Input and Outputs

The Agilent 81133A/81134A pulse generator provides the following

inputs and outputs:

Channel Specific Inputs and O utputs For each channel:

•One Delay Control Input to apply an external signal for jitter

modulation.

For more information, see “Jitter Modulation” on page 83.

• One normal and one inverted Output for the generated signal

Global Inputs and Output s For the i nstrume nt:

•Clock Input

The clock input is used to apply an external clock signal or a

reference signal for the internal PLL if a higher frequency accuracy

than 50ppm is required.

This inpu t can be AC or DC ter minated . If it is D C is ter minated, the

termination voltage can be set.

For more information, see “Clock Sources” on page 73.

•Start Input

The st art i nput is used t o star t the instr ument on an e xtern al sig nal.

For more information, see “Start Mode” on page 75.

• Trigger Output

The trigger output can be used to trigger another instrument.

For more information, see “Trigger Out” on page 75.
