Conversion of 500MHz TDS744A to 1GHz TDS784A

nctnico:
How about getting a simple mmic based amplifier?

Jay_Diddy_B:
Hi,

As well as needing high amplitude, the signal needs to be levelled. That is the amplitude needs to  be constant over the frequency range.

You may trouble if you use a MMIC amplifier.

If you use an RF generator you can adjust the amplitude so the output of the MMIC is correct.

EDIT: not only that, but the output is only +7dBm - never mind...

The 8447E is the power amp version, with +12.5dBm output.

And that's not enough either.  :(
