Stephan, I'm still new at this subject and I'm not an expert, but here's what I've found. The SC-10 oscillator from Stanford Research has this paragraph in the manual:
"The EFC input exhibits a single-pole RC type response with a -3dB point of about 3kHz when driven by a voltage source with an output impedance of 1kohm or less." Also the MTI 250-0799 data sheet indicates a bandwidth of 200 Hz, and the 270-0269 has a stated bandwidth of 400 Hz. I bought a Stanford Research SC-10 directly from the factory about 6 months ago, but now I know I don't have the equipment to really test the stability of this oscillator. Has anyone had a good look at the SC-10 (tvb?).
