RF signal and spectrum analysis is a critical capability for debugging and verifying RF designs. From component characterization to environmental studies or complex signal evaluation, spectrum analyzers are an important tool for RF test. 

Learn all about SIGLENT’s spectrum analyzers in terms of key specifications, use cases, and limitations in these RF signal analysis applications here:

Key specifications for RF signal analyzers include displayed average noise level (DANL) and phase noise. Real-time analyzers also have special display modes as well as the 100% Probability of Intercept specification for short duration RF Pulse analysis.

Learn about the options, limits, and how to use key specifications in your application:

Electromagnetic Interference testing includes verifying radiated and conducted emissions as well as immunity to such emissions. EMI testing starts with pre-compliance debugging and spot checking and goes all the way through full compliance testing at a certified lab. Compliance testing is required to bring electronics to market. Learn more about pre-compliance testing that can save time and money here:

IQ modulation is the backbone of many communication protocols. From QAM to QPSK or Wi-Fi to 5G NR, IQ demodulation at high clock rates is a critical tool for evaluating real world RF systems.

Learn about the options, limits, and analysis of IQ demodulation from setup to measured error vector magnitude and bit error rate testing for known signal types including:

ASK: 2ASK;
FSK: 2FSK, 4FSK, 8FSK, 16FSK;
MSK: GMSK;
PSK: BPSK, QPSK, OQPSK, 8PSK; DPSK: DBPSK, DQPSK, D8PSK, π/4 -DQPSK, π/8 -D8PSK;
QAM: 16, 32, 64, 128, 256

The SSA5000A spectrum analyzers have additional advanced capabilities for more complex signal verification. Analyze Bluetooth signals, characterize noise figure and phase noise, or study RF pulse shape and duration with advanced options for the SSA5000A series spectrum analyzers.

Debugging and analysis on instrument is great, but automation and programmatic control are required for efficient testing from prototyping through manufacturing. Learn more about controlling Siglent analyzers with these help articles:
