4.2.4 Analog Output Commands
This paragraph provides a detailed description of each Analog Output Command. The commands
allow the user to control the output of the analog output over the interface.
ANOD
Set Analog Output Default.
Input:
ANOD 0
or
ANOD 1
Returned:
Nothing
Remarks:
Set default off with ANOD 0 and on with ANOD 1. Default on gives 10 mV/K
(10 V analog output for 1000 K and 0 V for 0 K).
ANOD?
Analog Default Query.
Input:
ANOD?
Returned:
0
or
1
Remarks:
1 indicates the default analog output scaling is in effect. The default scaling is
10 mV/K (10 V analog output for 1000 K and 0 V for 0 K).
ANOH
Set Analog Output Maximum (High).
Input:
ANOH XXX.X
Returned:
Nothing
Remarks:
Set the analog output maximum (high), where XXX.X is between 0 and 999.9.
Example:
ANOH 500[term]
instructs the Model 321 to make the 10 V output correspond
to 500 K.
ANOH?
Analog Output Maximum (High) Query.
Input:
ANOH?
Returned:
XXX.X
Remarks:
Returns the current value of the temperature in kelvin which gives 10 V output.
ANOL
Set Analog Output Minimum (Low).
Input:
ANOL XXX.X
Returned:
Nothing
Remarks:
Set the analog output minimum (low), where XXX.X is between 0 and 999.9.
Example:
ANOL 100[term]
instructs the Model 321 to make the 0 V output correspond to
100 K.
ANOL?
Analog Output Minimum (Low) Query.
Input:
ANOL?
Returned:
XXX.X
Remarks:
Returns the current value of the temperature in kelvin which gives 0 V output.
