M9B-HFS OPERATION
M9B-HFS INTERFACE
3-8
Release 1.0 (97/10)
ILO
In response to this command, the power supply sends a programmed current value to the
output terminal. This value is at the low end of the power supply’s current range and is
read by an external device connected as part of the calibration procedure. Refer to this
value as ILO and record it to use as input with the IDATA command. Set CMODE ON
before using this command. See also the calibration procedures in Section
4.
IMAX <current>
Parameter:
current
Sets an upper soft limit on the supply’s programmed output current. If the soft limit is
exceeded, or if the soft limit value is lower than the present output current setting, the
supply will ignore the command, turn on the ERR LED, and set the ERR bit in the status
registers.
Range:
0 to model maximum output current (IMAX)
Initial value:
IMAX
IMAX?
Asks for the supply’s soft current limit setting.
Response:
IMAX <current>
IOUT?
Measures the supply’s actual current output using the built
-in current readback circuitry.
Response:
IOUT <current>
IRDAT<Ilo>,
<Ihi>
Parameters:
<Ilo>, <Ihi>
Calculates and records the slope and offset for readback voltage using IRLO and IRHI
data. Set CMODE ON before using this command. See also the calibration procedures in
Section 4.
IRHI
The power supply outputs a current value to an external device connected as part of the
calibration procedure and records a current readback value internally. These values are at
the high end of the programmed current range. Refer to the output value as IRHI and
record it to use as input with the IRDAT command. Set CMODE ON before using this
command. See also the calibration procedures in Section
4.
IRLO
The power supply outputs a current value to an external device connected as part of the
calibration procedure and records a current readback value internally. These values are at
the low end of the programmed current range. Refer to the output value as IRLO and
record it to use as input with the IRDAT command. Set CMODE ON before using this
command. See also the calibration procedures in Section
4.
ISET <current>
Parameter:
current
Sets the power supply’s output current in amps (default) or in milliamps. This
programmed current is the actual output in CC mode or the current limit in CV mode.
Range:
0 to model maximum output current (IMAX)
Initial value:
0 amps
