Comments • Executable when initiated: No
• Coupled Command: No
• Before executing this command, both channels must be set to the single-ended
setting and 1.0235 volt range. This can be accomplished by executing either
*RST or the combination of CONF:ARR:VOLT (1),1.0,(@1) with
CONF2:ARR:VOLT (1),1.0,(@2).
• This setting was calibrated before the HP E1429 left the factory. Under normal
conditions, it is not necessary to execute this command again. The symptom of
needing this calibration is that the fastest sample rate will appear to be 10 MHz
instead of 20 MHz, especially at higher ambient operating temperatures (such as
50 or 60 degrees C).
• Both channels are calibrated with a single call to this command, so a single call
will be sufficient to calibrate.
• If CALibration:STORe:AUTO is ON, then the new settings will be stored to
non-volatile calibration ram. Calibration security must also be turned off for the
new constants to be permanently stored in non-volatile calibration ram.
• CALibration:COUNt will be incremented with this command when the values are
stored to non-volatile calibration RAM.
• Related commands: CALibration:SECure:STATe, CALibration:STORe:AUTO,
CALibration:STORe
• *RST Condition: unaffected

:GAIN
CALibration[<chan >]:GAIN [<readings >[,<period >[,<flag >]]] performs a
calibration for gain using the specified number of readings and sample rate. The
CALibration:VALue voltage specified is used as the full scale value to calibrate to,
and must be between 85.0 and 99.5 percent of the full scale reading for the current
configuration. The 99.5 percent upper limit is to insure that noise will not cause
erroneous full scale (overload) readings. A linearity calibration is also done on the
1V measurement range with the single ended port (0 or 2). This linearity calibration
may be disabled by setting the flag parameter to OFF. Omitting the optional flag
parameter will cause linearity to be performed.
