*CAL?
Function Executes
zero calibration (zero-level
compensation, the same operation as pressing
CAL (SHIFT+SET)) and queries the result.
Syntax
*CAL?
Example
*CAL? -> 0
Description If the zero-level compensation 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.
Syntax
*CLS
Example
*CLS
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 7.
*ESE
Function
Sets or queries the
standard event enable
register.
Syntax
*ESE {<NRf>}
*ESE?
<NRf>
=
0
to
255
Example
*ESE 251
*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 7-4.
*ESR?
Function
Queries and clears the
standard event register.
Syntax
*ESR?
Example
*ESR? -> 32
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 7-4.
*IDN?
Function
Queries the
instrument model.
Syntax
*IDN?
Example
*IDN? ->
YOKOGAWA,WT310E,123456789A,F1.01
Description • The information is returned in this form:
<manufacture>, <model>, <serial number>,
<firmware version>.
• For details on the model, see “Checking the
Package Contents” in the Getting Started
Guide, IM WT310E-02EN.
*OPC
Function
Sets bit 0 (the OPC bit) of the standard event
register to 1 upon the completion of the specified
overlap command.
Syntax
*OPC
Example
*OPC
Description • This instrument does not have overlap
commands. The OPC bit is always set to 1.
6.17 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.
