Function Generator Pulse delay this is special function.
Large delay times are very useful too.
In modern AWG you may select for example just one cycle of sine-wave this be output-ed according your choice speaking of repeat-ability.
You have also choices of frequency and amplitude, but in my experiments I did select 400Hz as test frequency at 20V pp.
Accuracy of measurements bellow this is not of high importance.
When a manufacturer does a choice using Hz as signal delay, everything makes sense when we use 1 Hz and above.
Bellow I am going to add measurements lower than 1Hz so most of you to discover the relation of micro Hertz with seconds or milliseconds of time.
Lets start with known values first:
10 Hz = 100ms
9 = 110
8 = 125
7 = 143
6 = 166
5 Hz = 200ms
4 = 250ms
3 = 333
2 = 500
1 HZ = 1 S
Bellow 1Hz Area
900 mHz = 1.11 S
800 = 1.25
700 = 1.43
600 = 1.67
500 = 2 S
400 = 2.5
300 = 3.3
200 = 5.0
100 mHz = 10 S
50 mHz = 20 S
25 mHz = 40 S
I did use my oscilloscope for all those measurements.
If you are interested to discover how bling your oscilloscope this could be at not repeatable signals, then by delivering just one cycle of a signal every few seconds, then you may easily start a comparison ( benchmark ) between two oscilloscopes against its other.
In a such a benchmark, you will gain awareness of how much sampling memory required from your own Oscilloscope so this to become fast enough to capture non repeatable signals.
One another conclusion that you might come to ( subject of personal experience), this is sine-wave frequency and signal amplitude that your Oscilloscope will not capture due their own hardware limitations.
One of my very own conclusions this is that blind time that one Oscilloscope will have regarding signal acquisition, this is not improved by a double in bandwidth Oscilloscope.
I can also reverse my words for a better understanding, one oscilloscope this made to be a high performer, this will have improved signal acquisition even if you choose a model of low bandwidth.
