Check 500 Khz Trigger Sensitivity; Check 5 Mhz Trigger Sensitivity; Check 50 Mhz Trigger Sensitivity - Tektronix 2212 User Manual

Performance Tests
Step 2. Check 500 kHz Trigger Sensitivity
a. Connect the leveled sine-wave generator output via a
50
n
BNC coaxial cable and a 50
n
termination to the
CH 1 OR X input connector. Set the SEC/DIV to 2 µs.
b. Set the leveled sine-wave generator to produce a
3.5-division display at an output frequency of 500 kHz.
c. Set the CH 1
VOLTS/DIV
switch to 1 V.
d. CHECK - That a stable display can be obtained by
adjusting the Trigger
LEVEL
control for each switch
combination given in Table C-4 with
DC, LF REJ
and
AC
Trigger
COUPLING;
and that the display will not trigger
with
NOISE REJ or HF REJ
Trigger
COUPLING.
Ensure
that the TRIG'D light comes on when triggered.
Step 3. Check 5 MHz Trigger Sensitivity
a. Connect the leveled sine-wave generator output via a
50
n
BNC coaxial cable and a 50
n
termination to the
CH 1 OR X
input connector. Set the
SEC/DIV
to 0.2 µs.
b. Set the leveled sine-wave generator to produce a 3.5-
division display at an output frequency of 5 MHz at
0.1
V/DIV.
c. Set the CH 1
VOLTS/DIV
switch to 1 V.
d. CHECK - That a stable display can be obtained by
adjusting the Trigger
LEVEL
control for each switch
combination given in Table C-4 with
DC, LF REJ
and
AC
Trigger
COUPLING;
and that the display will not trigger
with NOISE REJ or HF REJ Trigger COUPLING. Ensure
that the TRIG'D light comes on when triggered.
