Vrms Vpp Vmax - Can DSO068 also show these measurements?

[rtek]

The DSO150 can display measurements such as frequency, Vpp, Vmax, Vmin, Vrms.

Can DSO068 also show these measurements?

I have a DSO150, but unfortunately I need to read a 450kHz signal, and display the Vpp, Vmax, Vrms values.

Would it be possible to adapt the hardware of the DSO150 to operate with the TLC5510?

I ask this because the DSO068's display looks pretty old-fashioned.
