Buffer
6-7
•
STATus — Includes a status word for each reading. It provides status information
on instrument operation. (See
.)
•
At least one data element must be in the list. Listed elements must be separated by
a comma (i.e. FORMat:ELEMents, READing, TIME). Elements not listed will not
accompany the response message for TRACe:DATA?. Data in the response mes-
sage will be in order of the listed data elements set by this command.
G) CALCulate3:FORMat <name>
This command selects the statistic to be returned by CALCulate3:DATA? (see Ref H).
Name parameters:
•
MINimum — Select the lowest reading stored in the buffer.
•
MAXimum — Select the largest reading stored in the buffer.
•
MEAN — Select the mean average statistic for the readings stored in the buffer.
•
SDEViation — Select the standard deviation statistic for the readings stored in the
buffer.
•
PKPK — Select the peak-to-peak statistic for readings stored in the buffer. Peak-to-Peak
is calculated as follows: PKPK = MAXimum - MINimum.
H) CALCulate3:DATA?
1.
If the number of data points in the buffer is one or none, CALCulate3:DATA? will
result in an error (-230).
2.
If there is a lot of data in the buffer, some statistic operations may take too long and
cause a bus time-out error. To avoid this, send calc3:data? and then wait for the
MAV (message available) bit in the Status Byte Register to set before addressing
the Model 6485 talk (
