INPUT
SIGNAL
The maximum input signal amplitude
(
at
0
dB Gain
)
is specified as ±10 Volts
(7.1
V rms
)
up to a frequency of 300
KHz.
This is the signal amplitude
which can be handled linearly by the instrument. Above
300 KHz
the input
signal handling capability is reduced as shown in Fig. 2-2. The reduction is
due to Siew-Rate* limitations of the Operational Amplifiers employed in the
instrument.
When 20 dB GClin
is employed, the maximum input signal amplitude is ±1 .0
Volt (0,71
V rms
)
up to
300 K Hz.

Input signals in

follow fast changes in input signal and it is usually expressed in volts
