Dynamic Waveform Definition:
There are six parameters to generate a dynamic waveform or pulse waveform: High/Low load
levels, Rise/Fall slew rates, and T
HIGH
/T
LOW
durations. The SLM-series DC electronic load will
sink current from the power source, proportional to the dynamic waveform. The dynamic
waveform definition is shown in Figure 1-10.
The formula to define the period of dynamic waveform is:
Dynamic frequency = 1 /(T

The load current level and load status can be set by any of three ways:
• on the front panel of each load module,
• through the mainframe store/recall memory, or
• with GPIB/RS-232 commands
The load input voltage and load current can be read back to the computer through GPIB or RS-232 bus.
(See the SLM Mainframe Operation Manual for a description of the mainframe store/recall and
GPIB/RS-232 remote operation).
