Agilent Technologies 75000 SERIES B # non-zero digit digits data bytes, Indefinite Length Block

(e.g., 123, 123E2, -123, -1.23E2, .123, 1.23E -2, 1.23000E - 01). Special cases include MIN, MAX, and INFinity. The Comments section within the Command Reference will state whether a numeric parameter can also be specified in hex, octal, and/or binary. # H7B, # Q173, # B1111011

•Boolean parameters represent a single binary condition that is either true or false (e.g., ON, OFF, 1, 0). Any non-zero value is considered true.

Discreet parameters select from a finite number of values. These parameters use mnemonics to represent each valid setting. An example is the TRIGger:SOURce < source> command where source can be BUS, EXT, HOLD, or IMM.

•Arbitraty Block Program Data parameters are used to transfer blocks of data in the form of bytes. The block of data bytes is preceded by a preamble which indicates either 1) the number of data bytes which follow, or 2) that the following data block will be terminated upon receipt of a New Line message with the EOI signal true. The syntax is:

Definite Length Block

#< non-zero digit> < digit(s)> < data byte(s)>

Where the value of < non-zero digit> equals the number of

<digit(s)> . The value of < digit(s)> taken as a decimal integer indicates the number of < data byte(s)> in the block.

Indefinite Length Block

# 0< data byte(s)> < NL^ END>

Examples of sending 4 data bytes:

#14< byte> < byte> < byte> < byte>

#3004< byte> < byte> < byte> < byte>

#0< byte> < byte> < byte> < byte> < NL^ END>

Optional Parameters. Parameters shown within square brackets ([ ] ) are optional parameters. (Note that the brackets are not part of the command, and are not sent to the instrument.) If you do not specify a value for an optional parameter, the instrument chooses a default value. For example, consider the ARM:COUNt? [< MIN MAX> ] command. If you send the command without specifying a parameter, the present ARM:COUNt value is returned. If you send the MIN parameter, the command returns the minimum count available. If you send the MAX parameter, the command returns the maximum count available. Be sure to place a space between the command and the parameter.

Linking Commands Linking IEEE 488.2 Common Commands with SCPI Commands. Use a

semicolon between the commands. For example:

*RST;OUTP ON or TRIG:SOUR HOLD;*TRG

Linking Multiple SCPI commands. Use both a semicolon and a colon between the commands. For example:

ARM:COUN 1;:TRIG:SOUR EXT
