HP_ps
Purpose:
-
Communicate with a Hewlett Packard programmable power supply.
Enter:
-
HP_ps <voltage_limit> <current_limit> &
Where:
-
voltage_limit
Specify the initial voltage limit to set before any other commands are accepted.
current_limit
Specify the initial current limit to set before any other commands are accepted.
Example:
-
HP_ps 14 20 &
Launch the program and set voltage limit to 14.0 volts and current limit to 20 amps,
Notes:
-
Below is a summary of commands which can be sent to the device, what they return and the variables associated with each field.
Command line examples:
HP_set <action> [value] &
HP_set v 12 – set voltage level to 12.0 volts
value 12.0 stored in “HP_voltage_set”HP_set vover 20 – set voltage limit to 20.0 volts
value 20.0 stored in “HP_set_overvolt”HP_set maxi 30 – set current limit to 30.0 amps
value 30.0 stored in “HP_set_max_i”HP_set read_vstpt – read voltage setpoint
prints value and stores in “HP_read_set_v”HP_set read_vover – read voltage limit
prints value and stores in “HP_read_over_v”HP_set read_maxi – read current limit
prints value and stores in “HP_read_max_i”HP_set reset – reset PS to default values
HP_set enable – enable output
stores value in “HP_outp”HP_set disable – disable output
stores value in “HP_outp”HP_set read_enable – read the enable/disable state
prints value and stores value in “HP_outp”
