To achieve characteristic performance:

Requires 86100A or B with 86100A software revision 3.0 or above.

For the 86107A with option 020, the Agilent 11742A (DC Block) is recommended if the DC offset magnitude is greater than 200 mV.

The freerun trigger mode internally generates an asynchronous trigger that allows viewing the sampled signal amplitude without an external trigger signal but provides no timing information. Freerun is useful in

troubleshooting external trigger problems.

The sampled input signal timing is recreated by using an externally supplied trigger signal that is synchronous with the sampled signal input.

The DC to 100 MHz mode is used to minimize the effect of high frequency signals or noise on a low frequency trigger signal.

Measured at 2.5 GHz with the triggering level adjusted for optimum trigger.

High Sensitivity Hysteresis Mode improves the high frequency trigger sensitivity but is not recommended when using noisy, low frequency signals that may result in false triggers without normal hysteresis enabled.
