SYSTem:IDENtify {DEFault|AT34460A|AT34461A|AT34410A|AT34411A|HP34401A}
SYSTem:IDENtify?
Selects the manufacturer and model number returned by *IDN?. The serial number and revision inform-
ation are unaffected, and this command does not change instrument operation. Use to avoid changing
existing test system code where the manufacturer/model number are verified.

Select a *IDN? response compatible with the 34401A:
SYST:IDEN HP34401A
*IDN?
Typical Response: HEWLETT-PACKARD,34401A,...
The allowable parameters for each DMM model are:
l
34460A - valid parameters: DEFault, AT34460A, HP34401A
l
34461A - valid parameters: DEFault, AT34461A, HP34401A
l
34465A - valid parameters: DEFault, AT34410A, AT34411A
l
34470A - valid parameters: DEFault, AT34410A, AT34411A

DEFault returns "Keysight Technologies" followed by the actual instrument model number:
l
"Keysight Technologies,34460A, ..."
l
"Keysight Technologies,34461A, ..."
l
"Keysight Technologies,34465A, ..."
l
"Keysight Technologies,34470A, ..."
l
If you have an older Agilent 34460A or 34461A and upgrade to the new (Keysight) firmware, your
l
instrument continues to respond with the manufacturer name "Agilent", not "Keysight" until you set
the front panel SCPI ID to 34460A or 34461A, send the
erences. After doing this, the instrument responds with "Keysight" as the manufacturer.
This setting is non-volatile; it is not changed by power cycling, a Factory Reset (*RST), or an Instru-
l
ment Preset (SYSTem:PRESet).
Important: In order to update the instrument firmware from remote, the model number in the
l
response must match the actual instrument model number. If you have changed the instrument's
*IDN?
response to another instrument, when attempting to update the firmware from remote, you will
see this error: The instrument is not supported by this firmware file. To update the firmware, either
update using the front panel procedure or, from remote, use
match the actual model number, update the firmware, and then use
*IDN?
response to the other model number.
