Unlike other sellers, this set is ready to use right out of the box with FRESH BATTERIES (the factory original ones won't last at this age) and POWER SUPPLY (this model's power supply is wired differently and is picky about connectors so it's hard to find an aftermarket unit that'd work without modifications).

The pictures shows some frequency points to show the unit is spot on. I tested the end frequency ranges with my 83752B sweep generator at -10dB (without preamplifier) and the frequency points in between at -70dB (with pre-amplfier on) and they are spot on. 

This is the option .03 model (with Preamplifier)

Range: 100kHz to 3Ghz
RBW: 100Hz to 1Mhz 
VBW: 10Hz to 1Mhz
DANL: typical -135dBm
TOI: typ 13dBm
SSB phase noise: <-100dBc (1Hz) at 100kHz from carrier
Level measurement uncertainty: <1.5dB, typical 0.5dB
Reference level: -80dBm to +20dBm

I have a working reserve unit for parts to service this unit (just the plastic shells and acrylic screen protector are broken), so I can offer a 1 year warranty with the parts as hedge.
