Function Generator output not lower than 3mV

Post by mike0811 »

Hi,

I bought recently a 2205A. I want to feed 500uV 1Khz Sine to my MC Phono Preamp to measure SNR. Its all silent. Only when I step up to 3mV, the 1Khz Signal is output. When I step down to 2mV - silent.

So a low output cartridge generates around 0.5mV @ 1Khz.

In the Spec its written:
Output voltage range ±2 V

Also what I recognized, feeding directly from the generator, the SNR is so bad, around 38dbu. Is this to expect from the scope?
Thanks,

Mike
