Set modulation oscillator frequency (short form)
:FREQ
Set modulation oscillator frequency
:INC
Set modulation oscillator frequency step size
Data type :

INTF1? or INTF2? or INTF3? or
INTF4? or INTF5? or INTF6?
Prepares message containing information on modulation oscillator
setting in one of the following formats:
:INTF1:FREQ <nr2>;INC <nr2>;<waveform>
:INTF6:<standard> <nr1>
where: <waveform> is a program mnemonic (SIN or TRI) indicating
the waveform shape and <standard> is a program mnemonic
(CTC1, CTC2, USER or TEMP) indicating the continuous tone
signalling standard selected.
Examples:
:INTF2:FREQ 440.0;INC 100.0;SIN
:INTF3:CTC1 5
