Setting the oscillator
To set an oscillator level, use the commands given below.
• “POWMOD” on page 404
• “POWE” on page 403
Either a voltage or a current can be used to set the oscillator level. First, specify whether
you use voltage or a current with the “POWMOD” command and then set a level with the
“POWE” command.
To set the oscillator frequency during oscillator level sweep and dc bias sweep, use the
command given below.
• “CWFREQ” on page 285
Setting a dc bias
To turn on or off the dc bias output or to select an output mode, use the commands given
below.
• “DCO” on page 291
• “DCMOD” on page 291
To set a dc bias level, use the commands given below.
• “DCI” on page 290
• “DCV” on page 295
To set a dc bias output range, use the command given below.
• “DCRNG” on page 294
If the dc bias output is either in constant voltage mode or in constant current mode, use the
commands given below to set the limit of the current output or the voltage output. In both
constant voltage mode and constant current mode, set the limit of output level in terms of
voltage.
