ON
The frequencies are set automatically (by the analyzer firm-
ware).
*RST: OFF
Usage: Setting only
Options: R&S ZNA-B26
Manual operation: See "Auto Determine IF Out" on page 622
[SENSe<Ch>:]PATH<Pt>:IFRequency
<Numerator>, <Denominator>, <Offset>,
<Sweep type>
Defines the freqency conversion formula for Direct IF Access Input / Output ports IF
Reference <Pt> and IF Meas <Pt> in channel <Ch>.
For <Sweep type> FB, the IF frequency f
IF
is calculated according to
f
IF
= <Numerator>/<Denominator> * f
b
+ <Offset>,
where f
b
represents channel base frequency.
For <Sweep Type> CW, f
IF
is calculated according to
f
IF
= <Offset>,
i.e. f
IF
is constant.
Make sure the converted frequency or frequency range is within the Direct IF Access
Input / Output ports' frequency range. If the resulting frequencies are not (completely)
within the allowed range, the analyzer returns an error message. Nevertheless, the fre-
quency formula is applied.
Note: This setting only takes effect in one of the following cases:
●
[SENSe<Ch>:]PATH<Pt>:REFerence:IFSWitch? is set to IN.
●
[SENSe<Ch>:]PATH<Pt>:REFerence:IFSWitch? is set to OUT and
[SENSe<Ch>:]PATH<Pt>:IFOutauto is set to OFF.

Setting parameters:
<Numerator> The specified numerator is rounded to the next higher integer;
zero is not allowed.
<Denominator> The specified denominator must be positive. It is rounded to the
next higher integer.
<Offset> The specified offset value is rounded to (positive or negative)
multiples of 1 Hz.
