Microprocessor Control
The bold arrows in Fig.
1-2 indicate microprocessor control path in the
VP-7721A.
Benefits from the use of a microprocessor are described
later.
One inconvenience was the interference that might be caused by
clock signals, which the VP-7721A has successfully overcome by ceasing
clock signals during measurement.

Floating Input
The input terminals of the measurement section in the VP-772LA can be
arranged for both floating and non-floating connection.
The floating
connection permits measurement of amplifiers with floating output
configuration such as so-called BTL
(balanced, transformer-less)
type
amplifier.
