Trigger Output
You can select one of the following signals to be output at the TRIG OUT
connector on the rear panel of the oscilloscope:
• Triggers
• Source frequency
• Source frequency/8
• Mask test pass/fail (see
Triggers
This is the default selection. In this mode, a rising edge is output each time the
oscilloscope triggers. This rising edge is delayed 17 ns from the oscilloscope's
trigger point. The output level is 0-5 V into an open circuit, and 0-2.5 V into 50 Ω.
Source Frequency
This mode is only available when the oscilloscope is set to positive or negative
edge trigger on a front-panel source (analog channel). In this mode, the TRIG OUT
BNC is connected to the output of the trigger comparator. The output level is
0-580 mV into an open circuit, and 0-290 mV into 50 Ω. The maximum frequency
output is 350 MHz due to the bandwidth limitation of the TRIG OUT BNC
amplifier. This selection is useful for driving an external frequency counter.
Source Frequency/8
This selection produces the same signal as described in Source frequency except
the output frequency is one-eighth of the trigger comparator output frequency.
This mode is useful when your input signal is faster than 350 MHz.
The Trigger Out connector also provides the User Cal signal. See
