Example:
*RST; FREQ:STAR 0.5E+9; STOP 1E+9
Reset the analyzer (activating a frequency sweep) and set the sweep
range between 1 GHz and 1.1 GHz.
FREQ:CONV:HARM:ORD 4; SPOR 1; RPOR 2
Configure a 4
th
harmonic measurement with source port 1 and receive
port 2. The measurement is still not enabled.
FREQ:CONV HARM
Enable the configured harmonic measurement.
CALC:PAR:MEAS? "TRC1"
Query the measured quantity. The analyzer measures the wave
quantity b2, the response is
'B2D1SAM'
.
FREQ:CONV:HARM:RELative ON
Enable the relative harmonic measurement, creating a new channel
and a new trace
Trc2 .
CALC2:PAR:MEAS? "TRC2"
Query the measured quantity in the new channel no. 2. The analyzer
still measures the wave quantity b2, the response is
'B2D1SAM'
.
CALC2:MATH:STAT?
Check whether the active trace in channel no. 2 (i.e. Trc2) is a
mathematical trace
:
the response is
1
.
[SENSe<Ch>:]FREQuency:CONVersion:ARBitrary <numerator>, <denominator>,
<offset>, CW | FIXed | SWEep
Defines the receiver frequency for frequency-converting measurements. The receiver frequency is
either a range (for frequency sweeps) or a CW frequency (for power, time and
CW Mode sweeps). The
receiver frequency is valid for all ports.
<Ch> Channel number.
<numerator>
<denominator>
<offset>
Parameters of the frequency formula. The receiver frequency f
r
is
calculated according to
f
r
= <numerator>/<denominator>*f
b
. + <offset>
where f
b
represents the sweep range (for frequency sweeps,
parameter SWEep). For power, time and CW Mode sweeps
(parameters CW or FIXed), f
b
= 0.
The conversion formula for f
r
is ZVR-compatible but differs
from manual control where the ratio
<numerator>/<denominator> also multiplies the <offset>.
Range [def. unit] The converted frequency or frequency range must be within the
analyzer's frequency range, depending on the instrument model
[Hz]. In addition the following restrictions apply:
<numerator> – Values are rounded to positive or negative integer
numbers; zero is not allowed [1]
<denominator> – Values are rounded to positive integer numbers
[1]
<offset> – Values are rounded to (positive or negative) multiples of
1 Hz [Hz].
