6 RLC Swept SA Measurement Front-Panel & SCPI Reference
Meas Setup
data is issued in printed form when an SNS is purchased or can be read from the analyzer’s
Noise Figure application if installed, or other Agilent noise figure instruments that support the
SNS (NFA and ESA with option 219).
When first entering the Swept SA measurement the “State” will be set to OFF and the 28v BNC
drive and SNS turned off to ensure the two are in sync. When the Swept SA measurement is
exited, the “State” parameter will be set to OFF and the 28v BNC and SNS drive turned off.
For making manual noise figure measurements the following setup is recommended:
•
Set the SPAN to Zero
•
Set attenuation to 0 dB
•
Set the PRE-AMP ON
•
Set the RBW to 4MHz
•
Set the Detector to AVERAGE
•
Set the sweep time to 16ms - sets the variance correctly for good results.
•
Set a Band/Interval Power Marker function and set the interval over the full width of trace i.e.
Left to 0s and Right to 16ms
Noise Source
This menu allows you to turn the noise source power on or off when making manual noise figure
measurements.

Key Path Meas Setup
Remote Command :SOURce:NOISe:TYPE NORMal | SNS
:SOURce:NOISe:TYPE?
Example SOUR:NOIS:TYPE NORM
Couplings If no SNS is connected, this parameter will be set to “Normal”
When Type is set to “SNS” and the SNS is disconnected, this parameter gets bumped to
“Normal”
When an SNS is not connected, the SNS type will be grayed (disabled).
Preset Normal
State Saved Saved in instrument state.
Range Normal | SNS

Notes In previous Noise Figure analysis applications, this command
could optionally be preceded with the :SENSe keyword. The
optional :SENSe keyword is no longer supported.
