Front-Panel Operation
Flicker 4
4-23
3. External Repetitive
The dip/swell is triggered by a single external low going trigger applied to the
TRIGGER INPUT connector and repeats in free running mode until stopped by a
change to any dip/swell parameter.
An output trigger is provided to control external equipment. This trigger appears on
the TRIGGER OUTPUT connector on the rear of any 6100B or 6101B producing a
dip or swell. The output trigger may be set to occur at the same time as the input
trigger (0 seconds delay), or delayed by a time set in the Trigger Output control field.
When either Free Running or External Repetitive trigger input mode is selected, the
trigger output delay must be less than the total combined dip/swell event time for a
trigger output signal to be generated.
When an External Trigger mode is active, pressing the Force Ext. Trigger softkey
causes a trigger event without an external signal to the rear panel.
4-48. Flicker
Flicker is primarily a voltage phenomenon but is also provided for current outputs in the
6100B. The following sections explain the Flicker Menu.
4-49. Definition
Repetitive (voltage) level variation in the range to cause the physiological phenomenon
of flicker. Flicker severity is described by perception level. This is either perception level
for a short term called P
st
(nominally 10 minutes) or long term called P
lt
. P
st
indications
are valid for voltage at 120 V and 230 V, 50 Hz and 60 Hz. P
st
values, where the
modulating frequency is as tabulated in IEC 61000-4-15 but ΔV/V is some other value,
are valid. In this case, the P
st
value is proportional to the ratio of the tabulated and set
ΔV/V values. P
st
values are never valid for the Current channel.
4-50. Access to Flicker
Use  to navigate to the Waveform Menu and select Edit Flicker from the softkeys.
The Flicker softkeys appear. Figure 4-28 shows the Flicker editing softkeys.

Note
Edition 2 of the IEC 61000-4-15 Flicker standard will be released in 2010
or 2011. The 6100B provides the P
st
and P
inst
values for both the 2003
amendment 1.1; and for Flickermeter development teams; the values under
review by the project team for the Amendment 2.0 standard. The
amendment 2.0 proposal includes some new Flickermeter tests which the
6100B presents as ‘Extended’ functions.
