Hi,

Zero span is a very nice and useful feature to check the time occupation of a signal ("signal time on air"), the time to lock of a PLL, the ramp up of a power amplifier, the instant when signal is transmitted, ...

However, for that feature, an accurate horizontal time scale and the possibility to measure the time between events is necessary.

I'm using version 1.7.8 but I didn't find any way to measure the time in zero span mode. What is frustrating is that the instrument already does the job well and display the information but without a mean to measure the time scale.

In future design, the possibility to correlate the amplitude evolution with the state of a simple digital input (TL level is Ok) could be also very useful.

Many thanks in advance for your reply,

Fabrice
