Ramp Configuration Commands and Queries
•
FIELD:MAGnet?
Returns the calculated field in kilogauss or tesla, per the selected field
units. This query requires that a coil constant be defined; otherwise, an
error is generated. The field is calculated by multiplying the measured
magnet current by the coil constant. If the magnet is in persistent mode,
the command returns the field that was present when persistent mode was
entered.
•
INDuctance?
Returns the measured magnet inductance in henries. Note that the
magnet must be ramping when this command is executed. Refer to section
3.10.2.5 on page 53.
•
CONFigure:RAMPDown:ENABle {0|1}
Enables the external rampdown function. “1” enables while “0” disables.
“0” is the default value.
•
RAMPDown:ENABle?
Queries whether the external rampdown function is enabled. Returns “1”
for enabled while “0” for disabled. “0” is the default value.
•
CONFigure:RAMPDown:RATE:SEGments <
# segments
>
Sets the number of external rampdown segments.
•
RAMPDown:RATE:SEGments?
Returns the number of external rampdown segments.
•
CONFigure:RAMPDown:RATE:CURRent <
segment
>,<
rate (A/s, A/
min)
>, <
upper bound (A)
>
Sets the external rampdown rate for the specified segment (values of 1
through the defined number of rampdown segments are valid) in units of
A/sec or A/min (per the selected rampdown rate units), and defines the
current upper bound for that segment in amperes.
•
RAMPDown:RATE:CURRent: <
segment
>?
Returns the external rampdown rate setting for the specified segment
(values of 1 through the defined number of rampdown segments are valid)
in units of A/sec or A/min (per the selected rampdown rate units) and the
current upper bound for that range in amperes. The two return values are
separated by a comma. For example:
RAMPDown:RATE:CURRENT:1?
0.1000,50.0000
