And I quote:

The VA62 consists of five general parts:
1) The video pattern generator
2) The microprocessor-controlled RF-IF generator
3) The drive signal generator
4) The digital meter
5) Special analyzing tests
All are part of a single, self contained unit.

Features:

Cable channels from 2 to 99
Special video patterns and all channel RF coverage to test any tuner
Phase locked drive signals
Injection signals for video, chroma, sync, horizontal output, vertical driver and output, keyed stages and audio stages from IF to speaker
Reliable yoke and flyback tests
VCR analysis
RGB analysis
MTS analysis
Upgradeable with the following accessories (sold separately):
VC63 Test Accessory, NT64 NTSC Pattern Generator, ST65
Video Analyzer Stereo TV Adder and RG67 NTSC Video Monitor Adaptor
----------------------------------------------------------------------

They claim it can detect a single shorted winding in the yoke by using a ringing test. Pretty lah dee dah if you ask me. Am sure it's beyond overkill, but if I were to buy all the testers to do the job of this one unit then I'd easily spend more than $200 so it does make sense, for me anyway.
