Tracking Operation
This power supply provides tracking outputs. In the track mode, two voltages of the
output1 and the output2 supplies track each other within the voltage programming
accuracy as described on page 163 in chapter 8 for convenience in varying the
symmetrical voltages needed by operational amplifiers and other circuits using
balanced two outputs. The track mode is always off state when power has been off or
after a remote interface reset.
• Front-panel operation:
1 Set either the output1 or the output2 supply to the desired voltage.
2 Enable the track mode.
Hold down key until the
Track
annunciator turns on. For example, when the
track mode is first enabled with the output1 selected, the output2 supply will be set
to the same voltage level as the output1 supply. Once enabled, any change of the
voltage level in either the output1 or the output2 supply will be reflected in other
supply. The current limit is independently set for each of the output1 or the output2
supply and is not affected by the track mode.
3 Exit the track mode.
The
Track
annunciator turns off.
N o t e The tracking accuracy is dependent upon the voltage programming accuracy of each
output. See ‘‘Performance Specifications’’ for more information starting on page 163
in chapter 8.
