:DATA command
:DATA?
[:SENSe[1]]:DATA? Return reading
Description This query command is used to read the latest instrument reading. This
command returns the “raw” reading or a reading that is the result of the
Reference (REL from the front panel) operation. For example, if a reference
value of 1.0 is established, the reading returned by this command is the “raw”
reading minus 1.0. Calculated (MATH) readings cannot be read with this
command (see the CALCulate subsystem for information on how to read
math calculations).
The reading is returned in exponent form. For example, a 10V DC reading
will be displayed on the CRT as follows: +1.000000E+01
Notice that the measurement function is not included in the response
message. Thus, you may want to perform a function query (see previous
command) after a reading query.
:HOLD command
The following commands are used to configure and control the Hold feature.
For details on Hold, refer to “Trigger Model, Device Action” in this section
and “Hold” in Section 3.
:WINDow <NRf>
[:SENSe[1]]:HOLD:WINDow <NRf><name> Set Hold window
Parameter <NRf> = 0.01 to 20 Set window (percent)
Query :WINDow? Query Hold window.
Description This command is used to set the window for Hold. The window is expressed
as a percent of the “seed” reading for the Hold process.
:COUNt <NRf>
[:SENSe[1]]:HOLD:COUNt <NRf> Specify Hold count
Parameter <NRf> = 2 to 100 Specify Hold count
Query :COUNt? Query Hold count.
Description This command is used to specify the count for Hold. Count is the number of
readings that are compared to the “seed” reading during the Hold process.
