SENSe:HIST:COUNt
Description:
Set or return the number of histogram elements (bins), which will be returned each time the
SENSe:HIST:DATA?
query is issued. At the completion of each read, INDEX is automati-
cally incremented by COUNT. If COUNT is set to a number greater than the number of
points remaining in the histogram, the array will be truncated. Setting COUNT to 4096 (and
INDEX to zero each time) will return the entire histogram array. Setting COUNT to zero will
return a single point, but does not increment INDEX, and can be used to repeatedly query
the same histogram bin.
Syntax:
SENSe:HIST:COUNt <n>
Argument:
<n> = 0 to 4096
Valid Modes:
Statistical mode only.
SENSe:HIST:INDEX
Description:
Set or return the array index for the first histogram element (bin) to be returned next time the
SENSe:HIST:DATA?
query is issued. Index 0 is the first bin in the histogram, and corre-
sponds to the lowest power level in the power calibration table. Index 4095 is the last bin,
and contain counts for the highest power level. Each time a block of data is read, INDEX is
automatically incremented by the COUNT value, so the full array can be split up into blocks
of manageable size and read with successive
SENSe:HIST:DATA?
queries. INDEX must
be reset to zero for each new histogram that is to be dumped, whether or not all the bins
have been read.
Syntax:
SENSe:HIST:INDEX <n>
Argument:
<n> = 0 to 4095
Valid Modes:
Statistical mode only.
SENSe:HIST:DATA
Description:
Return a comma-delimited array of integer counts corresponding to all or a portion of the
statistical mode power histogram for the selected channel. Each bin is 32 bits wide, and may
consist of a number from zero (indicating no hits to that power level) to 4 billion (indicating
all hits in the histogram were at that power level). The array will consist of COUNT histo-
gram bins, beginning at bin INDEX, up to the last bin of the histogram (index = 4095).
Syntax:
SENSe[1|2]:HIST:DATA?
Returns:
N(index), N(index+1), N(index+2).... N(index+count)
Valid Modes:
Statistical mode only.
SENSe:CALTAB:COUNt
Description:
Set or return the number of caltable entries, which will be returned each time the
SENSeCALTAB:DATA?
query is issued. At the completion of each read, INDEX is auto-
matically incremented by COUNT. If COUNT is set to a number greater than the number of
points remaining in the caltable, the array will be truncated. Setting COUNT to 4096 (and
INDEX to zero each time) will return the entire caltable array.
Syntax:
SENSe:CALTAB:COUNt <n>
Argument:
<n> = 0 to 4096
Valid Modes:
Statistical mode only.
