Real-Time Spectrum Analyzer (RTSA) Measurement Guide : IA Real-Time Spectrum Analyzer (Option 24) : Introduction
 
Introduction
The Interference Analyzer (IA) real-time spectrum analyzer (RTSA) and MA2700A handheld InterferenceHunter™ are the ideal solution for anyone conducting coverage testing of RF and microwave communications systems, including 5G and LTE networks.
The Interference Analyzer (IA) RTSA application assists you in finding the source of interfering signals with the use of MA2700A handheld InterferenceHunter, GPS receiver, and directional antenna. Note that it is required to enable the GNSS receiver in the GNSS (GPS) settings of the instrument. Refer to instrument user guide.
It is recommended to use the RTSA interference finder mode at all times to achieve better interference hunting, unless a frequency span wider than the RTSA option (up to 110 MHz) is required. This is because the measurement cycle time is faster in RTSA mode, resulting in increased possibility of locating the interfering signals. With the MA2700A, a vector line to an interfering signal can be added to a map in the instrument with a click of the trigger on the handle.
A basic understanding of the measurement concepts presented in Real-Time Spectrum Analyzer (Option 199) Overview is recommended before performing the procedures in this chapter. Refer to the following sections for a better understanding of the RTSA application:
• Selecting the Analyzer
• RTSA GUI Overview (only applies to RF Spectrum RTSA view, no spectrogram view in IA RTSA measurement)
• Main Menu
• Status Panel (RTSA)
• Setting Frequency Parameters
• Setting Amplitude Parameters
• Setting Bandwidth Parameters
• Setting Trace and Cursor Parameters (Cursor parameters don’t apply to IA RTSA measurement)
• Setting Sweep Parameters
• Setting Up Markers
• Setting Up Limit Lines
• IQ TRIGGER Menu
• AM/FM Audio (Requires Option 24 or Option 509)
• AM/FM Modulation Measurement (Option 509)
• Interference Finder (Option 24)
• Status Panel (AM/FM Audio)
IA RTSA application includes the use of additional functions beyond frequency, span, amplitude, and marker functions. Refer to Setting Up Advanced Measurements and Interference Polar to cover field measurements and additional smart measurements provided by these newly added modes such as interference map and interference polar.
