<SweepType> CW | FIXed | SWEep
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; the com-
mand defines a fixed frequency.
*RST: SWEep
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.
SOUR:FREQ2:CONV:ARB:IFR 2, 1, 1E+9, SWE
Convert the source frequency at test port no. 2 to the range
between 3 GHz and 3.2 GHz.
SENSe:FREQuency:CONVersion:GAIN:LMCorrection ON
Enable the load match correction for all conversion gains.
SENSe:FREQuency:CONVersion?
Query the measurement mode. The response is ARB, because
the port frequency definition also activates the arbitrary mode.
SENSe:FREQuency:CONVersion FUND
De-activate the arbitrary mode, cancel the port frequency defini-
tion.
Manual operation:
See "Freq. Conversion" on page 564
SOURce<Ch>:FREQuency:CONVersion:MIXer:PMFixed <arg0>[, <arg1>]
Assigns a fixed power to the RF, LO 1, LO 2, or to the IF signal.
Suffix:
<Ch>
.
Channel number
Parameters:
<arg0> RF | LO | LO1 | LO2 | IF
RF – mixer input signal
LO | LO1 – local oscillator signal no. 1
LO2 – local oscillator signal no. 2, for 2-stage mixer measure-
ments ([SENSe<Ch>:]FREQuency:CONVersion:MIXer:
STAGes)
IF – mixer output signal
<arg1> Fixed power
Range: The exact range depends on the analyzer model or
external generator used; refer to the data sheet.
*RST: -25 dBm (for LO)
Default unit: dBm
Example: See [SENSe<Ch>:]FREQuency:CONVersion:MIXer:
MFFixed
Manual operation: See "Power tab" on page 599
