Chapter 4 Command Reference
SCPI Conformance InformationSCPI Conformance InformationThe Standard Commands for Programmable Instruments (SCPI) commands used in the 58502A are in conformance with the SCPI Standard Version 1992.0.
Command Syntax Conventions[ ] | An element inside brackets is optional. Note, the |
| brackets are NOT part of the command and |
| should not be sent to the instrument. |
1 2 | Means use either 1 or 2. |
<numeric_value> | Means enter a number. |
POSition | Means you MUST use either all the uppercase |
| letters or the entire word. The lowercase letters |
| are optional. For example, POS and POSITION |
| are both valid. However, POSI is not valid. (Note |
| POSition is used here as an example, but this |
| convention is true for all command keywords.) In |
| other words, the short form of the keywords is |
| shown in uppercase. |
<n> | The notation <n> ending a command keyword |
| indicates a numeric suffix, used to differentiate |
| multiple instances of the same structure. The |
| numeric suffix is applied to both the short and |
| long forms. The valid range for the value n is |
| specified from an enumerated list, for example |
| [123], or from a range, for example [1..3] to in- |
| dicate any of the integers from 1 to 3. |
"TSTamp 1" | When you see quotation marks in the command’s |
| parameter, you must send the quotation marks |
| with the command. |
The Common Commands are general purpose commands that are common to all instruments (as defined in IEEE 488.2). Common Commands are easy to recognize because they all begin with an asterisk or star “*” (for example, *CLS, *IDN?). These commands are generally not related to measurement configuration. They are used for functions like clearing alarms or errors, identification, or setting alarm enables.
