Chapter 2 Command System RIGOL
Programming Guide for DM3000
2-9
The query returns 0, 1, 2, 3 or 4.
Explanation
The DCV function must be specified at least one time before using
this command.
6. :MEASure:VOLTage:DC:IMPEdance
Syntax
:MEASure:VOLTage:DC:IMPEdance?
:MEASure:VOLTage:DC:IMPEdance {10M|10G}
Function
Sets the DC impedance to 10MΩ or >10GΩ.
The query returns 10M or 10G.
Explanation
>10G is available only in ranges of 200mV, 2V, 20V of the DC
voltage.
7. :MEASure:VOLTage:DC:DIGIt
Syntax
:MEASure:VOLTage:DC:DIGIt?
:MEASure:VOLTage:DC:DIGIt {INC|DEC|5|6|7}
Function
Sets the display digit for DC voltage measurement values.
The query returns 5, 6 or 7.
Explanation
DEC and INC settings are invalid when the display digits are 5
and 7, respectively.

the digit is 6
7
the digit is 7
Example
Setting the display digit to 7:
:MEASure:VOLTage:DC:DIGIt 7
Decreasing the display digit by one bit:
:MEASure:VOLTage:DC:DIGIt DEC
8. :MEASure:VOLTage:DC:RATIo?
Syntax
:MEASure:VOLTage:DC:RATIo?
Function
The query returns the ratio of DC voltages in two circuits in the
form of scientific notation such as +1.74214858E-01.
Explanation
The instrument should input two DC voltages at the same time.
