SENSe:MBUF:POSition
Description:
Return the current acquisition position into the measurement buffer, which is the index of
the next buffer point which will be written to. This command is useful for determining
whether the measurement buffer is full. A value of zero indicates that no points have been
buffered yet, and a value of RATE indicates that the buffer is full.
Syntax:
SENSe[1|2]:MBUF:POSition?
Returns:
current index value, 0 to 4096
Valid Modes:
Modulated, CW or Pulse modes
SENSe:MBUF:COUNt
Description:
Set or return the number of measurement buffer readings which will be returned each time
the
SENSe:MBUF:DATA?
query is issued when the measurement buffer is active. At the
completion of each read, INDEX is automatically incremented by COUNT. If COUNT is set
to a number greater than the number of points remaining in the measurement buffer, the
array will be truncated. Setting COUNT to SIZE will return the entire measurement buffer.
Syntax:
SENSe:MBUF:COUNt
Argument:
Valid Modes:
Modulated, CW or Pulse modes
SENSe:MBUF:INDEX
Description:
Set or return the array index for the first measurement buffer point to be returned next time
the
SENSe:MBUF:DATA?
query is issued. Index 0 corresponds to the first point in the
buffer, and index SIZE-1 is the last. 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 manage-
able size and read with successive
SENSe:MBUF:DATA?
queries. INDEX must be reset
to zero for each new measurement buffer that is to be dumped, whether or not the entire
buffer has been read.
Syntax:
SENSe:MBUF:INDEX
Argument:
Valid Modes:
Modulated, CW or Pulse modes
SENSe:MBUF:DATA
Description:
Return a comma-delimited array of power readings corresponding to all or a portion of the
measurement buffer for the selected channel. The array will consist of COUNT buffer
points, beginning at point number INDEX. Power is returned in currently selected units for
that channel.
Syntax:
SENSe[1|2]:MBUF:DATA?
Returns:
P(index), P(index+1), P(index+2).... P(index+count)
Valid Modes:
Modulated, CW or Pulse modes,
SENSe:MBUF:SIZe
must be >0.
