Setup
and
Procedure
1) Select function
De,
amplitude 10 Vp-p.
2) Turn the Sum Input on and inject a 600 Hz,
10 Vp-p sine wave from a 0

source.
Measure
the

according to the following table.
3) Inject a 5 MHz, 10 Vp-p square wave from a
50n
source.
The
square
wave should have rise/faIl times less than 6 ns and aberrations
< 3%
4) Measure the rise/faIl time
and
aberrations
of
the signal
at
the main out
according to the following table:
