Rhode & Schwartz FSIG3 Signal Analyzer

Manufacturer:  Rhode & Schwartz
Model: FSIG3
S/N: 100008/063
Reference No.:  292L

Description: The Rohde & Schwarz FSIG3 3.5 GHz Signal Analyzer provides in a single unit comprehensive and easy-to-use measurement functions in the, frequency domain, time domain, modulation domain and code domain (cdmaOne forward channel). In the frequency domain, the FSIG 3 measures intermodulation and harmonics with great accuracy. The high 3rd-order intercept point in conjunction with the extremely low noise floor yields a wide intermodulation-free dynamic range and ensures reliable performance of even sophisticated measurements like spurious measurements. The maximum input frequency of 3.5 GHz allows even out-of-band spurious measurements. In the time domain, the FSIG 3 features all modern capabilities of burst analysis in TDMA systems; gate functions, trigger delay and integrated RF trigger in conjunction with a short sweep time of 1 µs ensure precise measurement of the timing characteristics of mobile radio systems. In the modulation domain, the integrated vector signal analyzer provides diverse measurements on GSM, EDGE, IS-136, cdmaOne, W-CDMA/ 3GPP signals. These convenient presettings make it superfluous for the user to spend valuable time in looking up specifications and go towards enhancing the measurement reliability. An optional application firmware FSIQ-K71allows power measurement in the 64 Walsh code channels of a cdmaOne signal (forward channel). The results can be output numerically or displayed as a bargraph.
