Discrete | Selects 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, EXTernal, HOLD, |
| IMMediate, or TTLTrgn. |
|
|
Numeric | Commonly used decimal representations of numbers |
| including optional signs, decimal points, and scientific |
| notation. Examples are 123, 123E2, |
| |
| MAXimum, DEFault and INFinity. |
|
|
Optional | Parameters shown within square brackets ([ ]) are optional |
| parameters. (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 TRIGger:LEVel<chan>? |
| [MIN MAX] command. If you send the command without |
| specifying a MINimum or MAXimum parameter, the |
| present TRIGger:LEVel value is returned for the specified |
| channel. If you send the MIN parameter, the command |
| returns the minimum trigger level allowable. If you send the |
| MAX parameter, the command returns the maximum |
| trigger level allowable. Be sure to place a space between |
| the command and the parameter. |

Linking Commands Linking IEEE 488.2 Common Commands with SCPI Commands.
Use only a semicolon between the commands, such as *RST;OUTP:
TTLT4 ON or SAMP:COUNt 25;*WAI.
Linking Multiple SCPI Commands From the Same Subsystem. Use only a semicolon between commands within the same subsystem. For example, to set trigger level, trigger slope and the trigger source which are all set using the TRIGger subsystem, send the SCPI string TRIG:LEVel 1.5; SLOPe NEG; SOURce EXT.
Linking Multiple SCPI Commands of Different Subsystems. Use both a semicolon and a colon between commands of different subsystems. For example, a SAMPle and OUTPut command can be sent in the same SCPI string linked with a semicolon and colon (;:) as SAMP:COUNt 10;:
OUTP:TTLT4 ON
SCPI Command Reference
This section describes the Standard Commands for Programmable Instruments (SCPI) commands for the E1563A and E1564A Digitizers. Commands are listed alphabetically by subsystem and within each subsystem.
