Note: If one of the source parameters has been changed after using this command a valid
default will be set (typically “MAIN”); so it is recommend that the “MUT:TEST:PSOUrce”
command is sent after any “MUT:SOURce” or “REFerence:SOURce” commands, to
prevent unexpected side effects.
The source can be:
• CH1 to CH6 Raw pulse streams from individual channels.
• SUM456 Sum of channels 4 through 5.
• MEAN456 Arithmetic mean of channels 4 through 6.
• MEAN56 Arithmetic mean of channels 5 and 6.
• EMUT On Every MUT channel. For example, on selecting a test
duration of 100 pulses, at least 100 pulses would have to be
counted on all selected MUTs before the test sequence was
considered complete.
• MAIN Equivalent pulse count of the power outputs (value calculated
from the “OUTPut:CONStant” meter constant value and active
power settings).
5-92. ENERgy: ABORt
This command allows an active test sequence to be aborted. Its action is similar to hitting
the ‘STBY’ key or sending ‘:OUTPut OFF’, with one exception: when the ‘Maintain
Voltage’ output feature has been enabled (ENERgy:ENERgy:MVOLTage), the voltage
channels will remain on (even though the test sequence has been reset to the beginning
again). If ':OUTPut OFF' is used to force a test sequence to stop, all channels will turn off
regardless of whether ‘Maintain Voltage’ has been set.”
5-93. MUT Tree
The MUT commands configure a MUT source. A MUT source is typically made up from
pulse streams from channels 1 to 3, though channels 4 to 6 can also be used when treated as
independent sources (i.e. for “drift monitoring”).
5-94. MUT Meter Constant
ENERgy:MUT:CONStant(?) <dnpd>
This command specifies the meter constant (as impulses per unit energy) used by channels
considered to be MUT sources.
5-95. MUT Meter Constant Units
ENERgy:MUT:CONStant:UNIT(?){ IPWH|IPKWH|
IPMWH|WHPI|KWHPI|MWHPI }
This command specifies the meter constant units (as impulses per unit energy) used by
channels considered to be MUT sources.
IPWH Impulses per Watt-hour
IPKWH Impulses per killoWatt-hour
IPKMH Impulses per MegaWatt-hour
WHIP Watt-hour per impulse
KWHIP killoWatt-hour per impulse
KMHIP MegaWatt-hour per impulse
