Having both RF and True RMS makes it a bit special. Usually you can have one but not both. My VTVM works to 150 MHz, but either measures peak or assumed sinewave for RMS voltages.
I've a DVM that does true RMS, but I doubt even up to the limit of audio.
My spectrum analyser can measure μV up to 1.5 GHz, but not true RMS. Peak and maybe something called "Average RMS". Can do zero span.
I've also a digital scope (with missing logic analyser pod) that can measure , but only peak and average up to 100 MHz, so less good than the old VTVM.
