A calibration signal and the following additional signals can be output
through the connector labeled AUX OUT on your oscilloscope. Use the
Auxiliary Output to send the following signals to other instruments:

Trigger Enabled - This function can be used as a gating function to
trigger another instrument when the oscilloscope is ready.

Trigger Out - This function can be used to trigger an external
oscilloscope.

Pass/Fail - Allows you to set a pulse duration (varied based on your
specific model, refer to specifications at teledynelecroy.com for
details); generates a pulse when pass/fail testing is active and
conditions are met.

Fast Edge - Some models provide this signal output used to deskew
multiple channels. The Fast Edge connection varies based on model
and is either SMA or BNC.
