[:SOURce[<n>]]:FUNCtion:DUALTone:OFFSETFreq 
 
Syntax 
[:SOURce[<n>]]:FUNCtion:DUALTone:OFFSETFreq {<frequency>|MINimum|MAXimum} 
[:SOURce[<n>]]:FUNCtion:DUALTone:OFFSETFreq? 
 
Description   
Sets the offset frequency of the dual-tone signal of the specified channel. 
Queries the offset frequency of the dual-tone signal of the specified channel. 
 
Parameter 
 
Remarks   
  When [:SOURce[<n>]] or [<n>] is omitted, the system sets the related parameters of CH1 by default. 
  The offset frequency, frequency 1 and frequency 2 satisfy the following relations. 
;
 
Wherein, 
  ——offset frequency; 
  ——frequency 1; 
 
——frequency 2. 
 
Return Format 
The query returns the offset frequency in scientific notation, with 7 effective digits. For example, 
2.000000E+03 (the offset frequency is 2 kHz). 
 
Example 
:SOUR1:FUNC:DUALT:OFFSETF 2000 /*Sets the offset frequency of the dual-tone signal of CH1 to 2 kHz.*/ 
:SOUR1:FUNC:DUALT:OFFSETF?       /*Queries the offset frequency of the dual-tone signal of CH1 and the 
query returns 2.000000E+03.*/ 
 
 
[:SOURce[<n>]]:FUNCtion:PRBS:BRATe 
 
Syntax 
[:SOURce[<n>]]:FUNCtion:PRBS:BRATe {<bit_rate>|MINimum|MAXimum} 
[:SOURce[<n>]]:FUNCtion:PRBS:BRATe? [MINimum|MAXimum] 
 
Description   
Sets the PRBS bit rate of the specified channel. 
Queries the PRBS bit rate of the specified channel. 
 
Parameter 
 
Remarks   
When [:SOURce[<n>]] or [<n>] is omitted, the system sets the related parameters of CH1 by default. 
 
Return Format 
The query returns the PRBS bit rate in scientific notation, with 7 effective digits. For example, 
3.000000E+03 (the PRBS bit rate is 3 kbps).
