Tektronix 2247A

Basic Applications
Some features of the CH 1/CH 2 Voltmeter function are:
a.
Measures
CH
1
or
CH
2
while
viewing
either
channel.
(Select
the
measurement
source
channel
using
the
SET
MEAS'MT
CHANNEL
menu.)
b.
Measures
signal
levels
(DC
values
and
peaks)
In
SGL
SEQ
(single-
sequence)
Trigger
MODE
continuously.
(Use
CONFIGURE
function
In
the
Service
Menu
to
get
menus
and
readouts
to
remain
on
between single sequence triggers.)
c.
Finds
peaks
of
signal
applied,
not only
just
the
displayed
portions
of
the waveform.
d.
Defines
a
portion
of
the
waveform
(GATED
measurements—
especially
useful
for
making
measurements
on
a
multi-level
signal)
on
which
to
make
the
selected
measurement.
(Use
page
2
of
the
VOLTMETER menu to select a GATED-measurement mode.)
NOTE
Very narrow-gated measurements at 20 ns per div sweep
speed are impractical due to imprecise definition of the
intensified zone at that sweep speed.
Peak Voltage Measurement
To make a +peak voltage measurement use the following procedure:
1. Apply the signal to be measured to CH 1 Input connector.
2. Set:
VERTICAL MODE CH1
Horizontal MODE A
3. Press AUTO SETUP button.
4, Press the VOLTMETER CH1/CH2 button to call up the selection menu
and select the +PEAK choice. Any of the page one cholces may be
selected as required for the waveform measurement wanted.
Depending on the way the CONFIGURE cholces of the SERVICE menu
have been made, the menu will either go off when the measurement
selection Is made or It will stay on. If the menu remains on, press the
CLEAR DISPLAY button once to remove it from the display. See the
SERVICE Menu discussion in Section 3 for further details.
