Siglent SDS1000X HD versus SDS2000X HD

Electro Fan:
Just for grins, what do you get when you set it for 9,999,999 Hz on the dot? Thx

Maybe later I can connect it to AWG and see. This was just 10 MHz OCXO..

The point is that last digit is 1ppm.
Time base Accuracy ±2 ppm initial (0~50℃); ±0.5 ppm 1st year aging; ±3 ppm 20-year aging..

So we are at 0ppm initial and <1ppm for aging in 2 years. For instance.
Or, <1ppm initial error and 0ppm aging.
Or <0.5ppm initial and <0.5ppm aging in 2 years..

So definitely in spec.

Electro Fan:
Any other users with a 2000X HD and an accurate frequency generator up for seeing what the counter says with a 9,999,999.0 Hz input signal? Thx

Not exactly what you asked, but ...............

My 2000HD is only 1.5 months old with very little use so far (single digit hours).  When I feed it a 9 999 999 Hz signal from an SDG2042X that is using a GPSDO external reference, the scope's frequency counter is showing 10.00000MHz.

When I adjust the frequency down 1Hz at a time, the scope's frequency counter changes briefly but then settles back to 10.00000MHz.  Once I hit 9 999 994Hz on the source, the scope's frequency counter finally ends up settling to a value of 9.99998MHz.

Adjusting the frequency up 1Hz at a time, the scope's frequency counter shows 10.00001MHz when the source is set to 10 000 001Hz, but then stays there until the source reaches 10 000 012Hz, at which point the scope shows a reading of 10.00002MHz.

I hope that helps.
