Another nested loop is opened:

This loop runs until a trigger condition is

the loop calls Handle_Keypresses, which

looks for commands that the user may have

entered on the keyboard via the terminal

emulator, and Handle_Switches, which looks

for user input from the front panel switches.

These cycle through the timing ranges, the

The code then calls Get_Samples, which

acquires enough signal values to span two
