.
If
you use Calc:Par:Cat? to return the list
of current measurements, the returned string will be similar to ‘CH1_B_1,B’.
To select this measurement
as a parameter for SA, you need to send Calc:Par:Sel ‘CH1_B_1’.
Moreover,
most of the following commands will return ‘+202, “Parameter not valid”
if they are called with marker number n, and marker number n is not currently
turned ON.
Important: Learn about programming the reference marker.
Note: For all band
power marker family (this includes BNOise, BPOWer, OCCBand markers) and
when measuring wideband repetitive modulated signals, there is basically
2 approaches to get good measurements:
- Either run
the coherent mode of SA if the modulated test signal repetition period
or tone spacing is known and a frequency reference connection is made
between the signal source and the PNA (usually the 10 MHz ref signal BNC).
See SA Setup Coherence.
- Or
make use of a RBW that is equal or smaller than 1/20 of the modulated
test signal tone spacing (rule of thumb). The test signal tone spacing
is 1/ the test signal duration. For example, if the ARB file that generates
the test signal replays each 100 microseconds, it means the tone spacing
is 10 kHz. So, we recommend to set the RBW to 500 Hz or below.
(Read-only) Returns the band noise level in dBm/Hz from the band noise marker. |

Parameters |
|
<ch> |
Channel number of the measurement. There must be a selected measurement on that SA channel. If unspecified, <ch> is set to 1. |
<n> |
Band noise marker number. If unspecified, <n> is set to 1. |
Examples |
CALC:SA:MARK:BNO:DATA? calculate2:sa:marker2:bnoise:data? |
Not applicable |
|
(Read-Write) Sets and reads the frequency span of the band noise marker. This area is marked by two vertical dotted lines on the screen and the marker's y-axis value is set to the measured power value. Noise and power on the same marker share the same span. |

Parameters |
|
<ch> |

<n> |
Marker number. If unspecified, <n> is set to 1. |
<num> |
