Programming Syntax
The following paragraphs describe how to program the power supply via the GP-IB. These instructions concern device-
dependent messages, such as setting output voltage. Interface management messages, such as serial poll, have been
described previously on Page 44, Interface Functions.
Table 3-7 lists each of the device-dependent commands, the range of each parameter sent to the power supply or the
response of the power supply to a query from the controller, and a brief description of each command. Also included is the
number of the paragraph in which each command is described more fully. If no unit is specified where appropriate in data
sent to the power supply, the power supply selects S.I. units (V,A,s).
NOTE Lower-case alpha characters sent to the power supply are treated as upper-case alpha characters.
Numbers Sent to Power Supply. Numbers can be sent to the power supply either with implicit or explicit decimal point
notation, and with or without a scale factor (scientific notation), allowing use with controllers having a wide variety of
output formats.
Numbers written in implicit point notation do not contain a decimal point; for example, 123 for one hundred twenty three.
Numbers written in explicit point notation contain a decimal point, such as 1.23.
In scientific notation the letter ’’E" stands for "10 raised to". For example, 1.23E4 would be read as 1.23 times 10
4
, which
equals 12,300.
