TSTamp is also available for buffer readings. TSTamp can be referenced to the first reading stored in
the buffer (absolute format) which is time stamped at 0 seconds, or can provide the time between
each reading (delta format). The :TRACe:TSTamp:FORMat command is used to select the absolute
or delta format. For the delta format, real-time time stamp is expressed as the days, hours, minutes
and seconds between each reading, while the relative time stamp is expressed as seconds between
each reading. When using the absolute format for the relative time stamp, any pre-trigger readings
have a negative time stamp.
STATus: This element indicates if the reading is normal (N), overflowed (O) or referenced (R) to
another value, zero (Z), underflow (U), or out-of-limits (L). This element is not available for the binary
formats.
HUMidity: Relative humidity can be read by connecting and enabling the Model 6517-RH humidity
probe to the instrument. The humidity probe is enabled or disabled from the :SYSTem Subsystem. A
reading of 999.99 means humidity is disabled. This data element includes the humidity reading (in %)
in the data string.
ETEMperature: External temperature can be measured by connecting (and enabling) the Model
6517-TP temperature sensor to the instrument. The temperature sensor is enabled or disabled from
the :SYSTem subsystem. A reading of 9999.99 means temperature is disabled. This data element
includes the temperature reading (in °C, °F, or K) in the data string. Temperature units are selected
from the :UNIT subsystem.
VSOurce: This element indicates the voltage that is being sourced by the V-source. In standby, 0 V is
sourced.
The ASCII format shown in the "ASCII data format" figure (see [:DATA] <type>[,length] (on page 14-
51)) shows the byte order of the data string. The byte order can only be reversed for the binary
formats.
When using this command to add an element, you must include all elements that you want in the
format. For example, if the reading is already specified and you want to add the time-stamp, you must
include the READing parameter. :form:elem time, read.
Data elements for the item list can be listed in any order, but are always sent in the order shown in
the "ASCII data format" figure.
