A floating point number of volts
between 0 and 10, or the word: off.
Use with do-loops:
When a HeaterVoltage variable is used as the dependent variable of a
do-loop, the associated loop increment is
specified as a Double constant.
Examples:
The following example first sets the desired sensor voltage of
the cryostat heater of receiver 0 to 3.03 volts, then
subsequently turns the heater off.
heater rx0, cryo, 3.03
...
heater rx0, cryo, off
Context:
The heater command sets the
temperatures of three small heaters per receiver, one in
the receiver cryostat and two unassigned heaters outside the
cryostat. The heater temperatures are controlled via feedback
loops that maintain the output of a neighboring thermistor or
thermocouple sensor at a given fixed voltage. The HeaterVoltage
argument of the heater command thus indirectly sets the target
temperature of these heaters.
