30 Command Reference Chapter 3
Example *ESR?
Sends Standard Event Status Register
query.
*GMC? <
name_string>
Get Macro Query. Returns arbitrary block response data which contains the
command or command sequence defined by name_string. The command sequence
will be prefixed with characters which indicate the number of characters that follow
the prefix.
Example *GMC? ‘ LIST’
Ask for definition of macro from *DMC
example.
If the prefix returned consisted of "#214", the 2 says to expect two
character-counting digits. The 14 says that 14 characters of data follow. Had the
returned macro been shorter, such as #15*EMC?, we would read this as 1 counting
digit indicating 5 data characters.
*IDN?
Identity. Returns the device identity. The response consists of the following four
fields (fields are separated by commas):
• Manufacturer
• Model Number
• Serial Number (returns 0 if not available)
• Firmware Revision (returns 0 if not available)
The *IDN? command returns something similar to the following for the
HP E1411B:
HEWLETT-PACKARD,E1411B,0,B,05.00
Example *IDN?
Queries identity.
*LMC?
Learn Macros Query. Returns a quoted string name for each currently defined
macro. If more than one macro is defined, the quoted strings are separated by
commas (,). If no macro is defined, then a quoted null string ("") is returned.
*LRN?
Learn query command. *LRN? causes the instrument to respond with a string of
SCPI commands which define the instrument’s current state. Your application
program can enter the *LRN? response data into a string variable, later to be sent
back to the instrument to restore that configuration.
Example response from an HP E1326B voltmeter in the power-on state:
