Figure 2-4. Constant Voltage Mode

Immediate Voltage Level

The voltage level can be set at the front panel ( and ENTRY keys) or via the GPIB (VOLT command). If the CV mode is the active mode, the new setting immediately changes the input at a rate determined by the voltage slew setting. If the module is not in the CV mode, the new setting is saved for use when the mode is changed to CV.

Triggered Voltage Level

The voltage level can be preset (stored in the Electronic Load) allowing the input to be updated when a trigger is received instead of immediately as described above. The voltage level can only be preset via the GPIB (VOLT:TRIG) command.

Transient Voltage Level

The transient voltage level can be set at the front panel ( , and ENTRY keys) or via the GPIB

(VOLT:TLEV + command). The module input will switch between the main level and the transient level when transient operation is turned on. The transient voltage level determines the higher voltage level.

Slew Rate

Slew rate determines the rate at which the voltage changes to a new programmed setting. Slew rate can be set at the front

panel (, , and ENTRY keys) or via the GPIB (VOLT:SLEW command). This slew rate remains in effect for the immediate, triggered and transient voltage level changes described above.

There are 12 discrete slew rates that can be programmed for CV Mode slew rate. Any slew-rate value can be sent to a module (there are no upper and lower limits that would cause an error). The module will automatically select one of the 12 rates that is closest to the programmed value. It is important to note that the fastest slew rates cannot be achieved because of bandwidth limitations. The module-specific pages list the usable slew rates.

Transient Operation

Transient operation enables the module to periodically switch between two load levels, as might be required for testing power supplies. A power supply’s regulation and transient characteristics can be evaluated by monitoring the supply’s output voltage under varying combinations of load levels, frequency, duty cycle, and slew rate. Transient operation can be turned

on and off at the front panel ( key) or via the GPIB (TRAN ON and TRAN OFF commands). Before you turn on transient operation, you should set the desired mode of operation as well as all of the parameters associated with transient operation. Transient operation may be used in the CC, CR, or CV modes and can be continuous, pulsed, or toggled. Note that the pulsed or toggled operation cannot be programmed from the front panel.
