Detailed information
-
The 4957B RF handheld multifunction analyzer integrates measurement modes such as cable and antenna analysis, spectrum analysis, vector network analysis, USB power measurement, and vector voltmeter, making it suitable for a wider range of measurement scenarios.
-
In spectrum analysis mode, it is equipped with one-key integrated test functions such as channel power, occupied bandwidth, adjacent channel power, analog demodulation, interference map, spurious mask, carrier-to-noise ratio, IQ capture, and audio monitoring. This is useful for solving more field test issues.
-
The vector network analyzer adopts a two-port measurement and provides standard S-parameter vector network analysis functions, as well as measurement capabilities such as time domain measurements, multi-measurement formats, and multi-window measurements. It can be used for S-parameter testing of amplifiers, filters, attenuators, and duplex components. It is particularly useful for external field measurements of antennas, connectors, cables, and more.
-
The frequency range of the 4957B RF spectrum analyzer is 9kHz to 6.5GHz, with a possible DANL of -140dBm, which can reach -160dBm when the preamplifier is turned on, and the phase noise is better than -112dBc/Hz @ 100kHz. This functionality effectively ensures the ability to test weak signals. <Excellent phase noise performance>
