4.2 Parameter Definition
The PVS power supply supports communication protocols, which
include standard SCPI commands and a few proprietary commands that
follow the SCPI convention. The SCPI interface enables users to operate
the power supply through a computer or a terminal equipped with IEEE-
488.2 GPIB, RS-232, or USB interface. SCPI IEEE-488.2 also supports
multi-unit control allowing a user to control up to 30 power supplies.
The following table lists all of the numerical parameters.
Boolean value, can be 1 or “ON”, 0 or “OFF”
Integer value, can be zero, positive or negative
integer number
Flexible numerical value, can be zero, positive or
negative float point numeric value
String value, characters enclosed in single or double
quotes
All commands should be ended with the <Rtn> and <NL> and there
should be a space between command and numerical parameter.
4.3 Error/Event List
SCPI interface can offer an error/event list that contains up to 10
errors/events. Users can read the errors/events through the
“SYStem:ERRor?” query command in a first-in first-out manner. Once an
error/event is read, the read process will clear it from the memory. To
