MODULATION FREQUENCY
INTF1 or INTF2 or INTF3 o
INTF4 or INTF5 or INTF6
Set modulation oscillator frequency (short form)
:FREQ Set modulation oscillator frequency
:INC Set modulation oscillator frequency step size
Data type :

Allowed suffices : Any one of: GHZ, MHZ, KHZ or HZ
Default suffix : HZ
:SIN
Select sinusoidal waveform
:TRI Select triangle waveform
:SQU Select square waveform
:UP Go UP one step
:DN Go DOWN one step
:RETN Return to original setting

INTF1? or INTF2? or INTF3? o
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 standar
selected.
Examples:
:INTF2:FREQ 440.0;INC 100.0;SIN
:INTF3:CTC1 5
