Reconnect the DUT Enable the outputs:

Auxiliary Settings for Start Input and

Trigger Output

To set the start input and trigger output parameters:

1Switch to the Aux page.

2In the Start Input panel, set:

–The start mode to Ext. Inpu t.

This automatically puts the instrument in “armed” mode. This is

indicated by the activated Armed softkey function.

“Armed” mode means that the signal is output as soon as the

specified external signal occurs at the start input.

NOTE In burst mode, the “armed” mode is deac tivated as soon as the

specified burst has been ou tput.

To put the instrument in “armed ” mode again, press the Armed

softkey function.

–Start on the Rising edge.

– The threshold t o 500 mV.

3In the Trigger Output panel:

– Select the trigger m ode Pulse.

The frequency of the trigger output equa ls the frequency as

specified in the instru ment panel.

– Set Ampl to 2 V.

– Set Offset to 0 V.

– Enable the trigger output.
