The Anritsu MS2691A is a dual-function signal analyzer and generator spanning 50 Hz to 13.5 GHz, engineered for vector and spectrum analysis in R&D and high-speed manufacturing test environments. With Option 020 installed, this system adds signal generation capability from 125 MHz to 6 GHz with 120 MHz vector modulation bandwidth and 256 Msample waveform memory. The analyzer delivers 177 dB dynamic range, –155 dBm/Hz DANL (30 MHz to 2.4 GHz), and ±0.5 dB absolute amplitude accuracy across a 6 GHz span, supporting LTE/LTE-Advanced, 5G NR sub-6 GHz, WLAN 802.11ac, GSM, W-CDMA, and Mobile WiMAX modulation formats. Resolution bandwidth ranges from 30 Hz to 31.25 MHz in spectrum analysis mode and 1 Hz to 10 MHz in signal analysis mode. Standard analysis bandwidth is 31.25 MHz with optional 62.5 MHz and 125 MHz configurations available.
