Keysight NFA X-Series Getting Started and Troubleshooting Guide 23
Quick Start
Using the U7227-Series USB Preamplifiers in Noise Figure Measurements
In the noise figure measurement application, the signal analyzer will respond in
the following manner when the USB cable of the U7227-Series USB
Preamplifier is plugged into one of the analyzer’s ports:
1.
The sweep will pause momentarily while the “Hardware Configuration
Updating” message appears on the signal analyzer display. See
Figure 1-3
“Hardware Configuration Updating” Message
2.
The USB preamplifier’s calibration data, such as gain, noise figure, and
S-parameters, will be automatically downloaded into the analyzer.
3.
The “Ready” LED is lit on the USB preamplifier.
4.
The USB preamplifier’s model and serial number will be displayed. See
.
The USB preamplifier’s RF output cable, connector loss, and frequency
response are accounted for in the data that is automatically downloaded
into the analyzer’s memory. The calibration data is not user accessible.
