EFT/ Burst Generator PEFT Junior 

17 

4.2.1 Control unit P90 

The PEFT Junior is controlled by a microprocessor control unit. The processor ( 8085 ), monitors 
generator functions, reads the keypad, sends information to the display, controls test parameters 
and facilitates the storing and recall of test sequences. The user enters all commands from the 
front panel. Main components of the front panel are an LCD display (1) a numerical keypad (11) 
and the function keys (9).
