Five frequency models. One platform.

Pick the frequency ceiling, then choose a single-channel desktop unit or a 2U rackmount with up to four phase-coherent channels (the -X models).

875-04	10 MHz to 4 GHz	4.15 GHz	Type N (F)
875-06	10 MHz to 6 GHz	6.6 GHz	Type N (F)
875-12	10 MHz to 12 GHz	12 GHz	Type N (F)
875-20	10 MHz to 20 GHz	20 GHz	SMA (F)
875-40	10 MHz to 40 GHz	43.5 GHz	K (2.92 mm) (F)

Specifications reproduced from the Model 875 datasheet (V1.32) as published at berkeleynucleonics.com. Typical values are not warranted performance; PDW, UFS, SYNC, MOD, FCP, and AVIO are options.

Where the 875 goes to work.

Radar signal simulation
each channel can run its own independent PDW simulation, and multiple PDW sequences play back with phase coherence and accurate timing.

EW and receiver testing
up to four coherent emitters from one 2U chassis, with Option SYNC linking multiple units while keeping phase coherence across them.

Avionics modulation emulation
DME, VOR, ILS localizer and glideslope, and marker beacon signals with Option AVIO.

Arbitrary I/Q and antenna testing
play stored I/Q waveforms from memory, or stream I/Q data live through the fast control port (Option FCP) for high-speed antenna and receiver work.
