3 Press the Serial softkey, turn the Entry knob to select the desired slot
(Serial 1 or Serial 2), and press the softkey again to enable decode.
4
Press the

8 Press the Auto Setup softkey which performs these actions:
• Sets the probe attenuation factor of the input Source channel to 10:1.
• Sets upper and lower thresholds to a voltage value equal to ±1/3
division based on the current V/div setting.
• Turns off trigger noise reject.
• Turns on Serial Decode.
• Sets the trigger type to MIL- 1553.
9 If the upper and lower thresholds are not set correctly by Auto Setup ,
press the Signals softkey to return to the MIL- STD- 1553 Signals Menu.
