DATA:COUNt?
DATA:CVTable?
Parameters
Comments
# signifies a block transfer
<num_digits> is a single digit (1 through 9) which specifies how many digits
(ASCII characters) are in the <num_bytes> descriptor which follows
<num_bytes> is the number of data bytes which immediately follow the
<num_bytes> field
•
A full scale reading may actually be an overload.
•
A deadlock can occur when trigger events are set to BUS or HOLD because a
software trigger could not break in after this command is sent.
•
Executable when initiated: Yes
•
Coupled command: No
•
Reset (*RST) condition: none
[SENSe:]DATA:COUNt? command returns the number of readings available to be
read by the DATA? command per channel. This is useful for determining the
amount of data taken in an aborted measurement. The data count from a completed
measurement is equal to the sample count set by the SAMPle:COUNt command.
[SENSe:]DATA:CVTable? @channel_list command returns the most recent
reading taken from each specified channel. The last reading, or Current Value, from
each channel is returned in channel number order starting with the first one in the list.
Parameter
Name
channel_list
•
channel_list has the form (@1) or (@2), (@1,2), (@1:4) or (@1,2,3,4) or for
specific channels but not all, the format is (@1,3,4). If you specify channels
not in ascending order e.g., (@2,1) or (@3,4,2), they are rearranged as 1,2 or
2,3,4 respectively.
•
Data is returned as raw data (16-bit integers) when the data format is set to
PACKed (see the FORMat[:DATA] PACKed command). Use either of the
two methods shown below to convert the raw readings to voltages:
voltage = reading * range/32768
voltage = reading * resolution
