Setting gain and frequency on active crossover

I’m using the hps140 to set the gain on my active crossover as I’m playing a 1khz at 0db but I encounter an issue that the hps140 can’t trigger while I’m tapping on the crossover output.
What might be the issue any guidance?

We’re sorry, but this information does not allow us to be of any assistance.
Please elaborate on the problem and please provide signal specs such as level, etc…
Also, what are the scope settings?

Thanks for your respond.
I’m trying to set the gain on my active crossover and I can’t seem to get the scope trigger.
The scope was set to auto trigger.

Input signal frequency?
Level?
Scope set to AC or DC coupling?

Does the scope work fine with other signals? DC measurement?
