So it seems to be.

I consider their way of specifying the instrument misleading. The value of 60MHz is not only mentioned in the sine wave specification, but in the general, or global, specification as well. For any other machine, that would mean the bandwidth of the instrument. In addition to that, set to 60 MHz sine, it achieves a rise time of 6 ns!

You're right, that with the spec of 16 ns rise time for square wave, with a little math it follows that the waveform cannot deviate from sine much anymore at 20 MHz. But, when I read a data sheet, do I have to perform all kinds of calculations to find out if what I read is actually consistent? If a rise time of 16 ns is consistent with what I read as a globally specified bandwidth of 60 MHz? Because only if I find out it is not, I would question if I interpreted everything correctly.

I may send the unit back, as it probably does not satisfy my (current) needs, while a 60 MHz device would have. Not sure if I'll buy UNI-T devices so easily again.

Cheers  Peter

No promises but if you wait 24 hours I may be able to post some photo(s) of pulses from my 962. May help you decide if yours is actually faulty or within dubious spec.

wasedadoc:
10 MHz square wave from UTG-962E into 50 Ohm load.

wasedadoc:
10 MHZ square wave from UTG-962E into TinySA.  Span 0 to 60 MHz.

10 MHz fundamental. 30 MHz and 50 MHz harmonics.

Apologies.  My previous answer was incorrect.  Instead of relying on my memory I've dug mine out and turned it on.  No dBm options.

My original answer from memory was correct.  It does offer dBm setting.
