If warm up is specified as energy or pulse periods, it is important to ensure the duration
specified is equivalent to at least 2 seconds to permit adequate settling of the main output.
If duration is specified as energy from MUT or Reference channels, then the system will
accumulate at least this amount of energy on the specified channel(s) to the next whole
pulse period. Only whole pulse periods are allowed. One pulse period is the duration
between two pulses from a MUT or Reference. If both the warm-up and test duration are
specified as pulses from the same source, the last pulse of the warm-up is taken to be the
first pulse of the test. If time is used to specify the test duration, then it should be
adequate to cover at least one pulse period, otherwise there will be no meaningful
measurement.
If desired, a Gate Output signal may be enabled. This will be active for the duration of
the actual measured test (not the warm-up and settling period). The gate signal can
consist of a level of the required duration, or as a start and end pulse, and may be active
high or low.
In the Counted/Timed mode, the MUT and reference meter dials may advance more than
the amount measured by the 6100B Energy Option. This is normal, and represents
settling and warm-up times included in the test. The actual test duration and count to
achieve the displayed result is accurate.
4-76. Gated Mode
In Gated Mode, the Energy Gate connector (on the rear panel) becomes an input. When
 is pressed, power is applied to the MUT. Energy counts and error calculations will
take place, but until the Gate signal becomes active, it is considered a warm-up period.
When the Gate signal activates, the counts reset and the true test starts. The test
terminates and the 6100B output is turned off when the gate becomes inactive.
If the period between the first application of power to the MUT and the gate becoming
active is more than 2 seconds, the Gated mode accuracy is the same as for the
Counted/Timed mode. See Figure 4-43.
