Troubleshooting the Analyzer

 

To troubleshoot trigger failures

Connect the frequency synthesizer to the analyzer’s rear panel EXT TRIG connector using a BNC cable.

Press the following keys allowing enough time for the analyzer to trigger before pressing the next key. Note which trigger modes are failing:

[ CHANNEL 1 ] [ CHANNEL 2 ]

[ CHANNEL 3 ] (option AY6 only)

[ CHANNEL 4 ] (option AY6 only)

[ TRIGGER SETUP ] [ CHANNEL LEVEL ] 200

[ mV ]

[ SLOPE NEG ]

[ ALL CHANNELS ] [ CHANNEL DELAY ] 100

[ mS ] [ 0 ]

[ S ]

[ Rtn ]

[ ARM SETUP ]

[ MANUAL ARM ] [ Rtn ]

[ ARM ]

[ ARM SETUP ]

[ AUTOMATIC ARM ] [ Rtn ]

[ EXTERNAL TRIGGER ] [ TRIGGER SETUP ]

[ EXT LEVEL TTL ]

[ EXT LEVEL USER ] [ USER EXT LEVEL ] 200

[ mV ]

[ EXT RANGE +/10 ]

[ USER EXT LEVEL ] 0

[ V ]

The message WAITING FOR mode TRIGGER is displayed when the analyzer is not triggering.

Change the frequency synthesizer’s amplitude to 0.3 Vp-p.

Press [ EXT RANGE +/ 2 ].

The analyzer should now trigger.
