SOURce<Ch>:]FREQuency:CONVersion:MIXer:FUNDamental RF | LO
Selects the mixer input signal which is at the fundamental power (channel power, to be defined by
means of
SOURce<Ch>:POWer<Pt>:STARt, SOURce<Ch>:POWer<Pt>:STOP,
SOURce<Ch>:POWer<Pt>[:LEVel][:IMMediate][:AMPlitude]
).
<Ch> Channel number.
Parameters RF – mixer input signal
LO – local oscillator signal
*RST value RF
SCPI, Command Types Device-specific, command or query.
Example:
See SOURce<Ch>:FREQuency:CONVersion:MIXer:PFIXed
SOURce<Ch>:FREQuency:CONVersion:MIXer:PFIXed <fixed_power>
Defines a fixed power, to be assigned either to the RF or to the LO signal (the signal not addressed by
SOURce<Ch>:]FREQuency:CONVersion:MIXer:FUDamental RF | LO
).
<Ch> Channel number.
<fixed_power>
Fixed power.
Range [def. unit] –40 dBm to +10 dBm. The exact range depends on the analyzer
model or external generator used; refer to the data sheet [dBm]. UP
and DOWN increment/decrement the source power in 0.1-dB steps.
*RST value –25 dBm
SCPI, Command
Types Device-specific, command or query.
Example:
*RST; SOUR:FREQ:CONV:MIX:PFIX –10
Reset the analyzer and specify a fixed power of –10 dBm.
SOUR:FREQ:CONV:MIX:FUND LO
Assign the fundamental frequency to the LO signal. The fixed
frequency is automatically assigned to the RF signal.
SOURce<Ch>:GROup<group_no> <log_port1>,<log_port2>
Defines a group of measured ports numbered <group_no> containing a continuous range of logical
ports <log_port1> and <log_port2>.
<Ch> Channel number.
<group_no> Port group number. If unspecified the analyzer automatically selects
an unused port group number (existing port groups are not
overwritten).
Range [def.
unit]
Port groups must contain at least one logical port and must not
overlap, so the maximum number of port groups for an n-port
analyzer is n. [–]
