Rogol 1054Z actual bandwidth

rad400:
When a Rigol DS1054Z 50Mhz scope is updated to a 100Mhz, do you really get an improvement in the bandwidth?.   At 100MHZ are you down only 3db or considerably more?
MarkF:
The 3dB bandwidth for the DS1104Z 100MHz scope is approx 160Mhz.
The 3dB bandwidth for the DS1074Z 75MHz scope is approx 90Mhz.

You need to watch Dave's video on the subject.  There are two filters on the front end of each channel.  One for 50 MHz bandwidth and one for 100 MHz bandwidth.  The choice is made by the firmware.  If it thinks it is a 50 MHz scope, it chooses the 50 MHz filter.  If it thinks is is a 100 MHz scope it chooses the 100 MHz filter.  That's why tweaking the scope settings make a difference.

Set to 100 MHz, the scope has been tested and found to have rather more than 100 MHz of bandwidth to -3 dB.  I don't recall the number but it's up around 150 MHz.

1054Z hacked go far away from 100 Mhz, at least 130 Mhz without attenuation, and +- 200 Mhz with attenuation

Yes.

The 3dB point is usually around 130MHz (as measured by several people here).
