AC peak voltage measurement with 3458a

Hi,

 

I'm trying to measure a sinusoidal signal which is having an amplitue of 2 V and variant frequencies between 10 Hz ~ 300 Hz. I've tried "PRESET DIG" configuration and I was unable to get a waveform similar to sine wave. Then I tried "PRESET DIG" configuration again and then send "TIMER 0.01" command and frequency of the signal is 10 Hz. As far as I understood from the statements in user's guide, by sending "TIMER 0.01" command, I expect sampling rate to be 100 Hz. In this case, I expect to have at least one cycle of 10 Hz sine wave but I don't have it and I can't see at which part I'm wrong.

 

I've attached a screenshot of a portion of the graph I have. Any help will be appreciated.

 

Thanks in advance,

Emre
