SYSTem:IDENtify {DEFault|HP34401A}
SYSTem:IDENtify?
Selects the manufacturer and model number returned by *IDN?. The serial number and revision information are
unaffected, and this command does not change instrument operation. You can use this command to avoid changing
existing test systems where the manufacturer and model number are checked and expected to indicate a 34401A.
Parameter Typical Return
{DEFault|HP34401A} DEF or HP34401A
Select a *IDN? response compatible with the 34401A:
SYST:IDEN HP34401A
*IDN?
Typical Response: HEWLETT-PACKARD,34401A,...
l DEFault selects the default response:
"Agilent Technologies,34460A, ..."
"Agilent Technologies,34461A, ..."
l HP34401A selects a response compatible with the 34401A:
"HEWLETT-PACKARD,34401A, ..."
l This setting is non-volatile; it is not changed by power cycling, a Factory Reset (*RST), or an Instrument Preset
(SYSTem:PRESet).
SYSTem:LABel "<string>"
SYSTem:LABel?
Places a message in a large font on the bottom half of the instrument's front-panel display.
Parameter Typical Return
A quoted string of up to 40 characters. You can use letters (A-Z), numbers (0-9) and special
characters such as @, %, *, and so forth.
Default ""
"Battery DCI"
Set the message to be displayed on the screen:
SYST:LAB "Battery DCI"
l If you enter a string longer than 40 characters, the instrument truncates the string after the first 40 characters."
l The font size changes based on the length of the message and whatever other information is shown on the
display.
l To turn off the message, send SYST:LAB "" to change the label to a null string. This also removes the label area
from the screen.
l The value of this parameter is not affected by *RST or SYSTem:PRESet.
SYSTem:PRESet
This command is nearly identical to *RST. The difference is that *RST resets the instrument for SCPI operation, and
SYSTem:PRESet resets the instrument for front-panel operation. As a result, *RST turns the histogram and statistics
off, and SYSTem:PRESet turns them on (CALC:TRAN:HIST:STAT ON).
