Anritsu   The MS2681A/MS2683A/MS2687B Spectrum Analyzer has been designed to provide the optimum performance required for evaluation of the advanced radio communication devices. They have a wide dynamic range, wide resolution bandwidth (20 MHz), and high-speed sweep (refresh rate: 20 times/s). When measurement software is stalled in the mainframe, the analysis function of spectrum analyzer to each communication system will be extended. In this case, more advanced analysis can be performed.KEY FEATURES: *Frequency range: 9 kHz to 3.0 GHz (MS2681A) and 9 kHz to 7.8 GHz (MS2683A) *Wide resolution bandwidth up to 20 MHz *Data transmission speed approximately 10 times faster (GPIB transmission speed: 120 KBytes/s) *Optional measurement software (sold separately) for high-speed modulation analysis (1.5 sec. with W-CDMA, 0.5 sec. with IEEE 802.11a) *Optional narrow resolution bandwidth from 1 Hz * Low average noise level (-146 dBm/Hz, 1 MHz to 3.2 GHz) * High-speed sweep (20 times/s) See Spec
