The Model SA-302 System Analyzer is designed as a substitute for the TV camera to isolate trouble in the Cyclops TV System during a malfunction.

FEATURES:

A.            Identifies cable trouble (open-short, etc.)

B.            Long life LED lamps.

C.            Wide range power line voltage.

D.            Advanced integrated circuitry.

E.             Short circuit protection.

F.             "Lamp hold" circuit to catch intermittent problems.

G.            Monitor calibration capability.

USAGE:

System Analyzer should be used in the following case:

When the system is not operating properly, the analyzer may be used to locate the problem to prevent shipping a good camera to the service center unnecessarily.  Use the analyzer before connecting camera to a repaired system to prevent damage to the camera.  Before going to the field for inspection work, use the analyzer at the shop to make sure all components of the system are functioning properly.

LAMP FUNCTION:

System Analyzer SA-302 is equipped with 6 light emitting diode lamps (L.E.D.). 2 yellow lamps to check power circuits, 2 red lamps to check the video circuit and 2 green lamps to check the transporter power circuit.  The two yellow lamps should be lit and the two red lamps should not be lit under normal operating conditions.  A green transporter lamp should light up when the speed control on transporter controller is operated.

OPERATION:

1.      Disconnect the TV camera from the system under question.

2.      Connect the "System Analyzer" to the system, replacing the camera at the end of the cable.

3.      Turn the system "ON".  Set all controls to normal operating values.

4.      Watch the TV monitor screen.

5.      If the grid pattern shows on the screen and only the two yellow lamps light up, the system (other than the                      camera) is normal.  

NOTE: Wiggle all cable connections to be sure there are no intermittent problems.

6.      If the system is normal, turn off the system, remove the analyzer   and reconnect the camera.  If no picture appears on the monitor, the camera is the problem.

7.      If the grid pattern does not show on the monitor screen, check the lamps as instructed in the next section.

8.      If the analyzer shows a problem with the system, DO NOT connect the camera.  It may damage the camera circuitry.

9.      If the system analyzer shows any problem in the system, disconnect the cable reel umbilical cable from the back of the camera controller, then connect the analyzer to the back of the controller using the test cable. 

         If this solves the problem, the location of the trouble is in the main cable area, i.e. main cable, cable reel, slip rings, and/or umbilical cable.  Refer to the trouble shooting section of this manual to locate the specific location of the problem.

TROUBLE SHOOTING:

1.      The lighted yellow lamp marked "Camera Power" indicates correct camera voltage.  If this lamp does not light, check the camera power fuse on the control unit and camera power wires connected to terminals "B" and "E" on the cable connector.

2.      The lighted yellow lamp marked "Light Power" indicated power applied to the light circuit.  If this lamp does not light up, check the light power fuse on the controller and the light power wires connected to terminals "A" and "F" on the cable connector.

3.      The lighted red lamp marked "Video Short" indicates the video line, (center wire of co-axial Pin G of the connector) is shorted to another conductor.

4.      The lighted red lamp marked "Video Open" indicates the video line (either center wire or the shield of the co-axial cable) is open somewhere in the system, or shorted to one of the light power lines. (See section 5)

5.      If the red lamp marked "Video Open" lights up, it may indicate the video line is shorted to one of the light power lines instead of open.  Rotate the light voltage control on the control unit to zero (CCW).  If "Open Lamp" turns off and "Short Lamp" comes on the short is between the video line (Pin G) and one of the light power lines (Pin A or F). If "Open Lamp" still lights up, the video line (Pin G) is open.

          This could indicate one of the following:

(a)     Open in the camera cable.

(b)     Open in the jumper cable.

(c)     Bad connection on the slip ring (commutator).

(d)     Open circuit in the control unit.

(e)     Open wire or loose connection of co-axial cable between the control unit and the monitor.

(f)     The termination switch located at the back of the monitor is not in the correct position.  Refer to system manual for proper video termination.

         Some control units are equipped with a "Signal Meter" and the meter will show "Zero" in the case of a, b, or c and "Full Scale" (always to the right) in the case of e and f.  If the monitor screen shows a very blurry picture and a tail appears on the right side of an object, the trouble is either e (open shield) or f. If the monitor screen shows nothing the problem could be a, b, c, d, or e.

6.      When both red lamps light simultaneously and stay lit, it is an indication that video line "G" is shorted to one of the power lines, "B" or "E".

7.      When testing relatively long cable (500 ft or more) the resistance of the cable may confuse the analyzer.  Also, the analyzer may not catch a short on the other end of a long cable.

8.      If the trouble cannot be located while the analyzer is connected at the end of the main cable, connect the analyzer to the front of the control unit with the test cable and place the input switch to the "Front" position.

         If troubleshooting a portable system, disconnect cable from reel at the rear of the control unit (see photo showing back of control units) and connect the analyzer to rear of control unit using the test cable.  If system tests normally at this connection, the problem is in the main cable assembly.

9.       If the system contains a VCR, DVR or a data generator, disconnect them and connect a video (co-axial) cable directly between the control unit and the monitor.  If the system becomes normal when these are bypassed, the problem (open or shorted video circuit) is probably in one of them.

10.     When the video line is shorted to either the camera or the light power lines, usually both the video output circuit in the camera and the termination resistor (75ohm 1/2 watt) in the monitor, data generator, arrowhead generator, VCR or DVR whichever is connected right next to the control unit, will be burned out.  In this case, the shorted cable (or whatever) and the burned component will have to be repaired.

11.     Both the "Video Short" and the "Video Open" lamps are equipped with a holding circuit.  One tenth of a second of short or open will light the red lamp for approximately two seconds to help in finding intermittent shorts or opens.  Wiggle all cable connections while under test.  Any intermittent short or open should be found and repaired before reconnecting the camera to the system.

12.     If the system is equipped with a self-propelled camera transporter that is not operating, connect the analyzer as in check #13 above and rotate transporter speed control knob as if to power transporter.  Either Forward or Reverse green transporter lamp should light. depending on the orientation of the direction control knob on the front panel and the toggle switch on the back panel of the controller.  If the green transporter lamps light up, the transporter controller, TV cable and connectors for the transporter power circuit are normal and the transporter is probably at fault.  If the lamps do not light up, check the controller fuse and proceed as in check #9 to isolate the problem.

VIDEO MONITOR CALIBRATION:

         While the system is in a normal condition, the video monitor may be calibrated with the SA-302 Analyzer.  Adjust vertical linearity and height in the monitor to make all horizontal space equal.  To adjust vertical height precisely, make six vertical equal in size to five horizontal spaces at the center of the screen.

 SERVICING:

         The only user serviceable part in the SA-302 System Analyzer is a fuse.  Unscrew the four screws on the top of the unit to remove the cover.  Replace the defective fuse with a 3AG size fast blow 1 amp fuse.  If a new fuse does not solve the analyzer problem, send it to the service center for repair.
