Operating Manual 1145.1084.12 – 30 916
<Ch>
Channel number. If unspecified the numeric suffix is set to 1.
<log_port>
Logical port number. The logical ports must be defined using
SOURce<Ch>:LPORt<log_port> <phys_port1>,<phys_port2>. An n port
analyzer supports a maximum of n/2 (n even) or (n – 1)/2 (n odd) logical ports.
<real>
<imaginary>
Real and imaginary part of the port impedance. <imaginary> may be omitted to
define a real impedance.
Range [def.
unit]
1mΩ to 10 MΩ for the real part [Ω]
– 10 MΩ to 10 MΩ for the imaginary part [Ω]
*RST value
100 Ω (real impedance)

Command
Types
Device-specific, command or query
Example:
*RST; :CALC:PAR:DEL 'TRC1'
Reset the analyzer and delete the (default) trace for channel
no. 1.
SOUR:LPOR1 1,2
Combine the physical ports no. 1 and 2 to define the balanced (logical) port no. 1.
LPOR1:ZDIF 27, 2
Specify a complex differential mode reference impedance of 27Ω + j * 2Ω for the
defined port.
[SENSe<Ch>:]NFIGure...
This subsystem configures the noise figure measurement.
[SENSe<Ch>:]NFIGure:ISNoise <Boolean>
Qualifies whether the analyzer assumes an ideal T0 source noise.
<Ch>
Channel number. If unspecified the numeric suffix is set to 1.
<Boolean>
ON | OFF – Switches the LO oscillator on or off.
*RST value
OFF

[SENSe<Ch>:]NFIGure:NDUT <Boolean>
Configures the noise figure measurement for a narrowband DUT.
<Ch>
Channel number.
<Boolean>
ON | OFF – suitable if a narrowband DUT (< 50 MHz) or a broadband DUT
