I have signal generator hmc t-2220. After 6 months of use it generated signal has limit power -20dbm. After the occurrence of the problem Generator on loading write on display "HMC-T2100".
HW ver 5.3
SW ver 2.5
Pesumably the problem is the failure of the microcontroller firmware. Information is needed on pin-connector sockets RS-232 and standard data for update microcontroller firmware. Please share the information about RS-232 on HMC-T2220.
Thanks in advance!
