The R&S SMP04 (1035.5005.04) 40 GHz Microwave Signal Generator has been designed for high output power with AM, FM and optional phase modulation. High spectral purity is ensured by the use of YIG oscillators – up to 20 GHz without any frequency multiplying. The crystal reference built-in as standard ensures an accurate and low-drift output frequency. The SMP04 has extremely low SSB phase noise of <–105 dBc/Hz at 10 GHz (10 kHz from carrier) as well as nonharmonics of <–60/54 dBc up to/above 20 GHz. Functions qualifying the SMP04 for EMC applications include the trigger facility for step-by-step sweeping, marker outputs and, above all, the extension of the frequency range to 10 MHz (option SMP-B11). Specifications. Frequency Range: 2 GHz to 40 GHz. Resolution: 0.1 Hz. Setting time (to within <1x10^–6) after IEC-/IEEE-bus delimiter: <(11 ms + 5 ms/GHz). Phase offset: adjustable in 1° steps. Harmonics f <1.8 GHz: <–30 dBc (<+0 dBm). Nonharmonics at >10 kHz from carrier f <2 GHz: <–60 dBc typ. Maximum level: >+12 dBm (10MHz to <2GHz), >+10 dBm (2 GHz to <18 GHz), >+6 dBm (18 GHz to 20 GHz), >+11 dBm (20 GHz to 33 GHz), >+10 dBm (33 GHz to 40 GHz). Resolution: 0.1 dB or 0.01 dB. Output impedance: 50 ohm. Remote control: IEC625 (IEEE488). Options. SMP-B11 (1036.6240.02), Frequency Extension 0.01 GHz to 2 GHz. SMP-B12 (1036.5750.04), Pulse Modulator 2 GHz to 40 GHz.
