126 Agilent E1441A SCPI Command Reference
Chapter 3
*IDN?
*IDN? returns identification information for the Agilent E1441A. The response
consists of four fields:
HEWLETT-PACKARD,E1441A,0,A.01.00-A.01.09
The first two fields identify this instrument as model number Agilent E1441A
manufactured by Agilent Technologies (Agilent spun off of HP in November 1999;
firmware will still say Hewlett-Packard). The third field is 0 since the serial number
of the Agilent E1441A is unknown to the firmware. The last field indicates the
revision level of the inguard-outguard firmware.
Note The firmware revision field will change whenever the firmware is revised.
A.01.00-A.01.00 is the initial revision. The first two digits indicate the
major revision number, and increment when functional changes are made.
The last two digits indicate the functional fix level.
