TSP command reference

When there are outstanding overlapped commands to acquire data, n refers to the index that the last entry in the
table will have after all the readings have completed.
If you pass a reading buffer instead of a reading buffer subtable, the default subtable for that reading buffer is
used.
This command generates a single response message that contains all data.
The format.data attribute controls the format of the response message.
You can use the bufferVar attributes that are listed in the following table with the print buffer command. Add
them after the bufferVar parameter.
Attribute Description
bufferVar.n
The number of readings in the specified buffer. See
bufferVar.n (on page 8-23).
bufferVar.readings
The readings stored in a specified reading buffer. See
bufferVar.readings (on page 8-24).
bufferVar.dates
The dates of readings stored in the reading buffer. See
bufferVar.dates (on page 8-18).
bufferVar.statuses
The status values of readings in the reading buffer. See
bufferVar.statuses (on page 8-33).
bufferVar.formattedreadings
The stored readings formatted as they appear on the
front-panel display. See bufferVar.formattedreadings
(on page
8-20).
bufferVar.sourceformattedvalues
The source levels formatted as they appear on the front-panel
display when the readings in the reading buffer were acquired.
See bufferVar.sourceformattedvalues (on page 8-28).
bufferVar.sourcevalues
The source levels that were being output when readings in the
reading buffer were acquired. See bufferVar.sourcevalues (on
page 8-32).
bufferVar.sourcestatuses
The source status conditions of the instrument for the reading
point. See bufferVar.sourcestatuses (on page 8-29).
bufferVar.times

(on page 8-30).
bufferVar.seconds
The nonfractional seconds portion of the timestamp when the
reading was stored in UTC format. See bufferVar.seconds (on
page 8-26).
bufferVar.fractionalseconds
The fractional portion of the timestamp (in seconds) of when
each reading occurred. See bufferVar.fractionalseconds (on
page 8-21).
