Hi Punchinello,

Your hedged question belies an ignorance of premium equipment that has
been dominant in the field for 50 years. How is it you fail to
recommend what you use?

I have calibrated such in a Primary Electronic Standards Lab against
standards traceable to NBS at the time. [but you knew this already]
I did such work under contracts to Boeing, and the model I own was
acquired from Boeing complete with certificates of traceability(not my
own work, I have only on occasion found a piece of precision gear with
my stickers on it).

I have never encountered a GR 1606 that fell outside of its
specifications - except for one where someone apparently burnt out one
bridge component, a resistor. Undoubtedly this was accomplished by
applying a transmitter to the excitation port - one can only imagine
the fate of equipment connected to the detector port. This was very
simple to recover from (one resistor). The instrument is robust and
built like a Swiss precision watch. There are very few things that
could go wrong and only under physical duress (like dropping it down
three floors of stairs).
