Model 6220/6221 User’s Manual DC Current Source Operation 3-15
Return to Section 3 topics
Remote programming – source output commands
Table 3-2 lists the commands to configure and control the DC output. A program-
ming example to output DC current is also provided.
1. To select a fixed source range, specify the current output value that is going to
be sourced. The Model 622x will go to the lowest range that can source that
value. For example, If you are going to source 25mA, let <n> = 25e-3. The
100mA range will be selected.
2. Selecting a fixed source range disables autorange.
3. The output must be off in order change the output response. Sending this
command while the output is on will generate error -220 Execution Error.
4. OUTP OFF turns the output off, but does change the set output level.
SOUR:CLE sets the output level to zero and then turns the output off.
