Description

The BNC Model 845 is a low-noise and fast-switching microwave signal generator covering a frequency range from 100 kHz up to (3, 6 12, 20) 26 GHz+. The lowest settable frequency is however as low as 100 kHz with some reduced maximum output power. The BNC Model 845 a wide and accurately levelled output power range and high spurious uppression. Advanced frequency synthesis with fractional-N divider makes for low SSB phase noise and micro-Hz frequency resolution. 

Power level extension is available to accurately level down to -90 dBm.

The BNC Model 845 includes AM, DC-coupled, low distortion wideband-FM, PM, FSK and PSK, frequency chirp, and fast pulse modulation with internal pulse train generator as standard. Three internal modulations sources are available. All modulation modes of the BNC Model 845 can be combined. This allows the generation of complex modulation signals for modern communication and location systems. The combination of pulse modulation and FM simulates Doppler effects or chirp signals. Simultaneous AM and pulse modulation provides the types of signal occurring in pulse radar applications with rotating antenna. The combination of FM and AM can be used to check fading effects of FM receivers.

The BNC Model 845 allows fast analog and digital sweeps including flexible list sweeps, where frequency, power and dwell times can be set individually. A flexible triggering capability simplifies synchronization within test environments. The BNC Model 845 operates with an ultra-stable temperature compensated 100 MHz reference (OCXO) to ensure minimal drift, and can be phase-locked to any stable external reference in a range from 1 to 200 MHz. Additionally, optimum phase synchronous signals can be achieved by feeding a 100 MHz reference directly as reference.

The BNC Model 845 support various standard interfaces such as USB-TMC, LAN, and GPIB. It is targeted for applications where a high-quality CW microwave source with versatile modulation is required. It offers an alternative to expensive high-end microwave signal generators, where small size and excellent microwave performance at an attractive cost is required.
