Complete Wi-Fi 80 MHz Channel Capture: Wi-Fi 5 (802.11ac) and Wi-Fi 6 (802.11ax) support 80 MHz channels as a primary operating mode—it's the bandwidth that delivers the real-world throughput most users experience. At 40 MHz, you can only see half of an 80 MHz channel; at 85 MHz, you capture the entire channel plus 2.5 MHz of margin on each side. That margin matters because spectral mask compliance requires visibility beyond the channel edges. With the B40, you'd need multiple sweeps to characterize an 80 MHz channel. With the B85, it's one real-time capture—including any transient spectral regrowth, modulation anomalies, or spurious emissions that a swept measurement would miss.
5G NR 50–80 MHz Carriers with Adjacent Channel Visibility: A 50 MHz 5G NR carrier occupies roughly 48 MHz of occupied bandwidth. With 85 MHz of real-time coverage, you see the complete carrier plus significant adjacent channel territory—enough for meaningful ACLR screening in real-time. An 80 MHz NR carrier fills the 85 MHz window tightly but is still fully captured. This is the practical minimum bandwidth for engineers working with sub-6 GHz 5G NR carriers that routinely run at 50–80 MHz channel bandwidths in bands n77/n78.
Multi-Carrier LTE Monitoring: At 85 MHz, you can simultaneously observe up to four contiguous 20 MHz LTE carriers—the typical deployment for LTE-Advanced carrier aggregation. This enables real-time monitoring of inter-carrier interference, power balance between carriers, and timing alignment issues that don't appear when measuring carriers individually.
Wideband FMCW Radar Chirp Analysis: FMCW radars used in automotive (24 GHz), industrial level measurement, and surveillance applications employ chirp bandwidths from 40–200+ MHz. The 85 MHz real-time bandwidth enables complete capture of chirps up to 85 MHz—sufficient for many 24 GHz automotive radar systems and industrial radar sensors. You can analyze chirp linearity, spectral purity across the chirp bandwidth, and identify modulation-on-pulse anomalies in a single real-time acquisition.
