I'm not sure if the precise model is still being built, but I have been very happy for over ten years with my Wayne Kerr - Farnell PSG1000, which covers 10 kHz to 1 GHz, around $5K, I believe, with 10 dBm maximum output. It has built-in amplitude and frequency modulation, and a modulation port for external sources. I have put a square wave into it before for MIL-STD-461E pulse modulation, but you are really amplitude modulating the waveform. That is, true pulse modulation acts like a switch in series with the rf output, whereas amplitude modulation increases the peak amplitude, and you have to account for that. On the other hand, it is hard to find signal sources down to 10 kHz with pulse modulation capability.

I want the station to perform CS114, DO 160 Section 20 and also EN 61000-4-6 I'm looking for a sig gen that can source a signal from 10 kHz to 400 MHz, and be capable of both AM and Pulse modulation. Anyone care to share their opinion on makes and models. Off line is fine. Right now, I'm tending to an R&S SMY02, but with a 2 GHz top end, it seems overkill. Thanks, and seasons greetings to all!
