:OUTPut:VECTorsum:MODe <n>
Sets the mode of operation for the vector sum analog output where:
n = 0 >> Output Off
n = 1 >> Output On
:OUTPut:VECTorsum:MODe?
Returns the mode of operation for the vector sum analog output where the
return value represents the following:
0 = Output Off
1 = Output On
:OUTPut#:UNCorrected:SCALing <NRf>
:OUTPut#:CORRected:SCALing <NRf>
:OUTPut:VECTorsum:SCALing <NRf>
Sets the scale value for the selected uncorrected, corrected, or vector sum
analog output where <NRF> is the scale value from 0.0 to 10.0 in 0.1 volt
increments. Setting the value to 0.0 sets the analog output mode to off.
Normally a full-scale level of 3.0 volts is used because it directly
corresponds to the full-scale ranges of the instrument. For instance, if on
the 300 mT range, a reading of -189.3 mT will result in an analog output of
-1.893 volts. If on the 3 kG range, a reading of +2.6 kG will result in an
analog output of +2.6 volts. Some data acquisition systems may require
different analog input ranges. For example, assume such a system cannot
accept signals greater than
±
2.0 volts. In this case you can specify 2.0V
as the full-scale range of the analog output (<NRf> = 2.0).
The relationship between the output voltage and the flux density reading is:
Full Scale Output Voltage / Full Scale Flux Density Range
For example, assume the full scale output voltage has been set to 2.0 volts
and the present range setting is 300 mT. The relationship will be:
2.0 volts / 300 mT = 0.0067 volts / mT
Thus, when the flux density reaches the maximum for the present range,
the analog output voltage will reach a maximum of
±
2.0 volts.
:OUTPut#:UNCorrected:SCALing?
:OUTPut#:CORRected:SCALing?
:OUTPut:VECTorsum:SCALing?
Returns the scaling value for the selected uncorrected, corrected, or vector
sum analog output where the return value represents the scaling factor in
volts.
