Compatibility & Integration BenchVue software (BV0007B Power Meter/Sensor Control and Analysis app) provides intuitive control, data logging, and visualization without programming. Instrument drivers support LabVIEW, LabWindows/CVI, and Measurement Studio. The sensor integrates with Keysight network analyzers (ENA, PNA, PNA-L, PNA-X, PXI VNA, PXIe Multiport VNA, FieldFox) for source power calibration. Built-in presets for DME, GSM, EDGE, WCDMA, WLAN, and LTE signals accelerate deployment. Firmware updates available via Keysight Firmware Upgrade Utility.
