[Test-Equipment] Tektronix 492B Question

[Mark Donaldson]

I have a Tektronix 492BP spectrum analyzer and was
wondering what distinuishes this model from the 492
and/or the 492A? What options were available for the
492B? What features were standard on the 492B that
were options for the 492, if any? 

Thanks
