4.3 REMOTE PROTOCOLS

This section describes the complete command set for remote communication via RS232

interface. It specifies the syntax of each command, and all of them will explicitly take

the unit to REM mode of operation.

TERMINATION CHARACTER

All commands, transmitted between the instrument and the computer, are terminated

with a Linefeed (LF) character (“\n” or 0x0A). Carriage Return (CR) character (“\r” or

0x0D) can also be used to terminate commands sent to the instrument, but all returned

strings from query strings will terminate with LF character.

SCPI Commands

Numerical data Formats

<NR1> Digits with an implied decimal point assumed at the right of the least-significant

digit. Example: 273

<NR2> Digits with an explicit decimal point. Example: .0273

<NR3> Digits with an explicit decimal point and an exponent. Example: 2.73E+2

<Bool> Boolean Data. Example: 0|1 or OFF|ON (0 = OFF; 1 = ON)

<Nrf> Extended format that includes <NR1>, <NR2>, and <NR3>. Examples: 273273.

2.73E2

<Nrf+> Expanded decimal format that includes <NRf> and MINMAX. Examples: 273

73.2 .73E2 MAX. MIN and MAX are the minimum and maximum limit values that are

implicit in the range specification for the parameter.
