You can see the VOLT setting being incremented or decremented each time you press the applicable Input key. The values are entered automatically (you don’t press the Enter key). Remember if the CV mode is active, the incremented or decremented values will immediately change the actual input.

2.Set Slew Rate - There are 12 discrete steps within the voltage slew range. The Multiple Electronic Load automatically selects one of the 12 slew rates that is closest to the programmed value.

Note

Because of bandwidth limitations only 9 slew rate steps can be achieved. Although CV slew rates #10

 

through #12 may be programmed, they are not implemented.

 

 

a.First press (blue shift key) and note that the Shift annunciator goes on. Now press (shifted Tran Level key) to determine the present slew setting. Note that the display indicates "V:SLW" and the maximum slew rate.

b.Set the slew rate to 0.5 V/us by pressing

c.Press and again and note that the display indicates "V:SLW 0.5000".

3.Set Transient Level - The transient voltage level is meaningful only if transient operation (describe later) is turned on. The transient voltage level must be set to a higher value than the main voltage level in order for transient operation to take place.

a.Press and note that the display indicates "V:TLV" and the maximum voltage value.

b.Set the transient voltage level to 30 volts by pressing

c.Press again and note that the display indicates "V:TLV 30.000".

You can use the Input Entry keys to increment and decrement the transient voltage level. Operation is similar to that described above for the main voltage level.

Transient Operation

Transient operation can be used in the CC, CR, or CV mode. It causes the selected channel (module) to switch between two load levels. Continuous transient operation can be programmed from the front panel or remotely via the GPIB. Pulsed and toggled transient operation can only be programmed remotely via the GPIB.

In continuous transient operation, a repetitive pulse train switches between two load levels. Transient operation is turned on and off at the front panel using the Tran on/off key. Before you turn on transient operation, you should set the desired mode of operation as well as all of the values associated with transient operation.

The two load levels in transient operation are the main and transient levels previously described for CC, CR, and CV. The rate at which the level changes is determined by the associated slew rate setting.

In addition to the mode dependent parameters mentioned above, the frequency and the duty cycle of the continuous pulse train are programmable.

The following example illustrates how to program transient operation in the CC mode.
