Remote Operation
4-13
RI?:
Remote Inhibit Status Query
Input:
RI?
Returned:
0
if the remote inhibit is inactive, or
1
if it is active.
Remarks:
One character plus up to two terminators are returned.
VOUT? (V?):
Output Voltage Query
Input:
VOUT? or V?
Returned:
A number between 0 and ±32.0000 V.
Remarks:
Returns nine characters plus up to two terminators.
VMAX:
Programs an upper (soft) voltage limit that the unit will accept.
Input: VMAX[voltage]
where
[voltage]
= 0 to +32.0000 V.
Remarks:
Normal resolution truncates the value to 0.01 place. High resolution truncates the value to the
0.001 place. The initial condition is +000.0000 V. The voltage limit is always forced to a plus.
VMAX?:
Voltage Limit Query.
Input: VMAX?
Returned:
A value between 0 and +32.0000 V.
Remarks:
Returns a nine character value with up to two terminators.
VSET (V):
Programs the output voltage in the voltage mode.
Input: VSET[voltage]
or
V[voltage]
where
[voltage]
= 0 to +32.0000 V.
Remarks:
Normal resolution truncates the value to 0.01 place. High resolution truncates the value to the
0.001 place. The initial condition is +00.0000 V. The voltage setting is always forced to a “+.”
Setting is limited by VMAX. Control Bus inputs 4 places, display rounds to 0.01 or 0.001 place.
VSET?:
Output Voltage Setting Query.
Input: VSET?
Returned:
A value between 0 and +32.0000 V.
Remarks:
Returns a nine character value with up to two terminators.
