5-54
The second parameter specifies whether all the enabled voltage channels should remain on
after test completion.
The default action is to turn off all enabled channels on test completion.
The query form of the command also requires the mode parameter (i.e. MVOLtage? <cpd>).
It will return whether the specified mode has “maintain voltage” enabled.
Note
The energy “free-running” mode is not supported by this operation.
When “maintain voltage” is activated, and a test completes, a query using :OUTPut? will
report “1” or “ON” until a :OUTPut 0 is sent.
5-81. Energy units
ENERgy:UNIT(?) <cpd> { REAL|APParent|REACtive }
This command selects the base units used in energy counter/timer calculations.
• REAL Real power (Wh).
• APParent Apparent power (VAh).
• REACtive Reactive power (VARh).
5-82. Result presentation
ENERgy:PRESentation(?)
<cpd> { COUNts|ENERgy }, <cpd> { PERRor|PREGistration }
This command configures the presentation of displayed results. It also defines the meaning
the result fields returned by using the “:ENERgy:RESults?” command.
The first parameter defines the meaning of the MUT accumulated energy field:
• COUNts As raw counts.
• ENERgy As accumulated energy (using the base units defined by the
“ENERgy:UNIT” command).
The second parameter defines the meaning of the measured error field:
• PERRor As percentage error = ((MUT counts - ref. counts) / ref. counts) * 100.0.
• PREGistration As percentage registration = (MUT counts / ref. counts) * 100.0.
5-83. Results
ENERgy: RESults? <cpd> { CH1|CH2|CH3|CH4|CH5|CH6 }
This query only command returns the result data for the selected channel:
• 1st <dnpd> instantaneous Power or Frequency [1] (the power field’s units are implied
by the active “ENERgy:UNITS” definition).
• 2nd <dnpd> MUT accumulated Energy or Counts [1].
• 3rd <dnpd> Reference accumulated Energy or Counts [1].
• 4th <dnpd> Percentage Error or Registration [2].
[1] Second meaning applies when “PRESentation” is set to “COUNts”.
[2] Second meaning applies when “PRESentation” is set to “PREGistration”.
If the selected channel is inactive, a comma-delimited list of zero value <dnpd>s will be
returned. A “ENERgy: RESults?” query can be made at any time.
This command would typically be used in conjunction with the “STATus:OPERation”
