Description

With the widespread increase of wireless technologies, the spectral environment is filled with interference. Interference results in network quality deterioration and breakdown of communication links. Additionally, the prevalent use of digital modulation and burst-transmission methods have made it difficult to reliably detect interference sources. FieldFox’s real-time spectrum analyzer (RTSA) helps with interference detection.

RTSA’s fast overlapping FFT processing technique allows gap-free measurements of signals as narrow as 12 µs, with full amplitude accuracy, with 100% POI. In cases where detection of the signal is the critical factor, independent of amplitude accuracy, FieldFox’s 10 MHz real-time bandwidth allows pulses as narrow as 22 ns to be seen on the display.

The spectrum density view displays three dimensional data on a two dimensional display. It uses color to show the number of times a frequency and amplitude point is detected during a capture interval. This is an excellent way to understand and visualize the spectral content. For example, with RTSA you can detect a low-level signal in the presence of a high power transmitter using the spectrum density view.

Finding an elusive signal can take hours or days. With FieldFox’s recording and playback, the analyzer can be set to collect data over time, and the data can be analyzed later offline.

Configuration information

Option 350 requires the spectrum analyzer option (option 233). The preamplifier (option 235) is highly recommended, as elusive signals often have low power levels.

Option 350 can be added as a product upgrade.

Upgrading or adding option 350 to an existing FieldFox

Option 350 requires a FieldFox that has a fast processor. The fast processor is called CPU2. All N995x and N996x analyzers include CPU2. On other FieldFox models, if the serial number starts with MY5607/SG5607/US5607, it has CPU2. If the serial number prefix is different, then the analyzer firmware needs to be checked to see if the instrument has been upgraded with N9910HU-100/200/300/400 to have CPU2. CPU check on a FieldFox: [System] {Service Diagnostics} {System Information}. Check the information for BIOS Rev. More information on CPU upgrades: www.keysight.com/find/fieldfox-sw-hw-upgrade.
