(4) Use the PEAK button to set the amplitude of the pulse.
NOTE:
The peak setting is added to the baseline setting.
(5) Use the menu button to scroll through the menu’s to set the slew rate. This is set from the
factory at 100 microseconds.
(6) Use the RUN button to initiate pulse loading. Press RUN a second time to turn pulse off.
(7) Use the SW command to initiate pulse loading.
The slew rate setting is set at the factory for 100 microseconds, but is adjustable through the front
panel menu commands or the IEEE-488 bus.
It is recommended to monitor the current sample output with an oscilloscope to observe the actual
current amplitude and waveform. If waveforms other than square waves are required, this can be
accomplished by programming the loads using an external analog program source (refer to the
Remote Programming
section that follows).
NOTE:
In constant voltage mode the load current is increased by lowering the voltage. Therefore,
in constant voltage pulse mode, the baseline voltage is higher than the peak setting. In
constant resistance pulse mode, the baseline resistance is added in parallel with the peak
resistance.
IEEE-488 Programming
This section covers basic operation only. For detailed information on pulse loading with
the IEEE-488 commands, refer to the
IEEE-488 Commands and Programming
