RDGI?
Current Output Reading Query
Input: RDGI? [term]
Returned: <current> [term]
Format: ± nn.nnnn
<current> Actual measured output current.
RDGRV?
Remote Voltage Sense Reading Query
Input: RDGRV? [term]
Returned: <voltage> [term]
Format: ± n.nnnn
<voltage> Actual voltage measured at the remote voltage sense leads.
RDGV?
Output Voltage Reading Query
Input: RDGV? [term]
Returned: <voltage> [term]
Format: ± n.nnnn
<voltage> Actual output voltage measured at the power supply terminals.
RSEG
Ramp Segments Enable Command
Input: RSEG <enable> [term]
Format: n [term]
<enable>
Specifies if ramp segments are to be used: 0 = Disabled, 1 = Enabled.
Remarks: Ramp segments are used to change the output current ramp rate based on the output current. Ramp
segments need to be setup first using the RSEGS command.
RSEG?
Ramp Segments Enable Query
Input: RSEG? [term]
Returned: <enable> [term]
Format: n (Refer to command for description)
RSEGS
Ramp Segments Parameters Command
Input: RSEGS <segment>, <current>, <rate> [term]
Format: n, +nn.nnnn, +n.nnnn [term]
<segment>
Specifies the ramp segment to be modified: 1 – 5.
<current> Specifies the upper output current setting that will use this segment:
0.0000 –
+ 60.1000A.
<rate> Specifies the rate at which the current will ramp at when the output current is in this
segment: 0.0001 – 99.999 A/s.
Remarks: Ramp segments are used to change the output current ramp rate based on the output current. The ramp
segment feature needs to be turned on using the RSEG command.
RSEGS?
Ramp Segments Parameters Query
Input: RSEGS? <segment>[term]
Returned: <current>, <rate> [term]
Format: +nn.nnnn, +n.nnnn (Refer to command for description)
