AVERAGES
--_,
Type:
Setting or Query
Setting Syntax:
AVE <number>
or
AVGS <number>
Examples:
AVE -1
AVGS 1 .EI+2
AVERAGES 100
Query Syntax:
AVE? or AVGS?
Query Response:
AVE -1;
AVE 1 .Ed-4;
Discussion:
The AVERAGES command sets the minimum number of
events to be counted on Channel A before calculating mea-
surement re!jults. Valid <number> arguments are:
<number> GO
-
Sets DC 5010 to "auto-averagesn
mode. In "auto-averages", the instrument accumulates
counts for e . 3 seconds.
When in "auto-averagesn query returns AVE
-
1.
<number>
=
1, I.E+1, l.E+2, l.E+3, l.E+4,
l.E+5, l.E+6, l.E+7, l.E+8, l.E+9.
The argument <number> is first rounded to the nearest
power of ten. If the resulting value is not one of the above
valid values, the averages setting is left unchanged and an
execution error (ERR 205) is issued.
The AVERAGES setting is also used to scale the dis-
played results for TOTALIZE measurements. Results output
to the IEEE-488 bus, however are not scaled.
The power-on initial settings is AVE -1.
AVERAGES
CHANNEL (CHANNEL SELECT)
Type:
Setting or Query
Setting Syntax:
CHA A
B
Examples:
CHANNEL A
CHA B
Query Syntax:
CHA?
Query Response:

settings commands are SLOPE, SOURCE, ATTENUATION,
COUPLING, and LEVEL. Valid arguments are:
A
-
Channel A is affected by input setting commands.
B
-
Channel B is affected by input setting commands.
The power-on initial setting is CHA A.
