Operating Manual 1145.1084.12 – 30 977
Restrict the base frequency range to 75 GHz to 100 GHz.
SOUR:FREQ1:CONV:ARB:IFR 1, 6, 5E+7, SWE
Increase the RF source frequency at port 1 by 50 kHz.
SOUR:FREQ1:CONV:ARB:CFR 1, 1, 3E+8, SWE
Adjust the frequency axis of the converter output.
SOUR:POW:CONV:OFFS 3, CPAD
Increase the output power of the converter by +3 dB..
SOURce:POWer:CORRection:CONVerter:LEVel:OFFSet 20
Define a 20 dB cal power offset to account for an additional amplifier in the signal
path.
SOURce<Ch>:FREQuency<Pt>:CONVersion:ARBitrary:EFRequency<Gen>
<Boolean>, <numerator>, <denominator>, <offset>, CW | FIXed | SWEep
Defines an external generator frequency for frequency-converting measurements. The external generator
frequency is either a range (for frequency sweeps) or a CW frequency (for power, time and CW Mode
sweeps).
<Ch>
Channel number.
<Pt>
Test port number of the analyzer. This suffix is ignored because the generator
is referenced via <Gen>.
<Gen>
Generator number
<Boolean>
Switch the generator on or off.
<numerator>
<denominator>
<offset>
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.
In manual control, the <offset> is defined as a product of a ratio of two
integers times a multiple of 1 Hz.
Range [def. unit]
The converted frequency or frequency range must be within the external
generator's frequency range [Hz]. In addition the following restrictions apply:
<numerator> – Values are rounded to positive or negative integer numbers [1]
<denominator> – Values are rounded to positive integer numbers; zero is not
allowed [1]
<offset> – Values are rounded to (positive or negative) multiples of 1 Hz [Hz].
*RST value
The default frequency/frequency range corresponds to the sweep range or CW
frequency of the analyzer, i.e.
<numerator> = <denominator> = 1
<offset> = 0 Hz
Sweep type
Parameters
SWEep – The full formula is applied. For frequency sweeps, the command
defines a sweep range.
CW | FIXed – The reduced formula with f
b
= 0 is applied. f
r
= <offset>; the
command defines a fixed frequency.
