Example:
*RST; FREQ:STAR 1E+9; STOP 1.1E+9
Reset the analyzer (activating a frequency sweep) and set the
sweep range between 1 GHz and 1.1 GHz.
SYST:COMM:RDEV:GEN1:DEF 'Ext. Gen. 1', 'SME02',
'gpib0', '21'
Configure an R&S SME02 generator as external generator no.
1, assigning the name "Ext. Gen. 1" and a GPIB address 21.
SOUR:FREQ:CONV:ARB:EFR ON, 1, 4, 1E+9, SWE
Switch the generator on and convert the generator frequency to
the range between 1.25 GHz and 1.275 GHz.
Manual operation: See "Frequency Conversion Formula" on page 531

<Numerator>, <Denominator>, <Offset>, <SweepType>
Defines the port-specific frequency for frequency-converting measurements. The port
frequency is either a range (for frequency sweeps) or a CW frequency (for power, time
and "CW Mode" sweeps).
Note: The frequency formula is applied even if the analyzer returns an error message,
because the frequency is outside the allowed range.
Suffix:
<Ch>
.
Channel number
<PhyPt> Test port number of the analyzer
Parameters:
<Numerator> Parameters of the frequency formula. The port frequency f
p
is
calculated according to f
p
= <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 analyzer's frequency range, depend-
ing on the instrument model. In addition the
<Numerator> values are rounded to positive or neg-
ative integer numbers; zero is not allowed.
*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
