HP33120A Incorrect Output Amplitude

Hi,
I am having problem with HP33120A function generator. The problem is the output amplitude.  I set it to sine wave, 100mVpp, at 1kHz. I use 50 ohms coax cable and the oscilloscope to examine the output of the function generator. The oscilloscope display sine wave with amplitude 680mVpp  at 1kHz. To be correct, the output should be less than 240mVpp sine wave at 1kHz. I try to set it to factory setting (100mVpp, sine wave at 1kHz) but it still give 680mVpp. Please help if anyone have encounter and solve this problem. Thanks in advance.
