Mode sweeps). The receiver frequency is valid for all ports.
The frequency formula is applied even if the analyzer returns an error message, because the
frequency is outside the allowed range.
<Ch>
Channel number.
<Mtr>
Power meter 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 channel base frequency (parameter SWEep). For
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 power meter's
receive frequency range [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].
*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.
*RST value
SWEep

Types
Device-specific, command or query.
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:PMET1:DEF 'USB Power Meter', 'NRP-Z55', 'usb', '100045'
Configure an R&S NRP power meter as external power meter no. 1, assigning
the name USB Power Meter and an serial number 100045.
SENS:FREQ:CONV:ARB:PMET 2,1,1E+9,SWE
Convert the receiver frequency to the range between 3 GHz and 3.2 GHz.
[SENSe<Ch>:]FREQuency:CONVersion:AWReceiver[:STATe] <Boolean>
Qualifies whether a-waves (outgoing waves) are measured at the source or at the receiver frequency. The
setting is relevant for all frequency-converting measurements.
<Ch>
Channel number.
