Data Sheet

EMI pre-compliance and diagnostic measurements are easy with the

RSA306B and SignalVu-PC. Transducer, antenna, preamplifier, and cable

gain/loss can be entered and stored in correction files, and the standard

spurious measurement feature of SignalVu-PC can be used to establish

limit lines for your test. The following illustration shows a test from 30MHz

to 960 MHz against the FCC Part 15 Class A limit shown shaded. The blue

trace is the capture of Ambient. Violations are recorded in the results table

below the graph. CISPR quasi peak and average detectors can be added

with option SVQP.

Analysis of AM and FM signals is standard in SignalVu-PC. The following

screen shot shows a 1 kHz tone amplitude modulating a carrier to 48.9%

total AM. Markers are used on the spectrum display to measure the

modulation sideband at 1 kHz offset, 12.28 dB down from the carrier. The

same signal is simultaneously viewed in the modulation display, showing

AM versus time, with +Peak, -Peak and Total AM measurements.

Advanced measurements for analog audio modulation including SINAD,

THD and modulation rate are available in Option SVA.
