The Model 875 is an ultra fast-switching vector modulated signal source covering a continuous frequency range with models from 10 MHz to 40 GHz. The Model 875 offers switching speeds down to 200ns, enables ultrafast CW frequency sweeps, chirping, intra-pulse modulation and pulse shaping with very low phase noise. A high performance internal I/Q modulator enables customized modulation waveforms and supports dedicated modulation schemes such as avionics modulations. The new design offers deep memory and such wideband capability, complex modulation is now affordable. 
 
The 875 is an ultra-fast-switching vector-modulated signal generator series covering a continuous frequency ranges from 10 MHz to 4, 6, 12, 20, or 40 GHz, respectively, with 0.001 Hz resolution, and 400 MHz RF modulation bandwidth. The 875-X-X is the corresponding multi-channel product series. A high performance internal I/Q modulator enables customized waveforms as modulation signals and supports variety of modulation schemes including avionics modulation. The internal dual channel arbitrary waveform generator fitted ensures carrier suppression of >80 dB and image suppression of >75 dB. The standard 875 enables ultra-fast CW frequency sweeping, chirping, intra-pulse modulation, pulse shaping with very low phase noise. Among others, the following use cases are supported: • Upload multiple formats of IQ Data into 875 Memory. An 875 GUI supports data formats from various vendors. The internal RAM can store up to 512 MS (32 bits per I/Q sample) of IQ data. The 875 internal AWG can play selected sections of the RAM upon a user trigger. • Use 875 to synthesize and play predefined digital modulation formats (option IVM) • Use the analog I/Q inputs (option AIQ) with up to 250 MHz analog bandwidth. • Use FCP interface (option FCP) to: - live stream digital I/Q data. - instantaneously switch between pre-loaded I/Q data segments. - control for ultra-fast frequency hopping (additionally, option UFS required). All 875s operate with an ultra-stable temperature compensated frequency reference (OCXO) that can be phase-locked to an external reference. The compact unit allows for full front panel control via touch panel display, and PC GUI Software supported operation via ETHERNET, USB, FCP and GPIB communication ports.
