Measuring Third Order Intercept With The R S Fpc Youtube This video shows how to configure a rohde and schwarz fpc series spectrum analyzer to make third order intercept measurements.learn more about the r&s fpc: h. R&s®fpc k7 modulation analysis. the specifications below apply to the r&s®fpc1000 and r&s®fpc1500. they are based on the data sheet specifications of the r&s®fpc1000 and r&s®fpc1500, have not been checked separately and are not verified during instrument calibration. measurement of analog modulation signals.
Understanding Third Order Intercept Youtube The rohde and schwarz fpc1500 (order # 1328.6660.03) is a spectrum analyzer with frequency range of 5khz 1ghz, a tracking generator and built in vswr bridge. the fpc1500 is easily upgraded via software keycode with a variety of options including a preamplifier, vector reflection measurement, modulation analysis and much more. Demodulation for am fm ask fsk is available with software option fpc k42. a vaguely named “advanced measurement” option, fpc k55, adds a spectrogram, channel power, third order intercept (toi), harmonic distortion, tdma power, and am modulation depth. fpc k43 adds channel scanning and emi pre compliance. The r&s®fpc has the largest, highest resolution display of any entry level spectrum analyzer. more horizontal plus more vertical display size and resolution means more signal details in unprecedented clarity. this top class r&s®fpc display visualizes the outstanding signal measurement quality. Intermodulation free dynamic range. clearly, the 3rd order intermodulation tones have the same spacing to the upper and lower tone as the two original tones have (Δf). Δf Δf Δf p im3 p tone pΔ figure 1: two tone scenario used for imd testing additionally, the so called third order intercept point (ip3) can be calculated. it is a.

The toi measurement is made by combining two fundamental tones at frequencies ω 1 and ω 2 and measuring the relative level of the two third order distortion products at frequencies 2ω 1 ω 2 and 2ω 2 ω 1. as the amplitude of the fundamentals is increased by 1 db, the absolute level of the third order distortion products increases by 3 db. Third order intercept (toi) frequency: 1 ghz typ. 15 dbm phase noise frequency: 500 mhz 30 khz carrier offset < –95 dbc (1 hz) 100 khz carrier offset < –100 dbc (1 hz) 1 mhz carrier offset < –120 dbc (1 hz) detectors sample, max. peak min. peak, auto peak, rms total measurement uncertainty rf attenuation: auto.
