[Test-Equipment] Maconi 2017 and 2022C help needed

[ma yu]

Good evening eveyone, 
I just got two SSGs, Marconi 2017 and 2022C. The 2017's output level is  
very low, for example,indicated 1uV,but actually the output only 0.1uV 
orso,maybe between 520-1040MHz no output .but the LED level meter seems 
OK.The 2022c not output below 250MHz, 250-1GHzis are all OK.Couldsome one 
can help me? Thanks in advance! 
  73!  Hsu
