If you use TWO of SV1AFN¡¯s attenuators in series (31 dB per PE4306 attenuator), you get 62dB total.? You don¡¯t need to buy his controller¡­ you can control it via the Arduino SPI interface.

Would it be more useful to build in two attenuators in the front end (60db)?

If you have the space and the money, yes
In practice I have not found much use for 60dB as for high power input signals you should want a high power attenuator and the PE4302 is not capable to do this
