B.2 NUMERICAL VALUES AND DATA CONVENTIONS
The following conventions are used throughout this Appendix.
< > Items in these brackets are parameter abbreviations. Parameters may be numbers or text
Simple numbers (without a decimal point) from 0 - 255. Examples: 156, 0 or 1
Numeric Values with or without a decimal point. Examples: 0.0156, 15.6, 156 or 1.56E+3 (scientific
notation: digits with decimal point and exponent)
Text data. For example, operating modes: CURRent, VOLTage, POWer, RESistance, CONDuctance,
SHORt
Boolean Data. Examples: 0, 1, OFF or ON. NOTE: If a command expecting a boolean argument is
sent with no argument, the argument is assumed to be 0 (e.g., INPut and INPut 0 are identical).
[ ] Optional keywords are shown in square brackets. For example [SOURce:]INPut:[STATe]
means SOURce and STATe: may be omitted thus the command is reduced to INP .
B.3 DIAGnostic:RESet COMMAND
DIAG:RES
Syntax: Short Form: DIAG:RES Long Form: DIAGnostic:RESet
Description: Allows user to change operation of *RST from SCPI to PPM mode. PPM mode is provided to pro-
vide backward compatibility with earlier versions of EL Load Firmware.
*RST in PPM mode causes a full reboot of the EL load. During the reboot, data is sent by the EL load
to the host interface (similar to that shown in Figure 3-2). The data must be received in order for the EL
load to function normally (this can be as many as 50,000 characters, taking minutes to complete). Wait
at least 200 milliseconds after all data is received before sending any commands to the load. *RST
sets the voltage protection level to 600, Current protection to 600 (or the total current of the system
when slaves are connected), and power protection to 5000 (or 600 multiplied by the total current of
system when slaves are connected). *RST also resets damping to the factory default levels of 5 and 3,
sets SYST:COMM:ECHO to on (see PAR. B.70), and sets SYST:REPLY to off; it does not affect any
set points.
B.4 DIAGnostic:TREE:DISPlay COMMAND
DIAG:TREE:DISP
Syntax: Short Form: DIAG:TREE:DISP Long Form: DIAGnostic:TREE:DISPlay
Description: Produces text file showing the SCPI command set accessible to the user. The text file is
arranged in columns and can be imported into a spreadsheet application such as Excel for easy view-
ing. The column separator is determined by DIAG:TREE:SEP command
B.5 DIAGnostic:TREE:SEParator COMMAND
DIAG:TREE:SEP
Syntax: Short Form: DIAG:TREE:SEP Long Form: DIAGnostic:TREE:SEParator
where defines the column separator
Description: Defines the column separator used when producing a text file of the command set using
DIAG:TREE:DISP command.
B.6 DIAGnostic:TREE:SEParator? QUERY
DIAG:TREE:SEP?
Syntax: Short Form: DIAG:TREE:SEP? Long Form: DIAGnostic:TREE:SEParator?
Returns defines the column separator
Description: Returns the number corresponding to the selected column separator when producing a text
file of the command set using DIAG:TREE:DISP command.
