IQ:OUTP:BIAS:COUP ON
activates coupling of bias settings of the two components.
Example:
[:SOURce<hw>]:IQ:OUTPut:BIAS:I <I>
This command sets the amplifier bias.
The maximum overall voltage depends on the I/Q output type.
●
Single ended: IQ:OUTP:POW:PEP + SOUR:IQ:OUTP:BIAS:I|Q <= 3.7 volts.
●
Differential:
0.5 * IQ:OUTP:POW:PEP + SOUR:IQ:OUTP:BIAS:I|Q + 0.5 * SOUR:
IQ:OUTP:OFFS:I|Q <= 3.7 volts.
For two-path instruments, the outputs are assigned with command
[:SOURce]:BB:IQOutput:SOURce on page 728.
