The R&S FSH3.23 3 GHz Handheld Spectrum Analyzer is ideal for rapid, high-precision, cost-effective signal investigations. It provides a large number of measurement functions and so can handle anything from the installation or maintenance of a mobile radio base station up to on-site fault location in RF cables as well as development and service – an extensive range of applications. The R&S FSH3.23 comes with an adjustable preamplifier, making it suitable for measuring very small signals. With it's internal tracking generator it can be used for distance-to-fault (DTF) measurements, scalar and vector network analysis, and one-port cable loss measurement. By means of the TDMA POWER function, the FSH3 performs time-domain power measurements within a timeslot of TDMA (time division multiple access) methods. Specifications. Frequency range: 100 kHz to 3 GHz. Resolution: 1 Hz. Counter accuracy: S/N > 25 dB ± (frequency × reference frequency error). Resolution bandwidths: 100, 300 Hz, 1, 3, 10, 30, 100, 200, 300 kHz, 1 MHz. Video bandwidths: 10 Hz to 1 MHz. Displayed average noise level: typ. –135 dBm (100 Hz). TOI: typ. 13 dBm. SSB phase noise: <–100 dBc (1 Hz) at 100 kHz from carrier. Detectors: sample, max/min peak, auto peak, RMS. Level measurement uncertainty: <1.5 dB, typ. 0.5 dB. Reference level: –80 dBm to +20 dBm. Interfaces: RS-232-C optical interface. Options. FSH-B1 (1145.5750.02), Distance-to-Fault Measurement. FSH-K1 (1157.3458.02), Remote Control via RS-232-C.
