8560e spectrum analyzer ERR 335 356

I have 8560ec spectrum analyzer (30KHz to 2.9GHz). I am getting two errors:

1- ERR 335 SMP UNLK

2- ERR 356 SPAC CAL

Also I noticed when the spectrum analyzer doesn't work properly immediately after turning on. For example, when I turn on the spectrum analyzer and connecting the reference signal (300MHz -10dB), for almost 5 minutes SA doesn't show any signal. After 5 minutes the reference signal gradually appears on the screen (with wrong amplitude -17dB) and then after 10 minutes it almost shows an acceptable amplitude for the reference signal (-10.5dB)

 

any help?
