[SENSe<Ch>:]SWEep:AXIS:FREQuency <Scale>
Selects either the channel base frequency or one of the port frequencies as the stimu-
lus axis in all diagrams of the active recall set. This command has no effect if no port-
specific frequencies are defined.
Suffix:
<Ch>
.
Channel number
Parameters:
<Scale> String parameter, one of the following signals:
'Channel Base; Source' - base channel frequency
'Port 1; Source' - source frequency at port 1
'Port 2; Source' - source frequency at port 2
...
'Gen 1; Source' - external generator frequency 1
...
'Pmtr 1; Receiver' - external power meter frequency 1
...
*RST: 'Channel Base: Source'
Example:
*RST; FREQ:STAR 1 GHz; STOP 2 GHz
Define a base channel frequency range between 1 GHz and 2
GHz. This frequency is also used as an (initial) frequency range
for all test ports and external generators.
SOUR:FREQ1:CONV:ARB:IFR 1, 1, 1E+9, SWE
Convert the source frequency at test port no. 1 to the range
between 2 GHz and 3 GHz.
SWE:AXIS:FREQ 'Port 1; Source'
Select the source signal at port 1 as the reference signal for fre-
quency definitions.
FREQ:STAR 3 GHz; STOP 4 GHz
Shift all frequency ranges by +1 GHz.
SWE:AXIS:FREQ 'Port 2; Source'
Select the source signal at port 2 as the reference signal for fre-
quency definitions.
FREQ:STAR?; STOP?
Query the frequency range at test port 2. The response is
2000000000;3000000000.
