Selecting a different source is necessary, if the bandwidth of the "Combiner Out" signal
does not fully cover the required receiver frequency range. For example, if a filter is
used at the combiner output to cut off the intermodulation products originating from the
combiner.
Remote command:
SOURce<Ch>:POWer:CORRection:IMODulation:PORT
Power
Power of the lower and of the upper tone. Both powers are always kept equal. For
power sweeps, the start and stop power must be set in the Frequencies and Power
Dialog.
Remote command:
SOURce<Ch>:POWer<PhyPt>[:LEVel][:IMMediate][:AMPLitude]
Tone Distance
Defines the frequency difference between the upper and the lower tone. The tone dis-
tance is kept constant across the entire sweep.
Remote command:
[SENSe<Ch>:]FREQuency:IMODulation:TDIStance
Prepare Measurement of IM Order
Selects the orders of the measured intermodulation products. Each order requires an
additional measurement at a different frequency, therefore the measurement time
increases with the number of selected orders. If a higher-order IM is selected, its fre-
quency can exceed the upper or lower frequency limit of the analyzer. Use the "Fit Fre-
quency Range" button in the Frequencies and Power Dialog to restrict the sweep
range accordingly.
Remote command:
[SENSe<Ch>:]FREQuency:IMODulation:ORDer<Im>[:STATe]
Step Attenuator
Defines the value for the receiver step attenuator at the receiving port. Same setting as
in the "Power" tab of the "Stimulus" softtool; see "Step Attenuators" on page 384.
Remote command:
[SENSe<Ch>:]POWer:ATTenuation
Meas Bandwidth
Defines the bandwidth of the IF filter at the receiving port.
The setting is identical with the "Bandwidth" setting on the "Bandwidth" tab of the
"Power Bw Avg" softtool; see Chapter 6.9.2, "Bandwidth Tab", on page 387.
Remote command:
[SENSe<Ch>:]BWIDth[:RESolution]
Selectivity
Defines the selectivity of the IF filter of the receiving port.
The setting is identical with the "Selectivity" setting on the "Bandwidth" tab of the
"Power Bw Avg" softtool; see Chapter 6.9.2, "Bandwidth Tab", on page 387.
