Fig. 2-7 Pulsed Transient Operation
2.4.3
Toggled Transient Mode
The trigger function is required for toggled transient operation. When there is no trigger occurs,
the load remains at a transient level. After a trigger has been received, a toggle operation will be
executed, and another transient level will be reached after the duration of rising edge or falling edge.
The
associated
parameters such as transient low level (LevelL), transient high level (LevelH), time for
rising edge (TimeR), time for falling edge (TimeF), and toggled transient mode can be set through
transient operation menu or via remote command (CURRent:LOW <NRf+>, CURRent:HIGH
<NRf+>, VOLTage:LOW <NRf+>, VOLTage:HIGH <NRf+>, RESistance:LOW <NRf+>,
RESistance:HIGH <NRf+>, TRANsient:RTIMe <NRf+>, TRANsient:FTIMe <NRf+>,
TRANsient:MODE TOGGle, TRANsient ON | OFF).
The trigger can be an external trigger signal received via the TRIG input on the front panel,
pressing the
key +
key, or the remote command ( *TRG/TRIGger).
For example: assume that the CCH range is active, and the input is in OFF status, then the
transient parameters should be set as follows:
Press
key to enter into transient operation;
Press
key to open transient operation menu;
Set the following parameters in transient operation menu:
LevelL: 5.000A
LevelH : 10.000A
TimeL : 0.50ms
TimeH : 0.50ms
TimeR : 0.10ms
TimeF : 0.20ms
Mode : Togg
Then press
key to turn on the input;
Send the command to the load:INIT
Or via remote command to set:
