SCPI Introduction

MIN and MAX are the minimum and maximum finite number. Within the range

of the parameter definition, DEF is the default of the parameter.

⚫ 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...'

– <SPD>: string program data. String parameters enclosed in single or

double quotes.

– <CPD>: character program data.

1.7 Remote Interface Connection

as standard: USB, LAN and CAN, and two optional interfaces: RS232 and GPIB.

Users can choose any one to realize communication with the computer. For

detailed introduction of remote interface connection, please refer to the content in
