SOURce<Ch>:FREQuency<PhyPt>:CONVersion:ARBitrary:EFRequency<Gen>
<Boolean>, <Numerator>, <Denominator>, <Offset>, <SweepType>
Defines an external generator frequency for frequency-converting measurements. The
external generator frequency is either a range (for frequency sweeps) or a CW fre-
quency (for power, time and CW Mode sweeps).
Suffix:
<Ch>
.
Channel number
<PhyPt> Test port number of the analyzer. This suffix is ignored because
the generator is referenced via <Gen>.
<Gen> Generator number
Parameters:
<Boolean> Switch the generator on or off.
<Numerator> Parameters of the frequency formula. The source frequency f
s
is
calculated according to f
s
= <Numerator>/<Denominator> * f
b
+
<Offset> where f
b
represents the channel base frequency
(parameter SWEep). For parameters CW or FIXed, f
b
= 0.
Note: The <Offset> parameter also includes the "Offset Ratio"
in manual control.
Range: The converted frequency or frequency range must
be within the external generator's frequency range.
In addition the <Numerator> values are rounded to
positive or negative integer numbers.
*RST: The default frequency/frequency range corresponds
to the sweep range or CW frequency of the ana-
lyzer, i.e. <Numerator> = <Denominator> = 1, <Off-
set> = 0 Hz.
Default unit: 1
<Denominator> See above, <Numerator>
Range: The converted frequency or frequency range must
be within the external generator's frequency range.
In addition the <Denominator> values are rounded
to positive integer numbers; zero is not allowed.
*RST: 1
Default unit: 1
<Offset> See above, <Numerator>
Range: The converted frequency or frequency range must
be within the external generator's frequency range.
In addition the <Offset> values are rounded to (pos-
itive or negative) multiples of 1 Hz.
*RST: 0
Default unit: Hz
