4.4.11 Output Voltage Programming by external voltage
External control connector
Fig. 4-7 shows the set-up for external voltage programming of the output voltage. A voltage source
variable from 0 to 4V, programs the output voltage proportionally from zero to full scale. The static load
current on the programming source is less than 2uA. The source resistance should be less than
10Kohm to avoid degradation of offset and drift specifications. When external voltage is used for
programming the front panel and the computer control (via the serial communication) are disabled.
Note: Full scale is 105% of the rated output voltage.
