Here comes an interesting information from the mouth of GW Instek.
While an probe at 10X, it lowest rise time this expected to be at it speechified bandwidth.
At 1X, it rise time this is limited at 58ns, after conversion to frequency, this is approximately17.24 MHz
The rise time for all our probes is 58ns for X1 probe attenuation.
Rise time this is only the first of critical parameters.
The second this is probe loading.
There is a good reason, that all function generators they do not deliver output above the 7V limit.
One cable with BNC connectors alone, an X1 type of connection, the limited 7V output by the AWG, this is unable to overdrive scope 10V ADC input. ;)
From the other hand, RG58 cable with BNC connectors, this has lossless bandwidth up to 400MHz.
This is by far superior than any probe at X1.
In conclusion:
The best advice for using a probe at X1, this is when the signal this at 5V or lower, and at 15MHz as Max.
