QUERY COMMANDS

GPIB OPERATION

 

“1/15/98"

 

”Save “”cal_file"" now."

 

'Save “cal_file” now.'

<Arbitrary ASCII>

This notation represents undelimited 7-bit ASCII text. The end of the text must be

 

terminated with the line feed character (0Ah, decimal 10) or a GPIB End of Trans-

 

mission State (EOI), or both. This requirement makes it necessary for <Arbitrary

 

ASCII> text to be transmitted only at the end of a program or response message,

 

that is, at the end of a multiple input or output statement.

 

Example of data represented by <Arbitrary ASCII> notation:

 

Anritsu,2410A,123456,1.0<0A^EOI> The example shows a sample response

 

from the *IDN?, 488.2 common query. In the example, the instrument identifies it-

 

self as an Anritsu 2410A, with serial number 123456, and software version 1.0 in-

 

stalled. Note that decimal 10 (0Ah character) must be sent with the EOI to signal

 

end of transmission.

<Arbitrary Block>

This notation represents data transmitted as 8-bit data bytes (00-FF hex, 0-255

 

decimal, notation is <DAB>). Useful for transmitting large blocks of formatted

 

ASCII or binary data or unformatted binary data. The data stream is immediately

 

preceded by a variable length ASCII header that is encoded with the number of

 

data bytes to be sent. The header always starts with the (#) character.

6-4QUERY COMMANDS Many ML24XXA (native) GPIB commands have an equivalent query command that will return a current value or setting. Query commands and their returned strings are provided with each command where applicable.

A complete listing of valid query commands and returned strings is provided in

Appendix B, Section B-2.
