Maintenance— 2213 Service
2.
Set the CH 1 and CH 2 VOLTS/DIV switches to the
same position; then remove their knobs by pulling straight
out from the front panel. Note switch positions for
reinstallation reference.
3.
Use a 9/16-inch nut driver to remove the nuts secur
ing the VOLTS/DIV switches to the front panel.
4.
Disconnect the following connectors from the
Attenuator/Sweep circuit board;
a. PI 011, a four-wire connector located behind the CH 1
VOLTS/DIV switch assembly.
b. P2011, a four-wire connector located behind the CH 2
VOLTS/DIV switch assembly.
c. P7000, a seven-wire connector located on the rear
edge of the circuit board.
d. P6000, a ten-wire connector located on the right edge
of the circuit board.
5.
Remove three screws which secure the shield to the
Main circuit board (located on the bottom of the Main circuit
board).
6.
Loosen but do not remove two screws securing the
front of the shield to a bracket on the front panel. These
screws are accessible from the bottom of the instrument
through two holes along the front of the Main circuit board.
7.
Pull the Attenuator/Sweep circuit board and shield
assembly straight back from the front of the instrument until
the circuit board interconnecting pins are disengaged and
the switch shafts are clear of the holes in the Front-Panel
circuit board. Then lift out the entire assembly through the
top of the instrument.
8.
If accessibility to the bottom of the Attenuator/ Sweep
circuit board is desired, remove three screws located at
three corners of the circuit board and two screws from the
bottom of the shield and separate the shield from the circuit
board.
To reinstall the Attenuator/Sweep circuit board, perform
the following steps:
9.
If the shield has been removed, secure it to the
Attenuator/Sweep circuit board using three screws
(removed in step 8). Insert two screws in the bottom of the
shield at the front edge (removed in step 8), but do not
tighten them.
10.
Insert the three switch shafts through the holes in
the Front-Panel circuit board and the front panel. Carefully
align the 10 interconnecting pins on the Front-Panel circuit
board with their corresponding connectors on the
Attenuator/Sweep circuit board. Push the board forward
into position, ensuring that the two screws in the bottom
shield engage the front-panel bracket.
11.
Tighten two screws securing the shield to the front-
panel bracket (loosened in step 6).
12.
Reinstall three screws securing the shield to the
Main circuit board (removed in step 5). Then tighten the two
screws installed at the front edge of the shield in step 9.
13.
Reconnect the four connectors to the Attenuator/
Sweep circuit board that were disconnected in step 4.
14.
Reinstall two 9/16-inch nuts securing the VOLTS/
DIV switch shafts to the front panel (removed in step 3).
15.
Reinstall the two VOLTS/DIV knobs at the positions
noted in step 2.
16.
Reinstall the SEC/DIV knob onto its shaft at the
setting noted in step 1 and tighten its set screws.
17.
Rotate the three Variable control shafts fully
clockwise to their calibrated detent positions.
18.
Reinstall the Variable knobs onto their shafts (with
the lettering horizontal and right-side up) and tighten their
set screws.
Front-Panel Circuit Board
To remove the Front-Panel circuit board, perform the fol
lowing steps:
1.
Remove the crt (see the “Cathode-Ray Tube” removal
procedure).
2.
Remove the Attenuator/Sweep circuit board (see the
“Attenuator/Sweep Circuit Board” removal procedure).
3.
Remove the knobs from the following control shafts
by pulling them straight out from the front panel: Channel 1
and Channel 2 POSITION, Horizontal POSITION, AUTO
FOCUS, AUTO INTENSITY, TRIGGER VAR HOLDOFF,
and TRIGGER LEVEL.
