Operation
and
Reference
Amplitude
The
[Amptd]
(amplitude)
key
enables
display,
entry,
or
modification
of
the
mnplitude
of
the
signal
output.
The
indicator
adjacent
to
the
[Amptd]
key
illuminates
when
an
amplitude
value
is
displayed.
The
displayed
amplitude
value
is
changed
with
the
numeric
keypad
and
units
keys,
or
modified
with
the
Modify
keys.
The
Volt,
V
RMS,
mV
RMS,
and
dBm
units
allow
convenient
entry
of
amplitude
values.
Amplitude
values
are
displayed
in
Volts
rms,
Volts
peak-to-peak
(Vp;p),
or
dBm
as
denoted
by
the
indicators
at
the
right
of
the
display.
The
amplitude
range
is
dependent
upon
selection
of
dc
offset
and
the
high
voltage
option
(see
table
1-6).
The
output
signal
is
momentarily
set
at
zero
volts
when
internal
attenuator
settings
change.
The
HP
3325B
units
keys
convert
amplitude
values
to
Vpp,
Vrms.
or
dBm
for
any
function.
For
example,
if
a
sine
wave
amplitude
of
10
Vpp
is
displayed,
pressing
the
[Vrmsl
or
[mVrmsl
key
displays
the
same
amplitude
as
3.536
Vr
ma
,
while
pressing
the
[dBm]
key
displays
the
value
as
23.98
dBm.
When
changing
from
one
function
to
another,
the
last
amplitude
displayed
is
held
constant.
