Preparation For Use - 2236 Operators
34 VAR HOLDOFF Control Provides continuous con
trol of holdoff time between sweeps . Increases the
holdoff time by at least a factor of 10. This control
improves the ability to trigger on aperiodic signals
( such as complex digital waveforms ) .
TOTALIZE -
Press in both
FREQ and
PER but
tons .
Counts trigger events
in the A
Trigger circuit
( instrument
in A
HORIZONTAL
MODE ) or the
B
Trigger
circuit
(
instrument
in
ALT or B
HORIZON
TAL
MODE ) . The
displayed count
can be reset
to
zero
by
switching
between A
and ALT
HORIZON
TAL MODE or by
pressing
in
momentarily the SGL
SWP RESET button .

Refer to Figure 2-7 for location of items 35 through 38 .
35 UPPER FUNCTIONS - LOWER FUNCTIONS Switch
Push - push switch that determines which set of CTM
functions is activated by the Function Select switches .
WIDTH - Measures the width of the trigger signal
from the output of the A Trigger circuit ( instrument
in A HORIZONTAL MODE ) or the B Trigger circuit
( instrument
in ALT or
B
HORIZONTAL
MODE ) .
With the trigger slope switch in positive position ,
the CTM measures the positive displayed half cy
cles of the trigger signals ; when in negative posi
tion the CTM measures the negative displayed half
cycles of the trigger signals .
36 Function Select Switches Five button switches
along with the UPPER FUNCTIONS - LOWER FUNC
TIONS switch select the CTM functions . With all the
switch buttons out , the CTM is disabled and the read
out is
blank .
DCV ---
Measures de voltage
from to 499.9
volts
when applied to
the
Multimeter
inputs . The
word
" OUCH ” is displayed if 500 V or more is applied to
the
Multimeter inputs .
With the UPPER FUNCTIONS - LOWER FUNCTIONS
switch in the IN position the following CTM functions
can
be
selected
.
12 / - (
Resistance /
Semiconductor )
Measures
resistance up to 1.99 G ( OHMS ] or indicates that
the device - under - test is a forward - biased semicon
ductor when applied to the Multimeter inputs .
FREQ - Measures the frequency of the trigger sig
nal from the output of the A Trigger circuit ( instru
ment in A HORIZONTAL MODE ) or the B Trigger
circuit (
instrument
in ALT
or B
HORIZONTAL
MODE ) .
With the
UPPER
FUNCTIONS
- LOWER
FUNCTIONS
switch
in
the OUT
position the
following
CTM func
tions can
be selected
.
ال
PER — Measures the period of the trigger signal
from the output of the A Trigger circuit ( instrument
in A HORIZONTAL MODE ) or the B Trigger circuit
( instrument in ALT or B HORIZONTAL MODE ) .
A TIME -
Provides two
intensified zones on the crt
trace
for
differential
time
measurements . The
loca
tion of the first intensified zone is determined by
the B DELAY TIME POSITION control , and loca
