Instructions

80
Example :DDS:OFFSet 0.5 /* Set signal source waveform
offset 0.5V*/
:DDS:OFFSet? /*return 5.00000e-01*/
DDS:DUTY
Syntax :DDS:DUTY <duty>
:DDS:DUTY?
Description : Sets or queries the space ratio of signal source signals
Parameter :<duty> ::= 0--99
Return : The query returns the null ratio value
Example :DDS:DUTY 50 /* Sets the signal source signal to the
air ratio for 50%*/
:DDS:DUTY? /*return 50*/
DDS:WAVE:MODE
Syntax :DDS:WAVE:MODE <bool>
:DDS:WAVE:MODE?
Description : Sets or queries the signal source modulation status
Parameter :<bool> ::= {{1 | ON} | {0 | OFF}
Return :return ON,OFF
Example :DDS:WAVE:MODE ON /* Turn on the signal source
modulation */
:DDS:WAVE:MODE? /* return ON*/
DDS:MODE:TYPE
Syntax :DDS:MODE:TYPE <type>
:DDS:MODE:TYPE?
Description : Set or query the source modulation type
Parameter :<type> ::= { AM| FM}
Return : Returned by the query AM，FM
Example :DDS:MODE:TYPE AM /*Set the signal source modulation
type AM*/
:DDS:MODE:TYPE? /*Returned by the queryAM*/
