923 milliK manual - issue: 1.10
Example: to apply (add) an offset of 2µV (0.002mV) to voltage measurements made on
channel 1 you can use:
CAL:VOLT:OFFS1 0.002
or
CAL:VOLT:OFFS1 2uV
8.6.29
Command CALibrate:VOLTage:OFFset<channel>?
Format: CALibrate:VOLTage:OFFSet
<channel#>?
Reports the
<offset>
added to voltage measurements made on
<channel>
in volts.
Example: a milliK with a +1µV offset added to voltage measurement made on channel 1 will
respond to
CAL:VOLT:OFFS1?
with: “0.00000100”
8.6.30
Command CALibrate:VOLTage:GAIN
Format: CALibrate:VOLTage:GAIN
<gain>[,<standard>][,<additional info>]
Sets the
<gain>
used for voltage measurements. Gains outside the range 0.98 to 1.02 are
ignored. The optional
<standard>
and
<additional info>
parameters are strings that are
stored in the calibration database file (which can be exported to a USB flash drive: see
section 5.4) to provide information about this calibration. Typically
<standard>
would be
used to identify the serial number of the voltage standard used. The
<additional info>
parameter is provided so store an additional serial number in case two standards are used
(precise low voltages are often realised by using a calibrated reference resistor together with a
current source).
Example: for a milliK that has been found to require a voltage gain of 1.001234 by using a
standard resistor with serial number xyz1956 and a current source with serial number
abc9960, the gain can be set using:
CAL:VOLT:GAIN 1.001234,SN_xyz1956,SN_abc9960
or
CAL:VOLT:GAIN 1.001234
8.6.31
Command CALibrate:VOLTage:GAIN?
Format: CALibrate:VOLTage:GAIN?
Reports the voltage measurement gain.
