Tektronix 2465A Oscilloscope Repair – Part 8

CAL 03 – Triggering

The purpose of this section is to set the triggering levels for the 4 channels of the scope.

I didn’t capture photos of this, as it went by so fast, I forget to get snapshots.  But all that showed was the normal display of Channel #, Input Voltage and Step number.  There were no waveforms displayed.

The scope automatically runs steps 201 – 214 when you start the procedure.

Then in steps d – g, you are inputting a 500mv square wave to channel 1 and stepping through steps 215 and 216.

Steps h – k uses a 500mv square wave to Channel 2 to step through step 217.

Steps l – m uses a 500mv square wave to Channel 3 for step 218.

Steps n – o uses a 2 volt square wave to Channel 3 for step 219.

Steps p – q uses a 500mv square wave to Channel 4 for step 220.

Steps r – s uses a 2 volt square wave to Channel 4 for step 221.

It was all very straight forward…
