NSG 3040 EMC test system
8.5.3 Voltage U Var
If no automatic variac or automatic transformer is connected, then the voltage
dip or interrupt will always occur to 0%. Touching the units repetitively it will
change from
%
to
Volts.
If an automatic variac or automatic transformer is connected, then the field
“Voltage Uvar” enables to set the dip voltage level.
If a manual voltage source is connected, then the dips/interrupts level will follow
the manually set voltage at the EUT input, nevertheless this field will be inactive.
8.5.4 Phase
Touching the “Phase” field, it will come up with a red frame to indicate the
selected parameter is ready for change. The value can be modified either with
the red wheel or using the keypad. Touching the “
Synch/Asynch”
button it
will change repetitively. In synch mode the
angle
can be modified either with
the red wheel or using the keypad. Synch mode is only available along with a
automated CDN and if the EUT power (AC) is switched on.
8.5.5 Repetition time
Touching the “Repetition Time” field, it will come up with a red frame to indicate
the selected parameter being ready for change. The value can be modified
either with the red wheel or by using the keypad.
Touching the units repetitively will change from
s, min, cycle, μs
to
ms.
8.5.6 T-Event
Touching the “T-Event” field, it will come up with a red frame to indicate the
selected parameter being ready for change. The value can be modified either
with the red wheel or using the keypad.
Touching the units repetitively will change from
ms, s, cycle,
¹
⁄
10
cycle
or
μs.
8.5.7 Test duration
Touching the “Test Duration” field, it will come up with a red frame to indicate
the selected parameter being ready for change. The value can be modified
either with the red wheel or using the keypad.
Touching the units repetitively will change from
Pulse,
Cont
inuous,
s
to
min.
