Common Command Group - YOKOGAWA WT1800 User Manual

5.23 Common Command Group

The commands in this group are defined in IEEE 488.2-1992 and are independent from the instrument's individual
functions.There are no front panel keys that correspond to the commands in this group.
*CAL?
Function Executes zero calibration (zero-level
compensation, the same operation as pressing
CAL—SHIFT+SINGLE) and queries the result.
*CAL?
Syntax
*CAL? -> 0
Example
Description If the calibration ends normally, 0 is returned. If
an error is detected, 1 is returned.
*CLS
Function Clears the standard event register, extended
event register, and error queue.
*CLS
Syntax
*CLS
Example
Description • If the *CLS command is located immediately
after the program message terminator, the
output queue is also cleared.
• For information about each register and queue,
see chapter 6.
*ESE
Function Sets or queries the standard event enable
register.
*ESE {<NRf>}
Syntax
*ESE?
<NRf> = 0 to 255
*ESE 251
Example
*ESE? -> 251
Description • Specify the value as a sum of the values of
each bit in decimal format.
• For example, specifying *ESE 251 will cause
the standard enable register to be set to
11111011.In this case, bit 2 of the standard
event register is disabled. This means that bit 5
(ESB) of the status byte register is not set to 1,
even if a query error occurs.
• The default value is *ESE 0 (all bits disabled).
• A query using *ESE? will not clear the contents
of the standard event enable register.
• For information about the standard event
enable register, see page 6-4.
5-102
*ESR?
Function Queries and clears the standard event register.
*ESR?
Syntax
*ESR? -> 32
Example
Description • A sum of the values of each bit is returned in
decimal format.
• When an SRQ is sent, you can check what
types of events have occurred.
• For example, if a value of 32 is returned, this
indicates that the standard event register is
set to 00100000.This means that the SRQ
occurred due to a command syntax error.
• A query using *ESR? will clear the contents of
the standard event register.
• For information about the standard event
register, see page 6-4.
*IDN?
Function Queries the instrument model.
*IDN?
Syntax
*IDN? ->
Example
YOKOGAWA,WT1806-06,123456789,F1.01
Description • The information is returned in this form:
<Manufacturer>, <Model>, <Serial no.>,
<Firmware version>.
• <Model> is returned in the following format:
"six-digit model code—two-digit element
structure."For details on the model code and
element structure, see "Checking the Package
Contents" in the getting started guide, IM
WT1801-03EN.
*OPC
Function Sets bit 0 (the OPC bit) of the standard event
register to 1 upon the completion of the specified
overlap command.
*OPC
Syntax
*OPC
Example
Description • For information about how to synchronize a
program using *OPC, see page 4-8.
• The COMMunicate:OPSE command is used to
specify the overlap command.
• If *OPC is not the last command of the
message, its operation is not guaranteed.
