Tektronix KEITHLEY 2200 Series, Programming Reference Manual

Page: 21 / 104

Command Groups
This manual lists the power supply commands in two ways. First, it presents
them by functional groups. Then, it lists them alphabetically. The functional
group list starts below. The alphabetical list provides detail on each command.
(See page 2-13.)
The power supply interface conforms to Keithley standard codes and formats
except where noted. The GPIB interface also conforms to IEEE Std 488.2–1987
except where noted. The USB interface also conforms to USB Test and
Measurement Class, Subclass USB488 Speci
fi cation, except where noted.
Arguments are not mentioned in the group command descriptions, but are listed
under the commands in the
Commands Listed in Alphabetical Order section of
this manual. (See page 2-13.)
Status Commands
Status commands let you determine the status of the power supply and control
events.
Several commands and queries are common to all devices on the GPIB or USB
bus. These commands and queries are de
fi ned by IEEE Std. 488.2-1987 and Tek
Standard Codes and Formats 1989, and begin with an asterisk (*) character.
Table 2-5: Status commands
Command Description
*CLS Clear all event registers and queues.
*ESE Set/query standard event status enable register.
*ESR? Return standard event status register.
*IDN? Return identi fi cation information in IEEE 488.2 notation.
*RST Resets to known settings, but does not purge stored settings.
*PSC Set/query power-on status clear.
*SRE Set/query service request enable register.
*STB? Read status byte.
STATus:QUEStionable:INSTrument[:EVENt]?
Return questionable event register.
STATus:QUEStionable:INSTrument:ENABle Set/query questionable enable register. This parameter
determines which bit of the quest event register is set to 1. If a
QUES condition changes, the QUES bit of status byte register
will be set to 1.
STATus:QUESTionable:INSTrument:ISUMmary<x>:[EVENt]? Return questionable event register summary for channel x,
where <x> is 1, 2, or 3.
STATus:QUEStionable:INSTrument:ISUMmary<x>:ENABle Set/query questionable enable register summary for channel x,
where <x> is 1, 2, or 3. This parameter determines which bit of
the quest event register is set to 1. If a QUES condition changes,
the QUES bit of status byte register will be set to x.
