⚫ Discrete parameter
Discrete Parameter are used for settings with limited number of programming
values (such as IMMediate, EXTernal or BUS). They can use short and long
format like key words of commands. They may be expressed in both upper and
lower case. The query response always returns uppercase Parameter in short
format. The following commands require discrete Parameter in voltage unit:
[SOURce[1|2]:]VOLTage:UNIT {VPP|VRMS|DBM}
⚫ Boolean parameter
Boolean Parameter refer to true or false binary conditions. In case of false
conditions, the instrument will accept "OFF" or "0". In case of true conditions,
the instrument will accept "ON" or "1". In query of Boolean settings, the
instrument will always return "0" or "1". Boolean Parameter are required by the
following commands:
DISPlay {OFF|0|ON|1}
⚫ ASCII string Parameter
String Parameter may actually include all ASCII character sets. Character
strings must start and end with paired quotation marks; and single quotation
marks or double quotation marks are both allowed. Quotation mark separators
may also act as one part of a string, they can be typed twice without any
character added between them. String parameter is used in the following
command:
DISPlay:TEXT <quoted string>
For example, the following commands display message of "WAITING..."
(without quotation marks) on the front panel of the instrument.
DISP:TEXT "WAITING..."
Single quotation marks may also be used to display the same message.
DISP:TEXT 'WAITING...'
1.8 Remote Interface Communication
1.8.1 Communication Modules Intruduction
The DB9 interface connector on the rear panel of the load
(IT8511+/IT8511A+/IT8512+/IT8512A+/IT8512B+/IT8512C+/IT8512H+/IT8513
A+/IT8513C+) is TTL voltage level, which needs to be connected to the serial
port of the PC through level conversion. The optional communication module is
IT-E121/IT-E121A/IT-E122/IT-E123.
The IT8513B+/IT8514B+/IT8514C+/IT8516C+ load includes standard RS232
and USB communication interface.
Do not connect the electronic load (IT8511+/IT8511A+/IT8512+/IT8512A+/
IT8512B+/IT8512C+/IT8512H+/IT8513A+/IT8513C+) with a standard RS232
cable, which may result in damage to the instrument.
IT-E121 Communication Module
The DB9 interface connector on the rear panel of the DC load is TTL voltage
level; you can use the communication module IT-E121 and a standard RS232
extension cable to connect the DB9 interface connector of the DC load and the
RS-232 interface connector of computer for the communication.
