2-11 Analog programming BNC input
The BNC connector on the rear panel connects .
The 0 to 10V Analog signal can program the 0 to full scale input range in the CC mode ( 0 to
24A range when load current setting is less than 24A, or 0 to 240A range when load current
setting is higher than 24A) or in the CP mode (0 to 2400W). The analog programming signal
can act alone or it can be summed with the programmed value via GPIB, RS-232, or the front
panel. Fig 3-3 shows the analog programming signal (4 Vac, 500Hz) is summed with the 96A
programmed setting in CC mode of 33501 Load module.
