If unchecked (default), you can define the Rear IF Frequency manually. However, this
frequency is also used internally and is possibly not optimal for the Direct IF Access
Input / Output ports. If you activate "Auto Determine IF Out", the analyzer firmware
selects suitable rear IF frequencies.
Remote command:
[SENSe<Ch>:]PATH<Pt>:IFOutauto
[SENSe<Ch>:]PATH<Pt>:MEASurement:IFOutauto?
[SENSe<Ch>:]PATH<Pt>:REFerence:IFOutauto?
Rear Input Path
This selection is only enabled if "Rear IN" is used as Receiver Input. Internally three
different paths are available for the IF signal.
●
"Direct" – frequency range 5kHz to 1 GHz
●
"LP_60M" – low pass, frequency range 5 kHz to 60 MHz
●
"BP_279M" – band pass, frequency range 260 MHz to 290 MHz
The limitation of the Frequency to the smaller frequency ranges increases the system
performance. Standard case could be a fixed frequency input, as it is for the mm-con-
verter IF frequency.
Remote command:
[SENSe<Ch>:]PATH<Pt>:IFINpath
[SENSe<Ch>:]PATH<Pt>:MEASurement:IFINpath?
[SENSe<Ch>:]PATH<Pt>:REFerence:IFINpath?
Rear IF Frequency
Sets the frequency at the related Direct IF access ports as a linear transformation of
the channel base frequency f
b
.
This setting is available in one of the following cases:
●
"Rear IN" is used as Receiver Input
●
Rear Out is used and Auto Determine IF Out is disabled.
Remote command:
[SENSe<Ch>:]PATH<Pt>:IFRequency
[SENSe<Ch>:]PATH<Pt>:MEASurement:IFRequency?
[SENSe<Ch>:]PATH<Pt>:REFerence:IFRequency?
Frequency Result
Shows the frequency resulting from the from Rear IF Frequency configuration.
Common controls
Modified "Port Settings" take effect on "Apply" or "OK". Use "Cancel" to discard possi-
ble changes.
+/x
Use the "+" button next to the rightmost tab title, to add a custom tab. In the Displayed
Columns dialog that opens, give the new tab a name ("Tab Title") and select the port
parameters to display in the tab's configuration table.
Custom tabs can be deleted using the "x" icon in the tab title.
