SCPI COMMANDS-
AVERAGING
COMMANDS These commands control the software averaging.
Since these commands are channel-specific the “#” in each command
should be replaced with the channel number 1,2 or 3. If the channel
number is omitted then Channel-1 is assumed.
:CALCulate#:AVERage:COUNt <NRf>
A new measurement is acquired approximately every 0.032 seconds.
The system requires a minimum of 6 measurements to be averaged,
which results in a new flux density reading every 0.2 seconds. For
greater stability the number of measurements to average can be
increased to 15, 30 or 60, resulting in new flux density readings every
0.5, 1 or 2 seconds, respectively.
Thus, <NRf> can be 6
(0.2 second update rate)
15 (0.5 second update rate)
30 (1.0 second update rate)
60 (2.0 second update rate)
:CALCulate#:AVERage:COUNt?
A new measurement is acquired approximately every 0.032 seconds.
The system requires a minimum of 6 measurements to be averaged,
which results in a new flux density reading every 0.2 seconds. For
greater stability the number of measurements to average can be
increased to 15, 30 or 60, resulting in new flux density readings every
0.5, 1 or 2 seconds, respectively.
This command returns the number of measurements being used for the
average, either “6”, “15”, “30” or “60”.
SCPI COMMANDS-
CLASSIFIER (LIMIT)
COMMANDS These commands control the CLASSIFIER, or limit checking function.
Two individual flux density limits can be specified. If the present flux
density reading becomes arithmetically less than the lower limit, or
arithmetically greater than the upper limit, the situation is considered to
be a “failure”.
Since these commands are channel-specific the “#” in each command
should be replaced with the channel number 1,2 or 3. If the channel
number is omitted then Channel-1 is assumed.
