Math Functions
The 553210A counter math functions include smoothing, null/scale, statistics,
and limit checking. Figure 6-1 is a description of how the functions are enabled.
The math functions are enabled at two levels: 1) the
CALCulate[1]
subsystem as a
whole is enabled, and 2) the individual math operation is enabled. Math
operations begin once the measurements are started either by
INITiate:IMMediate
or
READ?
, or as soon as the operation is selected from the
front panel (with internal triggering). Readings are processed real time and
displayed, stored in reading memory, and sent to the output buffer (they are not
post-processed from reading memory).
The number of readings processed for a given trigger cycle (
Chapter 5,
"Triggering and Gating" ) is determined by the trigger count (
TRIGger:COUNt
) and
the number of readings per trigger (
SAMPle:COUNt
). The default trigger count and
sample count set by each command is ‘1’ . Each time the counter is initiated
reading memory is cleared and a new set of math-processed data is generated.
From the front panel, readings are processed continually if the trigger source
remains at its default
INTernal
setting.
The math and graphics functions covered in this chapter are enabled individually
( Figure 6-1 ). However, multiple operations may be enabled at the same time and
performed on the same set of readings.
NOTE
The SCPI commands and parameters listed throughout this chapter are provided
as a guide to how the counter is operated programmatically. The commands are
described in detail in the ‘Programmer’s Reference’ section of the Keysight
53210A/53220A/ 53230A Product Reference CD.
