MATH<x>:NUMAVg
Description
This command sets or returns the acquisition number at which the aver-
aging algorithm will begin exponential averaging. Prior to that acquisi-
tion number, the algorithm uses stable averaging. This has no affect
unless the AVG() function is used in the specified math expression. If
so, it affects all AVG() functions in this math expression. The Math
waveform is specified by x, which ranges from 1 through 4 for four--
channel instruments or 1 through 2 for two--channel instruments. This
command is equivalent to selecting Set Math Averages from the Math
menu and then entering an averaging value for the math waveform.

Syntax 2
MATH<x>:NUMAVg?
Argument
H <NR1>
This specifies the number of acquisitions over which exponential av-
eraging is performed.
Example 1
MATH2:NUMAVg 10
This command averages the Math 2 waveform ten times.
Example 2
MATH2:NUMAVg?
This query might return
:MATH2:NUMAVG 10
indicating that ten Math 2 waveforms are averaged before a single ac-
quisition occurs.
